Dr. Harrison's Center of Functional Medicine

Fantastic experience: To start, Dr. Harrison was able to address and resolve in six months what other doctors couldn’t figure out in three years. I’m in my late 20s, and over the last few years I began noticing major changes in my energy, sleep, mood, and overall well-being. I tried different diets, workout routines, medications, and was even misdiagnosed as bipolar. After bouncing between multiple doctors and still not getting answers, I was referred to Dr. Harrison and he pinpointed the issue almost immediately. He put me on a targeted supplement plan and helped me implement several lifestyle changes that made a dramatic difference within 60 days. His knowledge and attentiveness is exceptional, and it honestly scares me to think where my health would be 5 years from now if I hadn’t started working with him. Working with Dr. Harrison has been worth every penny.

Fantastic experience: Dr Harrison has been a godsend. After not getting answers from my doctor and getting pushback on additional tests I asked if we could run, two friends referred me to Dr. Harrison. He had helped them both immensely and I am so glad they connected us. He takes the time to really look at everything, run any tests you ask for, and get to the root cause of things. His program is great at tweaking your lifestyle to yield some big results. I honestly don't think I would have the diagnosis he gave me until bloodwork and symptoms had gotten much worse with my previous doctor. I cannot recommend Dr Harrison enough.

Fantastic experience: I was diagnosed with lupus in the fall of 2024 and it turned my world upside down. I felt exhausted, discouraged, and honestly unsure if I would ever feel “normal” again. When I began seeing Dr. Harrison in the spring/summer of 2025, everything changed. From the very first appointment, he listened with compassion and took the time to truly understand my health story. Instead of just treating symptoms, he looked at the root causes and created a plan that was specific to me. He explained everything clearly, gave me tools to support my body, and helped me see that there was a path forward. Over the past few months, the difference has been nothing short of life-changing. My energy is back, my flare-ups are under control, and for the first time since my diagnosis, I feel like myself again. Some days, I don’t even feel like I have lupus at all—which is something I never thought I’d be able to say. Dr. Harrison is not only incredibly knowledgeable, but he also has a genuine heart for his patients. He celebrates every little win with you, encourages you through setbacks, and truly partners with you on your health journey. He has given me back hope, joy, and confidence in my future. If you are struggling with lupus or any chronic condition and want a doctor who will fight for your health as much as you do, I cannot recommend Dr. Harrison enough. He has completely transformed my outlook and my quality of life.

Fantastic experience: I have been working with Dr. Harrison for the last four months to improve my digestion and sleep issues, both of which have been recurring problems for me for quite some time. Working with Dr. Harrison has been a wonderful experience- he is an excellent listener, a great educator when it comes to issues, and is timely and efficient. My sleep, digestion, other challenges have greatly improved. My overall energy has also been a great improvement- I am much more resilient if I do have a night with less sleep and I have figured out foods that support good energy and the ones that don't. Continuing to follow the plans after my care with Dr. Harrison also has me excited about the future. Highly recommended!

Fantastic experience: Dr. Glenn Harrison is an exceptional functional medicine doctor. He has been incredibly loyal to my family, consistently providing attentive and personalized care. His services are not only affordable but also backed by genuine dedication to his patients’ well-being. Dr. Harrison’s approach to healthcare stands out because he takes the time to educate his patients about their bodies, identifying the root causes of health issues and explaining the best pathways to recovery. Rather than simply prescribing medications, he ensures you fully understand what’s going on and how to improve your health sustainably. His extensive and diversified education allows him to be knowledgeable in most areas of healthcare and the human body’s functionality. Importantly, if he encounters something he doesn’t know, he is honest about it and seeks the correct answers rather than guessing—a rare and admirable trait in any doctor. Dr. Harrison’s commitment to his patients is evident in his willingness to help day and night. While he may not always respond immediately during late hours, he follows up as soon as possible. He is so highly regarded that people fly in from all over the country just to work with him. Our own family friends have traveled from the East and West Coasts, as well as the Midwest, to consult with Dr. Harrison and receive his expert guidance. His reputation as a trusted and effective healthcare provider truly transcends geographic boundaries. I would recommend Dr. Glenn Harrison to anyone seeking to improve their health and learn more about their bodies for long-term healthy living.

