Do you suffer from symptoms related to food sensitivities, but are unable to pinpoint exactly how or which foods? Do you have chronic health conditions related to inflammation, such as IBS, Migraines, Fibromyalgia, Rheumatoid Arthritis, Colitis, or others? Your everyday foods can often provoke these conditions. As a Registered & Licensed Dietitian who is also a Certified LEAP Therapist, I use the MRT lab-assisted elimination diet to help treat your symptoms related to food intolerances. Having worked in OB/Gyne for 20+ years, I also specialize in all aspects of women's health, from pregnancy to menopause and more.

Do you have an unhealthy relationship with food? Do you get stressed thinking about what to eat? Have you tried different ways of eating to help you feel better and nothing seems to work? Like you, I struggled. I have ADHD, Thyroid Disease, and had disordered eating patterns for many years. I help people identify the root cause of their illness and incorporate nutritional changes. I know what it's like to have a negative body image and be exhausted from thinking about what I could and couldn't eat. Food should bring joy and satisfaction, not stress.

I can review functional test results or recommend one.
Holistic approach. Food First. Science Based. Using a holistic approach, I assess your diet, symptoms, history, tests to understand what your best next steps would be. We'll work on diet & lifestyle, supplements to fill in gaps, and discuss testing if that is something you want to explore. Imagine what it would be like to be free of your symptoms. Have more energy, mental clarity, normal bowel movements and feel good in your own body. Everyone is different. I use food as nourishment, cell signaling, and healing to get you back to being healthy. I don't have one set protocol for everyone. I offer personalized nutrition guidance.
