William N. Brownsberger (born March 21, 1957) is an American politician and the President pro tempore of the Massachusetts Senate[1] representing the Suffolk and Middlesex District[2] which includes his hometown of Belmont, as well as Watertown, the Boston neighborhoods Allston and Brighton, part of Boston's Fenway-Kenmore area, and part of Cambridge. From 2007 to 2012, he was a member of the Massachusetts House of Representatives. He was a candidate for the Democratic nomination in the 2013 special election to succeed Ed Markey in the U.S. House of Representatives.
Brownsberger was born in Boston, Massachusetts, and raised in nearby Watertown. He received a Bachelor of Arts from Harvard College in 1978 and then went on to obtain his Juris Doctor from Harvard Law School in 1985.[3]
He served three terms as a Belmont Selectman and as Massachusetts Assistant Attorney General for six years.
Brownsberger served in the Massachusetts House of Representatives from 2007 to 2012, where he represented the 24th Middlesex district. He was endorsed by the Democratic Socialists of America while seeking reelection in 2010.[4]
A member of the Democratic Party, he ran uncontested in a January 2012 special election to replace Steven Tolman in the Massachusetts Senate, having won a crowded Democratic primary.[5] He was sworn in on January 24, 2012.[6] He was then re-elected in November 2012 to a 2-year term to the 188th General Court.
In 2022, Brownsberger joined Senate President Karen Spilka in opposing unionization effort by Senate staffers, stating "There would be a whole lot of conflict of interest issues if they're working with a union who has its own political agenda. You can't have people serving multiple masters, that’s just not acceptable."[7]
Brownsberger ran unsuccessfully in the 2013 special election to succeed U.S. Representative Ed Markey, who resigned in June 2013 to take a seat in the U.S. Senate.[8]
Brownsberger resides in Belmont, Massachusetts. He is married with three daughters. He is also a marathoner, triathlete, and cyclist. Amidst the Pride parades of June 2023, he came out as bisexual while explaining that his announcement would not change his married lifestyle.[9]
