Deliberately Different. We came together because we wanted to build a different kind of law firm. We looked around the legal landscape and saw firms following stuffy traditions and preset rules, staying in the lines and abiding by what they were “supposed” to do.

We’re proud to say that’s exactly what we did. When we opened our doors, we were a small group of litigators, lobbyists and corporate lawyers with big ideas. Today, we have 100 lawyers across New England bringing new approaches and innovative solutions to all major fields of law. And as our communities and culture evolve, so do we. We carve out new areas of law where before none existed.
