She began her pursuit to learn more about medicine and find out the whys to diseases and symptoms. She was introduced to Functional Medicine and fell in love immediately because it just works. Toni has also trained in facial aesthetics and loves to make patients look and feel beautiful. She has centered her focus on anti-aging approaches to health by utilizing functional medicine and aesthetics in guiding patients in feeling and looking their best. Toni grew up in Portland Oregon where living organically is the way of life. It is the idea that has guided her principles today.
