Dr. Peter Witham specializes in internal medicine. His medical interests and expertise include the evaluation and care of patients with multiple ongoing medical conditions and the care of older patients. He believes in establishing long term relationships between patient and providers leads to the best patient care. “I came to MDI to work with a group of people who are dedicated to caring for both their patients and the community as a whole,” he says.

Outside of work, Dr. Witham enjoys photography, hiking, baking, and spending time with his wife and their Bernese Mountain dogs. He and his wife were originally introduced to MDI when they visited the Appalachian Mountain Club on Echo Lake for a camping trip in the early 90s, and they still go every year.
