Who Represents Dartmouth
Dartmouth is not split anywhere, which makes this simpler than it is for a lot of Massachusetts towns. One state representative, one state senator and one member of Congress speak for the entire town, so the person who answers for your street is the same person who answers for every other street in Dartmouth. The Commonwealth’s two U.S. senators represent the whole state, Dartmouth included. Four names, and they cover everything from a pothole bylaw to a federal fisheries rule.
State Senator
Second Bristol and Plymouth District · Democrat
Mark C. Montigny
State House: Room 312-C · (617) 722-1440
Email: mark.montigny@masenate.gov
Senator Montigny’s district is built around New Bedford harbor, which means the same senator who votes on your school funding also votes on the fishing industry that shaped this coast. Dartmouth sits in the district whole, so there is no precinct line to check before you write to him.
State Representative
All of Dartmouth sits in the 9th Bristol House district, which the town shares with part of New Bedford. One representative speaks for the whole town.
9th Bristol District · Democrat
Christopher M. Markey
State House: Room 276 · (617) 722-2676
Email: christopher.markey@mahouse.gov
A state representative files bills, votes the state budget, and can chase a state agency on a constituent’s behalf, which is often the fastest use of the office. His district office and his State House office both take calls from Dartmouth residents.
In Washington
All of Dartmouth sits in the 9th Congressional District, one of the largest in the state, running from New Bedford out across Cape Cod and the Islands. Massachusetts is represented in the U.S. Senate by Elizabeth Warren, the senior senator, and Edward J. Markey, the junior senator, both Democrats. Note that the junior U.S. senator and Dartmouth’s state representative share a surname and are two different people.
9th Congressional District · Democrat
William R. Keating
Washington: 2372 Rayburn House Office Building · 202-225-3111
