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.

My ideal client is an individual or parent seeking to learn more about their food allergy diagnosis, diagnosis related to abnormal gut function. If they have an eating disorder, they are ready to learn how to move past it and repair their relationship with themselves and their food. My clients understand that slow changes are lasting changes are not interested in a quick fix. They are comfortable with my approach that all foods can fit into the eating pattern and health looks a lot of different ways.
