Biography | Dennis Sullivan


Dennis began his career in public service fighting for the City’s smallest residents. As a School Committee Member and former Chairman, he championed full-time nurses, low class sizes and the building of three new schools. Somerville continues to be the only school system in the state that offers free full day pre-kindergarten and free kindergarten. The Healey School, the Kennedy School and the Capuano Early Childhood Center were all built with 90% reimbursement from the state, saving Somerville taxpayers millions of dollars.

Elected to the Board of Alderman in November 2003 Dennis is one of four citywide Aldermen. He currently serves as the Chairman of the Committee on Licensing and Permits.

Dennis is a Sergeant with the Department of Correction, assigned to the Employee Assistance Program, where he assists officers and personnel with stress, personal and medical issues.

Dennis grew up in East Somerville. His mother, Hanoria, emigrated from Ireland at age 17 and met his late father, Joe, an MBTA bus driver and proud member of the Carmen’s Union for over 40 years.

For six years, Dennis was a Combat Medic in the Massachusetts National Guard located at the Highland Avenue Armory, and he continues to be a member of American Legion Post #19. Dennis is a graduate of Saint Clement High School and Curry College. He received a certificate from the Kennedy School of Government Rappaport Institute on Municipal Governance and Public Policy Program.

Dennis has volunteered for Somerville Little League as a coach and umpire and has umpired high school Babe Ruth and junior college baseball. An avid golfer, most spring weekends you’ll find him hitting the local links – that is if office hours are not in session!

For several years, Dennis has played “Santa Clause” for the annual holiday tree lighting at City Hall. He even arrives on top of the fire engine!

Dennis and his wife, Melissa, have a daughter Jaclyn Rose, who was born in 2014. They live with their dog Nilla on Ten Hills Road in ward four.