Fantastic experience: What Dr.Harrison has done for our little girl is nothing short of a miracle. We had been following protocol given to us by our traditional medical pediatrician for two years after her initial Celiac disease diagnosis, but had seen no improvement in her symptoms, and multiple and increasingly worrisome new symptoms throughout. We were advised to put her on medications that she would have take for the remainder of her life, and at the young age of 11, we weren’t willing to sentence her to the multiple negative side effects that she’d have to deal with. We were looking for healing, not the masking of her symptoms. Our search for an alternative approach to addressing the root cause of her symptoms led us serendipitously to the doorstep of Dr. Harrison. After completing a thorough and in depth exam with labs, we discovered that our girl had also developed all the markers for Juvenile Rheumatoid arthritis. So we now knew that we were dealing with not just one, but two autoimmune disorders. From the minute we made contact, Dr. Harrison listened genuinely to our concerns, and together, we formulated a treatment plan that would relieve our daughter of her constant pain and suffering. His approach was refreshingly thorough, insightful, and consistent with what we had hoped for her healing journey. His friendly and caring approach made all the difference when we were trouble shooting various aspects of our daughters illnesses, and in many ways, we feel we have gained an incredible ally and friend. Now that we’re approaching the completion of her course of treatment, I can confidently say that our daughter is no longer a prisoner to her pain and suffering. She is returning to the active lifestyle she once knew and loved, and where once sat a depressed, exhausted and sedate 11 year old little girl, now stands an eager, energetic and outgoing gymnast who is currently rebuilding her stamina and physique in order to participate in her beloved sport of competitive tumbling. Dr. Harrison saved our daughter from a lifetime of nasty pharmaceuticals and side effects, and brought us to a place of true healing and joy we had never thought possible. Our daughter is living proof that Dr. Harrison is an extremely effective and yet, humble, healer whose knowledge and expertise will change lives. Our only hope is that someday, Dr. Harrison’s healing approach and continued research will flood the masses of traditional medicine, and change it from one of masking symptoms, to one of true healing and vitality. Thank you, Dr. Harrison, for saving our little girl. There are no words to adequately express how deep our gratitude goes for your time, your knowledge, devotion, and love for humanity.

Fantastic experience: I found Dr. Harrison when I was at a very low point in my life dealing with unexplained neurological symptoms. I couldn't get timely appointments with allopathic doctors, and Dr. Harrison's compassion and empathy truly got me through those times-- He goes above and beyond, and genuinely cares about helping you. After 4 months of working with him, my symptoms are mostly gone and we've ruled out the scary diseases. I feel better than I ever have in my life: more energy and no mid day crashes, falling and staying asleep and waking up easily in the morning, and getting sick less frequently. I feel confident I now have the tools to keep my symptoms from flaring again and staying healthy from here on out. I can't thank Dr. Harrison enough!

Fantastic experience: I had been suffering with digestive issues for over a decade and adrenal fatigue for maybe half that time. Constant searching for symptoms/solutions online and a vicious cycle of ups and downs really had me in a sad and depressed state. Dr Harrison has truly changed my life. His approach is kind, thoughtful and thorough. I now have the answers I was looking for as well as the tools to navigate life. Thank you so much for helping me

Fantastic experience: I have completed Phase 2 out of 3 of Dr. Harrison’s clinical workup, and my experience has been outstanding. Dr. Harrison is the only doctor who has given me hope for resolving my inflammatory skin condition without relying constantly on medication. From the initial discovery call to the physical examination, his compassion, expertise, and professionalism have been evident throughout. I am eager to return to his practice as soon as I have the finances to continue. I feel reassured that I am in good hands with Dr. Harrison

Fantastic experience: Dr Harrison helped me when our medical system left me behind. Wish I would have found him years ago!

Fantastic experience: After decades of dealing with various health issues that were never properly resolved in the more ‘typical’ medical setting, I decided to take the functional medicine route. And I’m so glad I didn Dr. Harrison has been amazing - responsive, knowledgeable, involved while also giving me the tools to manage my conditions myself moving forward. My quality of life, and what it means for the future, is better than I could have anticipated. Thank Dr. Harrison!

Fantastic experience: Dr. Harrison is a step above the rest, he will actually take a look at your problem, he will find the root cause, and he will help you address it in the healthiest ways possible!

Fantastic experience: Dr. Harrison is amazing. His knowledge, care and attention is outstanding. Dr. Harrison brings calm, clarity and confidence to patient conversations and to the patient experience. I am clear Dr. Harrison is a force of nature, committed to health and well being in the world. Who he is for me is a powerful leader and remarkable contribution to my health issues and concerns. If you are looking for clarity and confidence and an action plan in what you are dealing with, do not waste one more minute and contact Dr. Harrison.

Fantastic experience: I started seeing Dr. Harrison after progressively worsening joint (ankle mostly) pain flare ups. My pain was so bad that it would wake me up at night and there was no pain meds that could touch it. I wasn't able to get up and do anything on the weekends or evenings and I was pretty much bound to the couch. I had to use crutches to get to and from work. It started to affect my mind when I thought about not being able to hike with my wife and play with my kid (I'm 48 now.) It was painful to do anything, and I knew I had to do something. When the flare ups happened, they started to last for a couple of months at at time. I met with Dr. Harrison for an introductory call and he was confident he could help. He explained that it was likely an autoimmune disorder of some sort that was too early in the stages to be formally diagnosed by a rheumatologist. He talked to me about how we could address the root cause of what was going on. When we started meeting weekly, he gave me small changes to implement. The small changes made the process seem doable and as the small changes added up, my life started to change. First and foremost, the pain went away. I started to think that maybe I would be able to be active again. At one point, I had a flare up and I got down, but Dr. Harrison assured me that it wouldn't last long. Sure enough, he was right. This one only lasted about 24 hrs and the intensity of the pain was nothing compared to previous flares. With his guidance I continued to make changes and every small changes continued to help. He educated me about so much that I had never thought of, and at each step, he made sure I was comfortable with the changes. I saw him for a total of 4 months. During the 4 months, I became mobile again, my mental state changes to much more hopeful, I went from 196lbs to 171lbs and I can wear my old clothes again. (The weight loss is just a byproduct of addressing the root cause of the joint pain). Since my weekly meetings with Dr Harrison are over, I now have the tools to continue the changes we implemented, on my own. Most doctors would try to string you along for years and put you on all kinds of medication that cause other side effects. Dr. Harrison fixes the root of the problem and teaches you how to live your life post doctor visits. If you are experiencing pain of any sort, I'm confident Dr. Harrison can help you. I'm also confident that if he doesn't think he can, he will be honest with you (but he can). During the whole process I felt like he was genuinely invested in wanting to see me feel better. He is extremely detail oriented and will work to understand what is really going on with your body. This does require some work on your end, but his approach makes it easy to follow his recommendations. Give him a call. It will literally change your life.

