About Michael
Michael Lesser built his legal foundation at Brandeis University, where he completed his undergraduate studies in 1992, and at Boston University School of Law, earning his J.D. in 1995. He entered the profession at a time of change in the legal landscape. Those academic years prepared him for courtroom work and appellate practice that would follow.
Soon after law school, Lesser began work at Thornton Law Office LLP in 1995. He has remained associated with that firm since then. Over decades at the same office, he has handled a steady stream of matters that required courtroom readiness and procedural precision. His career path shows continuity rather than frequent moves between firms.
Lesser is admitted to practice in Massachusetts and before the U.S. Court of Appeals for the First Circuit. Those admissions shape the geography and type of matters he takes on. He is a member of the American Bar Association and the American Association for Justice. He also belongs to Taxpayers Against Fraud. Those memberships place him among attorneys who engage in litigation and advocacy on both individual and public-interest fronts.
Colleagues describe him as someone who prefers to let case records speak for themselves. He has worked on cases that proceeded in trial courts and on matters that required appellate briefing. Over time he has combined trial practice with appellate appearances, handling procedural and substantive challenges that arise in both settings. That combination has made him familiar with the mechanics of preparing a record for appeal as well as the demands of presenting arguments to juries or judges at trial.
Outside the courtroom, Lesser’s long tenure at a single firm has meant steady involvement in local legal circles. He maintains active memberships in professional organizations and has taken part in events and continuing legal education opportunities offered by those groups. He remains based at Thornton Law Office LLP, working on litigation and appellate matters in Massachusetts and in the First Circuit. His current practice focuses on litigation and appellate work in those jurisdictions.
