Cooley Dickinson Medical Group is now Mass General Brigham

February 18, 2026

As long-time members of the Mass General Brigham healthcare system, our name change better reflects our connection to the broader network. While our name is new, everything else remains the same — our providers, staff, locations, and strong ties to Cooley Dickinson Hospital, Massachusetts General Hospital, and Brigham and Women’s Hospital. From across the state to Southern New Hampshire, Mass General Brigham practices continue to deliver the same exceptional care to our communities.