Fantastic experience: Yes! Highly recommend. It’s hard to swallow the cost at 1st, but WORTH IT. We would’ve paid more $ in the long run trying to manage chronic pain and irreversible joint damage that would’ve developed had we not seen him. I truly believe he prevented a lot of joint damage that would’ve resulted in chronic pain by working to figure out what is triggering the severe inflammation & help his body heal. He is preventative (and helps reverse damage), not reactive medicine. I learned so much getting to sit in on my husband’s appts. My husband has been paid to meet with him 3 to 4 months. I cannot say enough good things and have absolutely zero red flags. Dr. Harrison has a great understanding of true health rather US “health.” He’s down to earth, realistic and easy to talk to you. My husband started seeing Dr. Harrison Oct 2023 after having unexplained inflammation so bad he could barely walk for 3 weeks or so. He was pretty couch bound, and becoming more depressed. His foot, ankle & even up to his calf were swelling pretty badly and we couldn’t get it to improve. It started as gout, but seems to be showing more signs of rheumatoid arthritis. Rheumatologist are much more bound by insurance companies. Dr. Harrison is much more natural methods And lab ranges based on truly healthy people rather than general population in the US to balance out his body. His plan was to see my husband for 3 - 4 months, then we do not continue paying and can see him only if/when needed. We are so thankful.

Fantastic experience: My experience with Dr. Harrison has been truly amazing and transforming. I came to him literally at my wits end. I was truly ready to give up on my body thinking I would never feel normal again. I was diagnosed with uterine fibroids several years ago after I had noticed changes in my menstrual cycle. Heavy flow, severe cramping, headaches, brain fog, intense mood swings. Plus having other issues such as, severe heartburn, loss of energy and just the inability to sustain the healthy lifestyle I had once been committed to. I was so tired of being told that the only options were surgical or to be on synthetic hormones (i.e. Birth control) for the rest of my life. After speaking to Dr. Harrison the first time he agreed to take on my case. We discussed the possibility of natural treatments not being that effective depending on the severity of my fibroids. Dr. Harrison was so incredibly in depth with his approach. Looking at all of my symptoms, little or big. After discussing my intake paperwork in depth, he ordered bloodwork to coincide with my specific symptoms. After getting those results, we got to work. I cannot begin to tell you how happy I am today. I can tell you that my symptoms are so radically different than when I started in June. My heartburn is gone (after years of taking OTC medication for it), my energy is back, the incredibly heavy periods are back to being manageable again. I feel like I have a new lease on the rest of my life. You just have to be %100 ready to commit to yourself and trusting the process. I could not be more happy and thankful to Dr. Harrison.

Fantastic experience: I have absolutely loved working with Dr. Harrison and have nothing but wonderful things to say about the experience. I came to him with digestive issues I have dealt with for my entire adult life, postpartum mood swings and depression for the last two years and one year of long Covid that caused severe insomnia and anxiety. I have seen improvement in every single one of these areas. I have worked with several doctors, gone to therapy, and tried different medications over the last two years to treat the listed symptoms and saw no improvement at all. I expected a functional doctor to be able to help me with the digestive issues, but never expected I would see such a massive change in my mental health. I highly recommend Dr. Harrison and would encourage anyone with persistent physical or mental health struggles to work with him.

Fantastic experience: I have been working with Dr. Harrison for only 2 months and already I am seeing major gains. My labs have improved exponentially and I am noticing an increase in energy levels, and decreased recovery time from flares. My liver numbers are in normal range and I didn't have to take medicines to get it there. I have worked with other functional medicine doctors before, but none took the time to explain what we were doing and why. His approach makes sense and I do not have negative side-affects from the treatment as I did in the past. He has helped me more in 60 days than my doctors have helped me in two years. This is the best investment that I've made in myself and I am all in, because I know Dr. Harrison wants to see me win as much as I do it makes it that much easier to stay on track. (Picture below is me healthy and enjoying life...for the first time in a long time I believe I am on my way back to an active me and I can visualize myself there again.)

