As medical director, he oversees the Integrative Medical Advisory team (IMAT) and the development of educational content for practitioners across North America.

Although originally planning to attend conventional medical school, Dr. Keller shifted direction and completed a degree in naturopathic medicine at the Canadian College of Naturopathic Medicine. The shift followed a three-month internship at a rural Kenyan hospital where he worked with doctors who used local food to successfully treat patients, after which he felt compelled to practice a diet-oriented system of medicine. Today, he splits his time working for Fullscript, seeing patients, and developing an innovative regenerative farming operation.
