Cohasset is governed on the local level by the open town meeting form of government, and is led by a town manager and a five-member board of selectmen. The current Town Manager is Christopher Senior. Selectmen are elected officials and serve three-year terms led by a chairman in a rotating one-year term. The current Board of Selectmen consists of Kevin McCarthy, Chair, Paul Schubert, Vice-Chair, and Diane Kennedy, Steve Gaumer, and Jack Keniley. The town operates its own police and fire departments, both of which are headquartered near the town center. Emergency services are also provided by the town, with patients taken to the South Shore Hospital in Weymouth. The town's post office is also nearby, just off of the town common. The town's Paul Pratt Memorial Library is located just west of the town center, in what was once a school adjacent to the original library.
