About me

I am an experienced litigator and problem solver focusing on the areas of business litigation (e.g., contract disputes, business torts), employment law, governmental law matters (including government investigations), and administrative law. Wide-ranging experience advising and representing business organizations, non-profit organizations, trade associations, private individuals, and state and municipal governmental agencies, authorities, and officials. In addition, I provide advice and representation to private entities, individuals, and governmental bodies on matters of compliance with federal and state civil rights and civil liberties laws, government ethics, public records laws, election laws, administrative agency rule-making, and other government operations. I am also an experienced appellate attorney having handled more than 100 cases before the Massachusetts appellate courts and Federal appellate courts.
