Management Committee

Lauren Weitzen is a determined advocate and skilled criminal defense litigator. She represents individuals facing investigations and charges in state courts across Massachusetts. With significant courtroom and trial experience, her extensive knowledge of criminal law and commitment to and zeal for justice enables her to provide her clients with strong, unwavering, and effective advocacy. Lauren’s experience and familiarity with the often-evolving law allows her to recognize the strengths and weaknesses of available defenses and to advance particular case strategies on behalf of her clients. She has represented clients charged with cases ranging from drug offenses, domestic violence, sex crimes, property offenses, to motor vehicle offenses.

Lauren also advises clients on how to minimize their contact with the criminal justice system, including guiding them through police investigations, Clerk Magistrate hearings, and pre-trial diversion options.

Since the numerous changes implemented from the recent Criminal Justice Reform Act, Lauren represents individuals seeking to seal or expunge prior criminal records (G.L. c. 276 § 100A-K). Her practice also includes various other collateral criminal matters including obtaining or defending against restraining orders (G.L. c. 209A) and harassment prevention orders (G.L. c. 258E), and matters involving the Sex Offender Registry Board.

Prior to joining Lawson & Weitzen in 2014, Lauren was Staff Attorney and a Supervising Attorney with the Committee for Public Counsel Services Public Defender Division, where she gained invaluable trial experience and an intimate knowledge about the inner workings of our criminal justice system. Lauren volunteers with the Suffolk Law School Alumni Mentor Program and as a judge with the Massachusetts Bar Association’s Mock Trial Competition. She remains a bar advocate, accepting court appointed cases for indigent defendants, with the Middlesex County Bar Advocate Program.

Lauren actively supports the American Civil Liberties of Massachusetts and is a member of the event committee for its annual Bill of Rights dinner. She lives in Needham with her husband and two young children.
