Hennigan's early training in exercise physiology gives him an unusual background among lawyers. That scientific grounding taught him to analyze data and to weigh evidence carefully. Those habits carried over into his legal work. In interviews and client meetings he relies on clear explanations rather than legal jargon.
Throughout his career he has handled a range of matters that arise under Massachusetts law. He works directly with clients and appears in state forums where necessary. His courtroom experience and time spent preparing filings have shaped the way he approaches cases. He favors careful preparation and concise argument.
Hennigan founded Hennigan Law, LLC to serve clients in the region. The firm operates in Massachusetts and provides legal services tailored to state practice. He manages the firm’s work and remains involved in day-to-day matters. Clients can expect direct contact and case-by-case attention.
Outside the office he has maintained ties to the community where he trained and now practices. He has continued to follow developments in Massachusetts jurisprudence and legislative changes that affect local practice. That focus helps him advise clients about how state-level decisions may affect their situations.
