Founding Partner Matthew T. Marin and Co-Managing Partner Stefanie A. Murphy will continue to lead the firm, bringing nearly 40 years of combined high-stakes trial experience. Streamlining its partnership structure allows the firm to sharpen its focus on client relationships, courtroom performance, and exceptional case results—spotlighting the Marin–Murphy collaboration that has driven major wins, including multiple criminal not‐guilty jury verdicts and more than $15 million recovered for clients in 2025 alone.
“After an extraordinary year, we are investing in the next chapter of our practice and reaffirming our core identity as trial lawyers,” said Founding Partner Matthew Marin. “Stefanie and I have always shared one vision: to stand with the accused when the stakes are highest and to ensure no one faces the justice system alone. That mission remains unchanged. At the same time, we continue to deliver life-changing results for the seriously injured in personal injury and mass tort matters. Under the Marin & Murphy name, we are more focused, more aggressive, and more committed than ever to winning for our clients.”

About Attorney Stefanie A. Murphy
Co-Managing Partner Stefanie A. Murphy, one of Rhode Island’s most respected criminal defense attorneys, brings a deep command of negotiation, trial strategy, and courtroom execution. A graduate of Roger Williams University School of Law, she represents clients in Rhode Island, Connecticut, and Massachusetts. Murphy has been recognized by Super Lawyers as both a “Rising Star” and a “Super Lawyer” every year from 2012–2025, and she is a member of the National College for DUI Defense and the National Association of Criminal Defense Lawyers. Her practice spans DUI/DWI defense, domestic violence, drug offenses, white-collar crime, federal cases, and complex felonies.
In October 2024, Murphy led the defense in a high-profile first-degree murder trial, securing a full acquittal after three hours of jury deliberation in a case marked by heightened emotions and community tension. In her words:
“This was a case centered around a lot of emotions in the community and facts. The circumstances were disheartening and life-shattering for many involved. But at the end of the day, it’s up to our team to provide unwavering support, seek justice, and ultimately bring closure to those affected. It’s our job to meticulously weed through the emotions, unveil the facts, and champion the cause of justice.”
