Leadership at Martin's Point

David Howes, MD
President and Chief Executive Officer

Dr. David Howes began his medical career as a family physician serving the small, rural fishing community of Stonington, Maine. This experience taught him the importance of engaging patients in their own healthcare, helping to improve health outcomes and better manage the cost of care. He brought this philosophy to Martin’s Point Health Care in 1989 as a primary care physician and now serves as the President and CEO, a position he has held since 1996. Deeply committed to the Martin’s Point mission, David has dedicated his career to creating a healthier community.

David is involved with numerous health care and business organizations and was inducted into the Junior Achievement Business Hall of Fame in 2019. He currently presides as Chair of the Board of Directors for the Alliance of Community Health Plans and serves on the Boards of the US Family Health Plan Alliance and the Maine Guaranteed Access Reinsurance Association. He is also a current member of the American College of Physician Executives and the American Academy of Family Practice.

David earned his medical degree from Dartmouth Medical School in Hanover, New Hampshire, and served residencies at the Dartmouth-Hitchcock Medical Center, the Medical Center Hospital of Vermont in Burlington, and the Eastern Maine Medical Center in Bangor Maine. In 2020, David was granted an Honorary Degree in Humane Letters from the University of Southern Maine.

Outside of work, David enjoys spending time with his children—who inspire world travel—as well as many outdoor activities including sailing, hiking and biking.
