Kevin M. Cloutier is a Boston-based trial attorney whose practice focuses on personal injury, criminal defense, and zoning and development matters. He represents individuals and businesses facing serious legal issues that demand disciplined preparation, sound judgment, and effective courtroom advocacy.
Attorney Cloutier brings a broad litigation background to every case he handles — including extensive experience as a former prosecutor, trial lawyer, and military officer — and personally represents each client from intake through resolution.
Prosecutorial and Trial Experience
Before founding The Cloutier Law Firm, Attorney Cloutier served for six years as an Assistant District Attorney in the Suffolk County District Attorney’s Office. During that time, he prosecuted thousands of cases in the Boston Municipal Court divisions of Dorchester, South Boston, Charlestown, East Boston, and Brighton, and later in the Superior Court as a member of the Major Felony Unit.
His prosecutorial work included cases involving:
- Violent offenses
- Domestic violence
- Narcotics distribution and possession
- Firearms and weapons charges
- Operating under the influence
- Larceny and financial crimes
- Sexual assault and indecent assault and battery
This experience gives Attorney Cloutier a deep understanding of how criminal cases are investigated, charged, negotiated, and tried — insight he now uses to defend individuals facing the full prosecution.
Early Legal Career
Attorney Cloutier’s legal career began at the Boston Police Department, where he worked in the Legal Advisor’s Office during the summer of 2004. He provided legal research and courtroom preparation on civil-rights and security issues related to the Democratic National Convention held in Boston that year — a complex, high-stakes environment requiring careful coordination between law enforcement and constitutional protections.
During law school, Attorney Cloutier also worked as a paralegal at Cloutier & Cassella, LLC, a respected general litigation firm in Old Saybrook, Connecticut, founded and managed by his late father, Thomas A. Cloutier.
Legal Legacy and Professional Values
Thomas A. Cloutier practiced law for over thirty years and served as President of the Connecticut Trial Lawyers Association. His firm represented generations of families and businesses along the Connecticut shoreline and became known for principled advocacy and long-standing client relationships.
Attorney Cloutier applies the same professional and ethical standards to his own practice today — emphasizing preparation, honesty, and accountability to clients whose cases often involve life-altering consequences.
Judgment Under Pressure

Attorney Cloutier is a U.S. Army Veteran of the Iraq War, where he commanded a multi-functional intelligence team in support of the 1-8 Infantry Battalion, Third Brigade, Fourth Infantry Division. Following his deployment, he took command of Alpha Company, 325th Military Intelligence Battalion.
He retired from the Army in 2011 with the rank of Captain.
His military service continues to inform his legal practice — particularly in high-pressure situations requiring calm analysis, decisive action, and responsibility for outcomes.
Attorney Cloutier lives in West Roxbury with his wife and two sons.