Fantastic experience: When I first came to Dr. Harrison I felt like I only had a few good years left. I could keep my labs stable, but couldn't get them to come down, and I was at the max dose of medication. I was diagnosed with autoimmune hepatitis in March of 2020 and began working with conventional doctors. It wasn’t until I found Dr. Harrison on my journey that I started feeling that I have a chance to live a long active life. While I knew that a change in diet and lifestyle was the right direction, I did not completely understand how to go about doing that. He was able to teach me so much, and in my three months with him my lab numbers were dropping and they continue to get better. I was taught how to work this on my own but know he is there when/if I have questions. I recommend Dr Harrison to start your journey. Wendy

Fantastic experience: My experience with Dr. Harrison has been the best I've ever had with a healthcare provider! He truly digs in deep, gets creative with solutions and possible causes, and I genuinely believes that he cares about what I'm going through and finding a solution. It's really refreshing to not have someone give up on you or push treatment plans you don't agree with. My health journey has already made a complete 180 and I'm eager to continue working with him!

Fantastic experience: Dr. Harrison has changed my life. I have struggled with uncontrolled Hashimoto’s for the past seven years and was diagnosed with Celiac Disease in January. I could not figure out how to manage my symptoms, and my primary care doctor told me there was nothing else they could do for me. The physical pain and emotional distress that I was experiencing was devastating. I was feeling hopeless, and scared I was missing out on life with my young daughter. One of my friends told me about functional medicine, and after a quick google search I found Dr. Harrison’s practice. I immediately scheduled a phone call to discuss my case with him, and this decision has saved my life. He was immediately compassionate and assured that if I did the work, I could indeed get better and still live a full life. Dr. Harrison and I are still in the early stages of working together, yet I have already experienced spans of time where my body and mind feel better than they have in years. The steps he gives me after each appointment are clear and he helps to make sure I understand the why of everything we’re doing. I never feel overwhelmed by the new changes we are making. I am positive that I have a full life ahead to share with my precious daughter. Dr. Harrison’s expertise combined with his empathy are unique and extremely essential for anyone who is dealing with chronic health issues. I highly recommend Dr. Harrison to anyone who needs help, or who may feel like they’ve lost hope for healing. Dr. Harrison has provided me with such a powerful message that there is always hope to feel better and change your life.

Fantastic experience: Dr. Harrison definitely got me on the right track to manage my digestive issues and Hashimoto's. My overall health has greatly improved by working with him. So grateful.

Fantastic experience: I had been struggling with hypertension for a long time and tried many different natural protocols to no avail. At 75 I finally agreed to go on blood pressure medication. My medical doctor had me try two medications in various combinations and strengths to no avail and with many side affects, then a third one. During this period it was recommended that I try a “functional” doctor. I was surprised as I didn’t know what that was. After researching and finding Dr. Harrison, I called and made my first consultation . After the initial consultation, exam and labs were done, Dr. Harrison explained in great detail the results and I felt hope again. He started me on some Supplements, diet changes, along with some activities. Every time I talk with Dr. Harrison I feel he grasps my health issues and understands my goals and he works in conjunction with my medical doctor. I feel incredibly blessed to have found Dr. Harrison and look forward to a long term healthy lifestyle with his counsel. Dr. Harrison is very knowledgeable, and I would highly recommend him.

Fantastic experience: I was diagnosed with Lupus at the age of 18. Over the years I've found alternative and functional approaches that really help me to maintain a full and healthy lifestyle. However, about 2 years ago I was struggling a bit and missing just a couple final pieces in my treatment and maintenance schedule. After only a few sessions of working with Dr. Harrison we were able to nail down these last few considerations that I had previously missed. I can say that without Dr. Harrison I would have likely had to start taking other prescription meds to keep my inflammation levels in check. But with his help, I'm rather symptom free without the nasty side effects of another med. Thank you Dr. Harrison!

Fantastic experience: Dr. Harrison has changed my life! I was struggling to heal after a toe fusion and realized I had low vitamin D levels. I went to Dr. Harrison hoping to raise those levels and allow my toe to fuse. After a couple months with Dr. Harrison not only did my D levels come up and my toe fused but I also lowered my cholesterol by 50 points, got rid of a daily headache I’d had since my teens, and kicked my dependency on heartburn drugs while no longer experiencing heartburn symptoms. Most importantly I truly feel great for the first time in years! Dr. Harrison guided me through this journey while providing detail information on what was happening in my body, what we could do to change it, and why each step was important to the overall goal. Dr. Harrison also has a calm, approachable manner which makes the process much easier. Again, Dr. Harrison transformed my entire wellbeing!

Fantastic experience: After years of stomach issues, brain fog, low immune system, ibs flare ups and feeling hopeless after several endoscopy’s and colonoscopy’s and no answers other than I was “fine” I found Dr. Harrison. Immediately I felt kindness and felt I was being heard and action was taken right away. I finally feel normal and healthy again. It’s a journey and it is not an overnight fix, however it’s worth the time. My immune system is better, no flare ups, no bathroom issues and there’s been lots of victories along the way. I also learned about my hormones on this journey and connected many dots on my condition . It feels good being healed and heard ! I cannot thank him enough!

Fantastic experience: I have suffered from long-term, complex medical diagnoses and Dr. Harrison provided some of the most comprehensive information that has vastly improved my health and emotional well-being. His considerable understanding of the human body and his thorough evaluations through testing, supplements, and routines has changed my life. I am more confident about how to manage my symptoms, as well as adhere to the solutions recommended by Dr. Harrison. His professionalism and compassionate demeanor has allowed me trust and believe that I can have a healthy, and productive future. He is absolutely one of a kind.

