About Us

Matthew Marin has appeared as lead counsel in landmark Rhode Island Supreme Court decisions, including State v. Charlwood and State v. Corcoran, shaping how trial courts handle constitutional and evidentiary questions in criminal cases. Partner Stefanie A. Murphy is admitted in Rhode Island, Connecticut, and Massachusetts and brings federal trial experience to the firm's complex matters.
