In the summer of 1993, Dr Peter O'Donnell established Harbourside Family Practice, to resurrect the spirit of the small town family doctor. That spirit continues today, over 20 years later. We still follow our original mantra- "An old fashioned Practice with today's treatment and information."

Harbourside Family Practice has held fast to its principles and remains one of only a handful of solo practices remaining in Southern Maine.  The key benefit to a small medical practice over a large practice is access.  

  • same day evaluations

  • comprehensive hour long physical exams

  • thirty minute follow up appointments

  • direct access to nurse or provider

  • opportunity to establish an ongoing relationship with the same practitioner

Meet the Staff
Peter O'Donnell, MD
Family Medicine Physican
Practice Director
Dr. O'Donnell (usually called Dr. Peter) came to maine 25 years ago and opened his practice in Yarmouth with his wife, Mary. Here they brought up their two children who have now moved on to college. Actively engaging the outdoors through mountain biking, hiking and boating, he finds the Maine coast and mountains a great place to pursue a healthy active lifestyle.
Mary, Registered Nurse

Mary grew up and trained in Ireland, but furthered her education at Tufts New England Medical Center where she worked in Intensive Care and Coronary Care prior to moving into family practice. A lover of the outdoors, she is always on the trails either hiking, skiing or on the water paddling her kayak.