Fantastic experience: Dr. Harrison is simply amazing. The last four months have been absolutely life changing. My sleep patterns, my diet, my energy levels throughout the day and my overall health have all drastically improved since I started this journey. For as long as I can remember I've had trouble sleeping which led to feeling exhausted throughout the day. Everything I seemed to eat upset my stomach. I had headaches daily. The thought of doing anything after work besides going home and crashing repulsed me. My enjoyment of life was quickly diminishing. I had gone to my PCP many times about these issues but was always met with minimal effort in finding a solution. The best part about working with Dr. Harrison was feeling like we were a team working together. That was very important to me being someone who is serious about my health. He helped me implement changes in my diet that weren't nearly as hard as I thought they'd be. Any time we tried a new supplement or changed our plan of action he explained why in detail, making it so much easier to stick to. I especially loved going over the lab work with him because his extensive knowledge of how the body works was fascinating. I've worked in healthcare for over ten years and he taught me so much these past four months. Seeing all my lab work level out was a bonus and really made me feel good knowing all my efforts were worth while. The weight loss was great too! I'm so thankful I stumbled upon the Center of Functional Medicine. I had no idea how much one little google search could change my life. I will be recommending Dr. Harrison to everybody!

Fantastic experience: I came to Dr. Harrison after being told I needed my gall bladder removed. I had been experiencing 6 months worth of occasional painful gall bladder attacks. I was referred to a surgeon who wanted me to have my gall bladder removed, but my daughter from Colorado stopped me and said I MUST contact this Functional Medical Doctor in the Denver area (I am from Michigan). I had a call with him and he shared that he felt he would be able to help me out. I figured, what have I got to lose. Fast forward to the present, and I have had ZERO attacks in 5 months. After some bloodwork, we found there were other digestive issues in my body that we are now working on. These digestive issues have probably been going on for many years after looking back at my life, and the gall bladder was the "weak point" in my body that it chose to attack. I have had a lifetime of high cholesterol which is continually been going down every month because of Dr. Harrison's program. I have also had chronic headaches since a life threatening car accident 5 years ago. I have gone from 3-4/weekly to 2-4/monthly. Our goal is ZERO. :-) Everything Dr. Harrison does is natural and makes so much sense. Mainstream medicine always wants to prescribe a pill or surgery, but Dr. Harrison works with you naturally and really cares about you succeeding and getting better.

Fantastic experience: I have been working with Dr. Harrison for a little over a month and have already experienced very positive changes! My brain fog is lessening, my energy has increased significantly and my stomach issues are so much better. Dr Harrison is incredibly knowledgeable and explains things so I can understand the why and how. Having him walk along side me during this healing process is very encouraging and I’m so thankful to finally find someone who can help me after 30 plus years of health problems.

Fantastic experience: Seeing Dr. Harrison has truly been a gift. My daughter and I both received care for autoimmune disorders, stress, stomach, liver, and hormonal issues, and the results have been amazing! He left no stone unturned, ordering appropriate diagnostic tests to gain a complete understanding of our issues and to make valuable recommendations which got to the root cause of our problems. After 120 days of adhering to his protocol, we have both lost weight (my daughter over 20 pounds), are sleeping better, have seen skin issues clear, have better digestion and less inflammation (which has translated to less pain). Our autoimmune and hormonal issues have stabilized and my stress hormone level, cholesterol, and liver enzymes are now in the optimal ranges. We have learned skills that we will continue to use to maintain our progress, and have a better understanding of how we can take charge of our own health. After years of struggling with mainstream medical professionals that never seemed to offer solutions, I can absolutely recommend Dr. Harrison. His fees are all inclusive; a tremendous value given the services and products provided, and there is no price that can be placed on the results we have achieved.

Fantastic experience: Dr Harrison has been great to work with. He is incredibly empathetic and knowledgeable. I really appreciate the depth of lab tests he’s had me take, and how thorough he has been in explaining the results. Because of this, we were able to uncover some key issues that are making my symptomatic. It’s exactly what I was hoping for…a dr who has the patience, knowledge, and experience to help me uncover what has been missed by many other drs.

Fantastic experience: When I first started working with Dr. Harrison, I was losing the small amount of ground I had worked hard to gain in the year and a half since I had been diagnosed with five autoimmune diseases. These were diseases that had surfaced when I was twelve and were dismissed by doctors and more until I was 49. Due to the health issues, digestion has always been a huge challenge for me regardless of the food. When I reached out to Dr. Harrison I was in so much pain after anything I ate, no matter how small the amount, that it caused me to feel like I was in labor. I found myself pacing, bent over at the waist and whimpering my days away. It was a black time. That was last Spring and after a huge in-depth panel of bloodwork which revealed unknown anemias, I was dropping weight fast. By the time I started taking the best supplements on the planet, my 5’5” frame weighed less than a hundred pounds and I had passed out three times in a row while trying to go to the bathroom. It was a very rough time. But the supplements Dr. Harrison had carefully prescribed began working right away. Within three days, the constipation was starting to ease. Fast forward a year, an enormous amount of consistent work on my end and very consistent care on his, I’m in a whole new place. Exercising and getting healthier is my full-time job and I work it hard. Having spent so many decades watching life pass by the other side of the window, I’m becoming less a spectator in my own and more and more an active participant. It is beyond exciting. Just recently, I thanked Dr. Harrison for giving me back a quality of life I had lost when I was 12, and he really really has. Having experienced a similar journey, he gets it and working with him is like working with a medical detective. If you’re struggling with autoimmune issues, I cannot recommend this doctor enough!

