A medium-security men's facility in Bridgewater that provides treatment for men with sex offenses and holds men civilly committed as sexually dangerous persons, part of the Bridgewater complex.

Statewide rules that apply at every Massachusetts state prison

These rules are set by Massachusetts DOC and apply at every unit. The full list — including all permitted and prohibited items and the approval process — is in Visiting in Massachusetts.

Dress code

Dress modestly and avoid clothing that resembles what incarcerated people or staff wear; no revealing, sheer, or provocative clothing.
Each prison publishes its own visiting dress code and item limits — confirm them with the facility before traveling, since a visitor who is dressed out of code can be turned away.

ID: Every visitor must be on the incarcerated person's approved visitor list and submit a visitor application to the prison; the Department runs a criminal-history check before approval. Adults must show a valid government-issued photo ID at each visit. The incarcerated person can add new visitors only during set windows (the first 15 days of March, July, and November).
What to bring: Bring only a photo ID and what the specific facility allows in the visiting room — phones and bags are not permitted. Money for the person is sent through Access Corrections, never handed over at a visit; confirm each facility's item and locker rules before visiting.
Scheduling: Massachusetts has no statewide online visit scheduler — each prison schedules visits by phone and sets its own days and hours, so call the facility to arrange a visit and confirm the schedule. A newly committed person is held at a reception center first — Souza-Baranowski for men, MCI-Framingham for women — before transfer to a permanent prison.

Overview

The Massachusetts Treatment Center, on Administration Road in Bridgewater, is a medium-security DOC facility for men. It provides treatment for men serving sentences for sex offenses, and it also holds men who have been civilly committed as “sexually dangerous persons” under Massachusetts law (Chapter 123A) — that is, held for treatment beyond a criminal sentence. The Treatment Center is one of several DOC facilities at the Bridgewater complex, alongside the Old Colony Correctional Center and Bridgewater State Hospital, so confirm which one holds the person before traveling.
