Matthew T. Marin is the Founding Partner of Marin & Murphy Law Firm, a nationally recognized plaintiff litigation firm concentrating in mass tort, pharmaceutical and medical device litigation, environmental and toxic tort contamination, product liability, and catastrophic personal injury.
Mr. Marin earned his J.D. from Roger Williams University School of Law (2008) and simultaneously obtained an M.B.A. from the University of Rhode Island (2008) — a rare dual-degree combination that gives him unique insight into the corporate decision-making he now challenges in court. He received his B.A. in Management, magna cum laude, from Clark University (2004), where he was awarded the Morton H. and Vivian B. Sigel Undergraduate Management Award and elected to Phi Beta Kappa.
Licensed in South Carolina (Bar No. 102771), Rhode Island (Bar No. 7934), Connecticut (Bar No. 430019), and Massachusetts (Bar No. 672462), Mr. Marin maintains an active national practice. In 2025, the firm recovered over $40 million for mass tort clients — including $22.95 million for cryptocurrency fraud victims, $14.5 million in PFAS water contamination settlements as part of the landmark $15 billion PFAS class settlement, and $1.575 million for Astroworld tragedy survivors. Active dockets include Depo-Provera meningioma, ethylene oxide exposure, and Dupixent CTCL litigation nationwide. He also represents more than 500 individuals in PFAS personal injury litigation.
As founding attorney, Mr. Marin established significant Rhode Island criminal defense precedent. In State ex rel. Coventry Police Dep't v. Charlwood, No. 17-388 (R.I. 2020), the Rhode Island Supreme Court — Chief Justice Suttell authoring — established record sealing rights under R.I.G.L. §12-1-12. In State v. DiSalvo, No. 18-0273 (R.I. Super. 2020), he secured dismissal of drug trafficking charges generating three statutory holdings under the Good Samaritan Overdose Prevention Act. In State v. Corcoran, No. 20-121 (R.I. 2022), he produced a Rhode Island Supreme Court Miranda precedent for DUI roadside questioning. All three decisions were covered in Rhode Island Lawyers Weekly.
Mr. Marin's peer-reviewed honors include selection to Super Lawyers (2014–present), National Trial Lawyers Top 100, Martindale-Hubbell AV Preeminent rating, Martindale-Hubbell Client Champion Platinum Award (2026), and the Avvo Clients' Choice Award. He is a two-time speaker at Mass Torts Made Perfect (October 2024 & 2025) — the nation's premier mass tort litigation conference — and an active member of the American Association for Justice (Environmental & Toxic Tort Litigation Group and Pharmaceutical & Medical Device Litigation Group).
Representative results include over $40 million recovered in 2025, $400,000 (2024 bicycle accident), $250,000 (2024 golf cart injury), and numerous six-figure settlements in motor vehicle and premises liability matters.
Marin & Murphy Law Firm has earned 440 five-star Google reviews and an Avvo 10.0 Superb Rating with 148 Avvo reviews. All personal injury and mass tort cases are handled on a contingency fee basis — no fees unless we recover.
Mr. Marin and his wife Danielle reside in the Charleston area with their two sons and golden retriever.
