About
Dr. Katherine Wiegman is a board-certified Family Medicine physician and the founder of GA/MD in Suwanee, Georgia. She holds board certification in Family Medicine and board eligibility in Internal Medicine. A Georgia native, she grew up in Carrollton before earning her Biology degree magna cum laude from the University of West Georgia. She went on to graduate from Mercer University School of Medicine in 2008 and completed a four-year residency in Indianapolis, Indiana.
After training, Dr. Wiegman returned to Georgia and spent four years serving smaller communities in Bainbridge and Summerville. She then practiced for a couple of years in rural Nebraska, where she was one of very few physicians in a small town. That range of experience across community and rural medicine shapes how she approaches every patient. She focuses primarily on adult medicine but also cares for children. She is passionate about partnering with patients to prevent and treat illness and tailors every wellness plan to the individual. Outside the clinic, she spends time with her large family, takes advantage of Georgia's warm weather, and enjoys Lake Lanier and mountain camping.
