Massachusetts Treatment Center Overview
The Massachusetts Treatment Center, often abbreviated MTC, is operated by the Massachusetts Department of Correction at 30 Administration Road in Bridgewater. The Mass.gov description identifies it as a medium-security facility that separately houses criminally sentenced male inmates identified as sex offenders and people civilly committed as sexually dangerous persons. It is part of Plymouth County's broader custody landscape, but it is not the Plymouth County Correctional Facility and is not searched through a county jail roster.
DOC annual-report material says MTC opened in 1986, expanded in 1997, and was initially ACA-accredited in 1997. The report describes MTC's mission as assessment and evidence-based treatment addressing risk factors of sexual offending. Its statutory backbone includes sexually dangerous person proceedings under M.G.L. c. 123A, Section 14, while criminally sentenced inmates remain in DOC custody under prison rules.
The practical lookup rule is simple: use the state DOC route. A person at MTC may have a criminal sentence, a civil sexually dangerous person commitment, or a temporary civil commitment, and those categories are separate from ordinary county pretrial detention after arrest.
Massachusetts Treatment Center Capacity and Population
The DOC FY2023 annual-report figures list MTC with operational capacity of 680, average daily population of 500, and a January 1, 2024 population of 472. The January 1, 2024 population breakdown was 359 criminally sentenced commitments, 97 sexually dangerous persons, and 16 temporary civil commitments. These are DOC reporting figures, not a live roster count.
| Custody Category | Jan. 1, 2024 Count | Source Context |
|---|---|---|
| Criminally sentenced commitments | 359 | DOC FY2023 annual report |
| Sexually dangerous persons | 97 | DOC FY2023 annual report |
| Temporary civil commitments | 16 | DOC FY2023 annual report |
How to Look Up an Inmate at Massachusetts Treatment Center
For MTC, start with the Mass.gov Find an inmate in a Massachusetts prison page and the Massachusetts VINELink portal. VINELink is the public custody-status and notification channel Mass.gov directs users to for DOC facilities. It can help confirm custody or notification status, but it should not be treated as a complete sentence-computation, treatment, parole, or court file.
- Open the Mass.gov DOC inmate-lookup instructions and proceed to Massachusetts VINELink.
- Search by exact name, and use a DOC or case identifier if one is available from the court, attorney, or family paperwork.
- Check whether the result identifies Massachusetts Treatment Center or another DOC location.
- Review custody-status information and register for notifications only if that is appropriate for the searcher's role.
- Call MTC before relying on any result for visiting, release timing, mail, or urgent facility contact.
Lookup distinction: MTC is a DOC medium-security treatment center. Use DOC/VINELink, not the Plymouth County jail roster, to search for someone held there.
Official Facility Source
The official Mass.gov Massachusetts Treatment Center page is the facility source matched to the image below and should be used for current address, phone, and facility-description checks.
The Mass.gov page supports the main search distinction: MTC is a DOC institution for sex-offender and sexually dangerous person treatment populations, so county jail booking procedures do not apply.
Massachusetts Treatment Center Address and Contact
Use MTC directly for facility questions about visits, mail, and contact procedures. For public records, Massachusetts law separates the agency that created or received a record from other agencies that may not hold it. A custody lookup, a court docket, a DOC facility record, and a prosecution record can all live in different systems. M.G.L. c. 66, Section 10 supplies the public-records request framework, while CORI, privacy, investigatory, medical, security, and impoundment limits can restrict release.

Visiting Someone at Massachusetts Treatment Center
MTC visitation follows DOC facility rules, not the Plymouth County Correctional Facility visitor booklet. MASAC, MTC, OCCC, and BSH are state DOC facilities, so visitor approval and scheduling should follow DOC facility procedures and statewide DOC visitor application channels. Because MTC houses sentenced and civilly committed treatment populations separately, call the facility or check DOC instructions before assuming a visit is available.
| Visitation Item | MTC Route | Important Distinction |
|---|---|---|
| Approval | Use DOC visitor approval procedures | PCCF county preapproval forms do not govern MTC visits. |
| Scheduling | Confirm through MTC/DOC before traveling | No fixed MTC schedule was available in the official source material used here. |
| Population-specific limits | Ask about the person's custody category | Criminally sentenced, SDP, and temporary civil commitments may have different controls. |
| Identification and screening | Follow DOC entry instructions | Facility security rules apply at the Bridgewater site. |
Mail, Phone, and Money at Massachusetts Treatment Center
Mail, phone, and money rules at MTC are DOC facility rules. Do not apply PCCF's personal-mail scanning center, county kiosk, or Access Corrections details to MTC unless DOC separately says to use that route. For privileged mail, treatment-related correspondence, property, and account deposits, use the current DOC or MTC instruction and include the identifying information the facility requires.
| Service | Use for MTC |
|---|---|
| Personal mail | Confirm the current DOC/MTC format with the facility before sending. |
| Legal mail | Use DOC privileged-mail instructions and include the inmate's identifying information. |
| Phone contact | Ask MTC about approved calling procedures and any category-specific restrictions. |
| Money or property | Use only DOC-approved account or property channels for MTC. |
Reception, Classification, and Treatment Status at MTC
MTC intake is not ordinary street-arrest booking. Criminally sentenced men identified as sex offenders enter DOC custody after conviction and sentencing, while sexually dangerous person and temporary civil commitments are governed by Chapter 123A procedures. The DOC annual-report description emphasizes assessment and evidence-based treatment that addresses risk factors for sexual offending in a correctional environment and after release.
Search results may not explain the full legal reason someone is at MTC. Use MassCourts or the clerk for court events, DOC/VINELink for custody status, and MTC for practical contact and facility procedure questions. Treatment, clinical, security, CORI, and impounded records may be unavailable to the general public.
About Massachusetts Treatment Center
MTC sits in the Bridgewater correctional cluster near Old Colony Correctional Center and Bridgewater State Hospital, but it is a separate DOC institution with its own population and mission. MTC's reported FY2023 annual cost per person was $104,334, and the facility had 472 people on January 1, 2024, below its 680 operational-capacity figure.
Recent news should be handled carefully. WHDH reported on September 30, 2024 that an inmate died after an assault at MTC and that DOC, State Police, and the Plymouth County District Attorney were investigating. That is state-prison news, not PCCF news, and it should not be used to describe ordinary visitation or lookup rules.
Confirm first: Verify DOC custody status, visiting approval, and mail instructions with MTC before traveling to Administration Road.
