Fantastic experience: I have been working with Tammy for many years now. Years ago after I realized I had an eating disorder, I did research and found Tammy. Tammy helped me go through the emotional process of accepting and understanding my eating disorder(s). After the first appointment with Tammy I was able to Navigate more easily through life which is always surrounded by food. I mean it made sense why I was so obsessed and overwhelmed by food. Because food was always surrounding me in every aspect of life and especially through media, and social media was the worst. Honestly I credit Tammy for guiding me through the chaos of my eating disorders and showing me how I can live life in a healthier way without being or feeling like food was constantly involved or invading my life. What I needed was someone who would be able to be sensitive to my eating disorder, and both hold me accountable for times when I couldn’t eat perfectly or chose healthy foods or didn’t want to eat, or wanted to binge eat. Tammy made herself available to me when I had eating disorder emergencies. But no matter what Tammy was always there. Tammy is always supportive and she makes me feel comfortable with her. Which is huge because I am able to open up and share with her my true feelings about my eating or disorder. And yes it’s very emotional for me to open up but it always feels better after talking about my disorder with Tammy because shes a caring, sensitive, empathetic, supportive and understanding to such a sensitive subject. Tammy has been able to help me to understand my emotional side of my eating disorder which is still in progress because after all im in recovery. Because of my work with Tammy I have been able to stop binge eating, stop hoarding food, stop obsessing about food, accepting my emotions about food, drinking and decrease eating sugar items, stop weight gain, setc. A huge thank you to Tammy!! Because of your support and continued commitment and confidence in my progress I have made so many great strides towards living a healthy lifestyle and a happier lifestyle. I’ve been able to learn to live with my disorder and not allow it control my life. I truly appreciate everything Tammy has done for me. I wholeheartedly recommend Tammy to anyone who needs support or help with their eating disorder, eating habits, change of meal plans, nutrition etc. Because Tammy is a true professional she has all the research, recommendations, knowledge and experience and expertise in this field.

Each session, I learn new skills and am given resources to help change my negative thoughts and destructive behaviors. Unlike some providers, Tammy is an amazing dietitian who will not give up on you and will not make you feel ashamed. If you are looking for a dietician, I highly recommend Tammy!

Fantastic experience: Tammy has been such a blessing in my life. She has helped me to understand my relationship with food and the disordered eating that I have experienced my entire life. She is so compassionate. She does not shove a meal plan at you, say try this and walk away. She has helped me with realistic goals that at times aren’t related to putting food in my mouth but doing the work that will make that easier. She has quickly responded to me any time that I have had questions or needed additional support. Most recently, a relative of mine has been struggling with severe symptoms of gastritis along with other health concerns and was going down hill quickly. She just wasn’t able to eat without getting extremely nauseous. I reached out to Tammy because I truly thought we could lose this person and I knew that the advice they were receiving was not from a professional. Tammy jumped in immediately. She recommended a nutrition shake with the nutrients and calories that she would need to gain some strength as she adds in more foods. I could never thank her enough for this help!

Fantastic experience: Tammy has helped us turn around my 17 year old child’s extremely limited diet. He is on the spectrum and dx ARFID. We have tried everything through the years to help him expand his variety of foods so that meal times can be easier for him and home and in public. Nothing seemed to work until we met with Tammy on an ongoing basis. She quickly gained his trust and built a wonderful rapport with him. He went from eating only about 5-10 processed foods and being very stressed over us asking him to try things —to eating almost every type of fruit and vegetable and able to cope with his feelings with ease. He is working daily to incorporate more foods, his health is improving in every way, he joined a gym recently! He looks forward to meeting with her. Thanks is not enough!!

Fantastic experience: Tammy is hands down the best dietician in STL. I could never have achieved such a healthy relationship with food, eating, and my weight without her.