Fantastic experience: Dr Harrison and his staff are the best, I contacted him after finding out I'm allergic to 99% of RA medicines and was desperate for help. He looked into my bloodwork, lifestyle, sleep patterns and thru diet and supplements he was able to help me with My RA and Fibromyalgia pain. He made a huge difference in my quality of life, and I can't thank him enough.

Fantastic experience: After working with Dr Harrison over the last several months, I am pleased to report great progress towards understanding and managing my hypothyroid/Hashimoto's auto immune condition. Initial discussions with my PCP lead to a lot of questions and testing but not many answers especially when medication and surgery were ruled out. Dr Harrison has taken the time to help me learn and put into practice a new mindset and awareness around diet, sleep, gut health and nutrition all of which will hopefully keep me on the path of true wellness rather than reliant on medications or as a candidate for future surgical procedures. I HIGHLY recommend Dr Harrison, he is a thoughtful, compassionate and caring partner in health!

Fantastic experience: When I went to visit Dr. Harrison I was suffering from Adrenal fatigue. I had brain fog, memory problems, weight gain, extreme fatigue, sleep disturbances, and painful cycles to name a few symptoms. During my program I underwent a diet change, education, and exercise. I began my journey in July and by August I was on my way to living my best life. I am still on the path to wellness, but I completed my program and I am on my own. I lost 19 pounds, drilled down a better sleep cycle, my energy came back, and my cycles are no longer painful. Dr. Harrison and his staff took the TIME and gave me the tools to get back on track when Western medicine told me, "nothing is wrong." If you question trying the Center for Functional Medicine for fear you will not heal-don't! The only thing you have to ask yourself is are you ready to change your life for the better, and ready to make the commitment?

Fantastic experience: Dr. Harrison is a very knowledgeable thorough practitioner. He has helped me a lot with my thyroid issues and with my digestive issues. He’s very encouraging and supportive.

Fantastic experience: Dr. Harrison is so good at his job. He's incredibly thorough and wants to find the root cause of things, not just treat symptoms. Highly recommended!

Fantastic experience: Dr Harrison really takes the time to listen and understand what you are feeling and where you want to be. I highly recommend Dr Harrison if you want to live a healthier life.

Fantastic experience: I truly do not know where I would be today without Dr. Harrison. He is compassionate, shares his knowledge and teaches well. He got me out of Pain, fatigue, low energy, foggy brain and found the cause of my migraines and arthritis. My first visit with him consisted of me recovering from surgery in which I had 2 disc's replaced and I just could not get recovered from the exhausted dragging, low energy and muscle aches. The arthritis that was supposed to be fixed from the surgery and now in the lower back was painful all the time. In working together Dr. Harrison and I got to the root of the problems. We discovered I had high iron levels which contributed to the arthritis, pain, and low energy. My MD never noticed. I did not know high iron was poisonous to the body. Also I had high cholesterol, high blood sugar, inflammation in the body, migraines I could not fix, and STRESS. Within 5 weeks I began feeling better. I have stayed on my management program and have continued to heal my body. It WORKED! I have NO arthritis pain, fatigue, energy lows, migraines. I am currently working with Dr. Harrison on my stress management which I am learning and fixing. After one year on his program I have never felt better. It was all Worth It!! I spend my time now high performance driving and have no issues with the arthritis, fatigue, migraines, blood sugar and cholesterol. I feel GREAT!!! Thank you Dr. Harrison!!! Fran Hannifin

Fantastic experience: When I began treatment with Dr. Harrison my physical, mental and emotional energy was at an all time low and I admit that I was a bit skeptical that anything could help. After the 4 month treatment program, which I followed religiously, I felt like a new man. These are the specific improvements that I noticed: much more energy, stamina and increased strength, no need for my daily nap anymore, improvement in skin color and texture, improvement in sleep quality with more vivid dreams and snoring decreasing to zero from 20 min./night, more even and calm moods, better breathing, increased mental clarity, lost 25 lbs., blood pressure and cholesterol now back in the normal range. I am happier, more optimistic and can say without hesitation that I feel great! I would highly recommend Dr. Harrison as I already have to many of friends and family.

Fantastic experience: I am very thankful for my treatment with Dr. Harrison. His kindness, dedication and expertise helped improve my health challenge. I appreciated the knowledge and information he presented in the notebook to use during my treatment program and for future reference. Dr. Harrison truly cares for his patients and does his very best to ensure that his treatment is successful! I highly recommend Dr. Harrison! Susan M.

