About Sweeney Merrigan Law LLP

Sweeney Merrigan Law derives its name from the large Irish-American family heritage of Attorney Peter M. Merrigan and Attorney J. Tucker Merrigan. Brothers and successful attorneys, Peter and Tucker, have teamed up to earn a strong reputation for providing personal attention to each and every client while consistently obtaining exceptional results. Sweeney Merrigan Law takes pride in advocating and working on behalf of clients throughout all of Massachusetts.

Our practice is focused on prosecuting only catastrophic injury cases. We strive to champion each and every case through verdict, and it is that philosophy that has earned us outstanding results year after year. In just the past three years, we obtained $84.1 million+ in opioid settlements for Massachusetts cities and towns, $12.1 million in a sexual assault case (the largest in the state), $16.9 million for a motor vehicle accident victim which was Massachusetts’ largest single plaintiff tort settlement in 2022, and a record-breaking $20 million dollar New England medical malpractice settlement. We’re eager to serve as your experienced and professional referral partner – in just the past 12 months, we paid out over $6.2 million in referral/co-counsel fees.
