Ben Zimmermann’s success for his clients stems from his proven record at trial. In his over twenty years of practice, Ben has secured some of the largest personal injury verdicts in Massachusetts, including seven and eight figure verdicts in medical malpractice, construction site, defective products, motor vehicle and airline negligence cases. In one year alone, Ben obtained two of the largest personal injury/wrongful death jury verdicts in Massachusetts, including a $20.6 million wrongful death verdict against Toys “R” Us for a defective pool slide – an award which was upheld by the Massachusetts Supreme Judicial Court in its landmark opinion, Aleo v. Toys “R” Us, Inc. Ben and his partner David McCormack obtained a $30.55 million medical malpractice verdict for the family of a child injured at birth, one of the largest medical malpractice verdicts in Massachusetts history. With results like these, Ben has routinely been named as one of the Top 100 Massachusetts Super Lawyers, and has been inducted as a Fellow of both the American College of Trial Lawyers and International Academy of Trial Lawyers.

Ben’s career and practice has been dedicated to the litigation and trial of personal injury cases, with an emphasis in the areas of defective products, medical malpractice, construction site accidents, and premises liability. He has also litigated, tried, and handled the appeal of cases aimed at obtaining insurance coverage for injured clients where coverage is disputed. Ben is a member of numerous bar organizations and committees, and is a regular lecturer at continuing legal education programs and to area law students.

After graduating from Fordham University School of law in Manhattan in 1999, Ben took a position in the litigation department of a large firm in New York, but quickly realized that he wanted to represent individuals in the courtroom. Presented with the opportunity, Ben joined SUGARMAN as an associate in 2000 and became a principal of the firm in 2007. Ben has served as SUGARMAN’s Managing Partner since 2013.
