Carolyn O’Donnell, M.D.


Carolyn O’Donnell grew up in Massachusetts, and loves the beauty of New England. She adores children, and takes immense joy in watching her patients grow, learn and thrive. She treats all patients the same way she would her own children who are also patients at Acton Medical. Dr. O’Donnell takes her position as a pediatrician and child advocate seriously, and believes strongly in the benefit of vaccinations toward keeping children healthy and safe. She believes every child is unique, special and precious.

Dr. O’Donnell went to college at UMass Amherst, trained at UMass Medical School, and continued there for residency. She began practicing at Acton Medical in 2010, and plans to stay “forever.” In her free time she enjoys traveling, playing outside with her husband and two kids, reading, and crocheting. One of Carolyn’s favorite phrases is; “The only person you are destined to become is the person you decide to be.”
