Hello, my name is Annie Mabashov and I am a certified Functional Diagnostic Nutrition® (FDN) Practitioner and Nutritionist who helps people with nutrition and lifestyle changes using personalized health-building programs.
As a cancer survivor, I know first-hand the impact that functional-based nutrition and lifestyle changes can make to help regain health. After completing chemo in back in 2013, I was cancer-free but still suffered from a weakened immune system, chronic fatigue and recurrent infections. Traditional Western Medicine but did not provide long-term solutions to rebuilding health.
Three years after chemo, I still felt awful and turned to functional medicine. The use of functional lab testing in conjunction with nutrition and lifestyle changes transformed my life and helped me regain my energy and health.
Subsequently, I decided to pursue training in Functional Health and become a FDN-P so that I could help others regain their wellness. I am passionate about cooking clean, simple healthy meals, healthy living and coaching clients to achieve their health goals and feel like the best version of themselves.
