The Rare Attorney Who Has Sat on Both Sides of the Bench.
Attorney. Judge. Marine Corps Officer. Educator. Shannon Frison brings three decades of distinction to every courtroom she enters, with the intellect, discipline, and presence to command the moment. She is a legal force defined by precision, authority, and an uncompromising commitment to justice.
Shannon Frison’s career is defined by uncommon breadth and unimpeachable credibility. She began as an Assistant District Attorney in Norfolk County, honed her trial practice at Dwyer & Collora, and founded Frison Law Firm, P.C. in Boston in 2007—building a reputation as a formidable advocate long before she took the bench.
For fourteen years, she served as a judge on the Boston Municipal Court and the Massachusetts Superior Court before returning to private practice in 2023. That record—advocate, judge, Marine Corps Major, and legal educator—sets her apart: she understands the law from every critical vantage point and brings that perspective to every case she handles.

Judicial Career
Fourteen Years of Judicial Authority on the Massachusetts Bench
Attorney Frison served on both the Boston Municipal Court and the Massachusetts Superior Court, where she presided over cases that demanded discipline, judgment, and absolute command of the law. Fourteen years on the bench gave her an uncommon vantage point: she has seen how the strongest arguments are tested, how difficult decisions are made, and what it takes to earn credibility before a judge.
That experience carries real weight for clients. It means her advocacy is informed not just by the perspective of a trial lawyer, but by the discernment of a former judge who understands how serious matters are evaluated at the highest level.