Fantastic experience: Before going to Dr. Harrison, I was fatigued/exhausted, frustrated with gradual weight loss after having a baby (2.5 years ago) and massive brain fog. I was struggling to focus on my work, my family and bettering myself and trying to just make it through the day. I would wake up feeling like I had not slept at all and not truly feeling myself. After 3 months of working with the Center of Functional Medicine, I have my energy back, I have lost 15 lbs (the baby weight and then some) and find my focus and attention have greatly improved. I continue down the path we created with healthy food, supplements and exercise that fit my life. I am grateful for being able to work with Dr. Harrison and creating these results in my life. I would highly recommend the Center of Functional Medicine!

Fantastic experience: I highly recommend The Center for Functional Medicine! Dr. Harrison helped me regain my health and helped me get my quality of life back. He listened to my story in a way that no other doctor did and was able to figure out my medical problems when no one else could. Because of the Center for Functional Medicine, I am grateful that I can enjoy life again!

Fantastic experience: Dr. Glenn Harrison is a trusted friend who I have known for decades. I highly recommend him.

Fantastic experience: I've known Dr. Glenn both personally and professionally for 8 years. I can honestly say he is the most compassionate and knowledgable individual I have had the privledge to work with. Dr. Glenn is incredibly driven and even after earing his Doctorate continued to pursue his education in Functional Medicine, his understanding of human physiology is astounding and I regularly turn to for a consultation when I'm having issues with complex cases of my own. I would highly recommend him to those who feel left behind by the traditional medical model or who are looking for different treatment alternatives. He has the knowledge and compassion to help you make significant changes in your life.

Negative experience: I came to Dr. Harrison highly recommended through a client of my personal trainer. I had high hopes from what I heard about his program. For me, I had been working diligently on my health for 6 months prior to coming to Dr. Harrison. My primary issue is that I thought I was not losing weight fast enough given the effort I was putting in both in a healthy, all natural diet and 5-6 days working out at the gym. I was only losing 3 pounds per week during that 6 month period. I also had been having a major lower abdominal pain issue for about the year prior to my visit that I could not figure out and blamed for the slow weight loss. I had even tried Keto for a couple of months, and although it helped me with many things in terms of energy, joint pain and acid reflux, I could not lose weight,. The first 6 weeks on Dr, Harrison's program I upped my weight loss to about 4 pounds per month, so I thought I was well on my way. I was doing everything he told me to do from triggering my gag reflex when I brushed my teeth to religiously taking the supplements he recommended. Then I left the country for the holidays for a couple of weeks, and while I followed the program for the most part, I did have to partake in some undesirable foods, particularly corn, for cultural reasons - but it wasn't outlandish by any means. Upon my return, I continued the program while working on improving sleep, lowering stress and other issues. We did discover that the SIBO was the likely culprit for the lower abdominal pain, an imbalance of bad bacteria to good. Dr. Harrison gave me a new probiotic formulated for that purpose and my pain finally started subsiding. While finishing up the program, I was told to continue for 6 weeks to be sure and knock it out - so I bought a supply and continued to follow this advice while remaining steadfast on the same diet. However, during this time I could not lose weight and even started gaining weight. I also developed a new rash behind my knees and the existing scalp rash worsened to the point of scabbing. My lower abdomen pain was gone, but my goal of increasing my weight loss was obliterated. Then after the 6 week period when my supplements ran out, my abdominal pain return with a fury. It seems that the supplements acted only as a bandaid to my problem and did not address the underlying issue. The irony is that Dr, Harrison rails against the medical establishment for prescribing drugs simply to cover up the symptoms rather than address the underlying problem, yet that is the exact experience I had on his program. To be sure, Dr. Harrison does have you sign a contract stating that the program may not work for you, and he discusses this with you at the moment of execution. But, what he doesn't tell you is that it just might make things worse, give you additional symptoms and cause you to stop losing weight. For me, 6 months later, I weight 5 pounds more than when I started the program, have new skin rashes, and the rashes I had before are worse. It seems the $5,000 I paid was for nothing as I am worse off than when I started and the things I came to address were made worse rather than better. To make things worse, Dr. Harrison comes across at the end of the program (I just did a 3 month stint) as very caring, and even sends an email to say if you need anything just email. But, when I emailed with the bad news of the worsening rash and the return of the abdominal pains, his response was, "if you want more help you will need to pay for more visits." But, screw me once shame on you, screw me twice shame on me - right? Why should I pay for more advice that made me worse off? Why doesn't Dr, Harrison stand by his work and make things right? Certainly as a business owner making websites, if I had a client that had a broken site I would jump in and make it right without hesitation. But here I think it is really all about the money - not a concern for the patient as evidenced by the actions I experienced. My experience here was not successful, just a snake oil presentation without results.

Fantastic experience: Dr Harrison is amazing, thank you. Highly recommended.

Fantastic experience: Dr Harrison is the best functional medicine doctor I've ever had. He is very caring, a great teacher, and has guided me with my health in the last several years. I am doing well because of his guidance and knowledge. I highly recommend him if you are looking to learn and care for your self. He is the best.

Fantastic experience: Dr. Harrison is great!

Fantastic experience: Dr. Harrison changed my life and the way I look at my health. He is an amazing doctor and I would highly recommend him to anyone looking to make a positive change in their life.

