Prisoners' Legal Services

What Prisoners' Legal Services does

Prisoners' Legal Services of Massachusetts (PLS) is a 501(c)-equivalent nonprofit legal services organization founded in 1972 and headquartered in Boston at 50 Federal Street. Its mission is to challenge the carceral system through litigation, advocacy, client counseling, community partnership, and policy outreach, with stated priorities on conditions of confinement, medical and mental health care, racial equity, solitary confinement, and staff-on-prisoner assaults. The organization delivers no technology product; its core deliverables are five service lines — Individual Advocacy, Impact Litigation, Policy Advocacy, Community Engagement, and Systemic Advocacy — supplemented by four specialized projects (Immigrant Detention Conditions Project, Racial Equity in Corrections Initiative, Prison Brutality Project, and Women's Incarceration Conditions and Reentry Project) and internal committees (Healthcare & Disability, Medical Parole, Solitary Confinement).

PLS serves approximately 14,000 incarcerated individuals in Massachusetts Department of Correction facilities and county jails and houses of correction, plus their family members, and a sub-population of immigrants civilly detained in Massachusetts. Intake occurs through Monday afternoon phone lines (1–4 PM), DOC speed dial 9004, mail correspondence, coalition referrals, and pro bono attorney networks. The organization manages approximately 2,000 brief service matters per year — roughly 40% of which involve medical, mental health, and disability issues — and has secured precedent-setting outcomes including access to Hepatitis C medications, reforms at Bridgewater State Hospital, passage of the Criminal Justice Reform Act of 2018, and the May 2025 settlement of Diggs v. Mici.

PLS does not charge clients for services. Revenue is sourced from foundation grants (e.g., RIZE Massachusetts Foundation, Cummings Foundation), individual donations, and potential government/LSC funding, with all revenue figures undisclosed. Pro bono capacity is amplified through co-counsel partnerships with Hogan Lovells, Wilmer Hale, Holland & Knight, the ACLU of Massachusetts, Boston College Law School Civil Rights Clinic, Harvard PLAP, and the Mental Health Legal Advisors Committee, alongside 40+ coalition memberships. The organization transitioned to new executive leadership in 2025 with the appointment of Dave Rini and relocated within its Boston headquarters in February 2026.
