For seven years early in his medical career, Dr. Guthrie served on the island of Guam, where he saw a high incidence of type 2 diabetes in the population there. His experience triggered a keen interest in the effective treatment of chronic disease through lifestyle change. In order to deepen his knowledge in that area and be more effective in his practice, he returned to school and earned a master’s degree in public health with a focus on nutrition from Loma Linda University.
Dr. Guthrie has helped to develop several lifestyle-change programs, including the Complete Health Improvement Project (CHIP), the Wellspring Diabetes Program, and AdventHealth’s CREATION Health program. He is active in the American College of Lifestyle Medicine and has served there as secretary-treasurer, president-elect, and president.
One of Dr. Guthrie’s greatest joys is seeing his patients and community members embrace the principles of whole-food, plant-based eating and watching their health transformations.
Dr. Guthrie is married to the love of his life, Dena. Although they have no children of their own, they were privileged to guide a Marshallese islander, Heidi, through her teenage years. They enjoy making music together, and Dr. Guthrie is skilled at interpreting gospel songs and hymns on keyboard instruments.