Fantastic experience: We initially attended a seminar Dr Harrison presented and were very impressed by his knowledge and caring demeanor. We have been seeing him for about the past two months and are very pleased with the results we have achieved thus far. He is a doctor who really listens and cares about his patients. His holistic approach makes so much sense. We highly recommended him.

Fantastic experience: Formerly having practiced myself as a chiropractor, I appreciated Dr. Harrison's thoroughness about understanding and implementing functional medicine into clinical, healthcare approach. Without doubt, many future patients will benefit highly from his expertise. To better health...

Fantastic experience: My husband, my daughter, and I have all seen Dr. Harrison and have been impressed by his knowledge, insight, and persistence in assisting us with our health. We each had our unique health issues and Dr. Harrison created a unique plan for each of us addressing our specific health needs, and we all had significant results. Dr. Harrison was open and accepting, deeply knowledgable, supportive, and positive throughout our care. I was at a point that I needed to lay down at work, in-between appointments, and now my husband says I'm back to being me! Thank you so much Dr. Harrison for all you have done for my family!

Fantastic experience: Both my wife and I have completed Dr. Harrison's program. It's safe to say our lives have improved by an order of magnitude since our association with Dr. Harrison. In both of our cases, his exacting lab work uncovered issues that our general practice physicians completely bypassed. In my case, I was able to get off of several psychiatric meds after nearly 18 years under the care of a psychiatrist, (who would've been more than happy to keep me on those meds for the rest of my life.) In my wife's case, it was a food allergy that caused her to suffer three strokes and all the attending surgeries, angiograms, and other tests that went with it. Because of Dr. Harrison's care and attention, we won't spend several thousand dollars on unnecessary medical procedures, or undergo all of that needless pain and suffering. I can't imagine what our lives would be like if we had not have met Dr. Harrison. He has been a blessing to my entire family. The way I see it Western medicine let us down and kept us down horribly. Dr. Harrison lifted us up and showed us how to keep ourselves up, to where the only thing holding us back now is our minds and not our bodies, and now that our bodies are not suffering, we have the time to work on our minds. TO LIFE!!

Fantastic experience: When I began working with Dr. Harrison (at the age od 43), I was anemic, felt sick to my stomach, and had a serious headache that hadn't gone away for a couple of weeks. I had very little energy and was taking naps every 3 to 4 hours. I would still sleep all night and still wake up very tired. After some questioning and diagnostic testing including thorough blood testing, Dr. Harrison was able to determine that I had leaky gut issues and an auto-immune disease. A plan was created for me to get my health back. Through education and coaching, I was able to change my eating habits, taking key vitamins (no drugs), and begin resistance training. Instead of eating fast food and drinking soda, I was eating healthier and drinking water. I lost significant excess weight in the first couple of months and was feeling better each week. A couple of months later, I was increasing the weights I could lift, able to get involved in sports again, didn't need my afternoon naps anymore, I was feeling better than I did 10 years earlier. I am SO thankful that Dr. Glenn was able guide me back into the game of life! I can now run 5k races and play other sports with my kids and have opened up a world of opportunities.

Fantastic experience: Dr. Harrison takes great care with each of his patients. He truly listens and takes the time to commit to helping you at every step of your health journey. He is honest and compassionate and approaches your specific situation in a respectful and caring way. I would highly recommend Dr. Harrison if you are looking to get help when all else has failed.

Fantastic experience: Dr. Harrison is a compassionate and thorough practitioner. He is always thinking outside the box to find the often 'hidden reasons' for most of the major health issues impacting the masses. He is well versed and has the resources to improve your health regardless of the severity or your age. He won't disappoint especially for those frustrated with western medicine and looking for a more holistic approach.

Fantastic experience: My husband and I both saw/seeing Dr Harrison more from the preventative side, wanting to make sure that as we age we are doing it without have to pop a ton of prescription pills that would ultimately lead to other issues. He by far is the best Dr we have worked with when it comes to the education of what's going on, why it's going on and how to correct what's going on. We have felt that we are 100% in control through the entire process. He has a true passion for what he does and wanting his clients know as much about the process and what's happening as he does. I would highly recommend Dr Harrison for any health related challenges of to regain control of your health.

Fantastic experience: Dr. Harrison is an amazing Dr! He takes the time to really dive deep to figure out the cause of your medical issues so that you can resolve the core issue instead of just masking the symptoms.

Fantastic experience: Dr. Glenn Harrison uses advanced diagnostic testing to find and address symptoms patients have. When I worked with Dr. Harrison the blood work I did was far more comprehensive and informative than all previous primary care physicians I have worked with over my adult life. Dr. Harrison does not take insurance but is able to set up payment plans for clients to make sure they are able to work with him. The Center of Functional Medicine wants the best for all clients and does not have the typical model where you may be seen for 15-20 minutes maximum. Dr. Harrison truly cares about each and every client and the results are awesome.

Fantastic experience: It is extremely refreshing to find a doctor like Dr. Harrison who focuses on preventing and fixing health issues instead of masking them with pills. If you are interested in becoming a healthier person in a sustainable lifelong way, I highly recommend you schedule an appointment to talk with him. He takes a consultative approach to find the right plan for each individual person and is a wealth of information, highly recommended!
