The Massachusetts Treatment Center is located within the Bridgewater Correctional Complex and is a unique facility due to having a population of civilly committed Sexually Dangerous Persons as well as state prison inmates identified as sex offenders. Each population is located within separate areas of the facility.
The civil commitment process is determined by General Law Chapter 123A.
The Mission of the Massachusetts Treatment Center is to promote public safety through the responsible management of criminal and civil commitments while providing a comprehensive and effective sex offender treatment program.
