Ben Zimmermann’s success for clients both in and out of the courtroom is the result of his in-depth understanding of the law and trial practice, his tireless attention to detail in developing the facts of a case, and his commitment to his clients. In his almost two decades of practice, Ben has secured some of the largest personal injury verdicts in Massachusetts for the firm’s clients. In one year alone, Ben obtained two of the ten largest personal injury/wrongful death jury verdicts in Massachusetts, including a $20.6 million verdict against Toys “R” Us for a defective pool slide in a case. The verdict resulted in a decision from Massachusetts’ highest Court, the Supreme Judicial Court, which upheld the award in a landmark opinion in Aleo v. Toys R Us, Inc., 466 Mass. 398 (2013). In 2019, 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 jury verdicts in 2019 and among the largest medical malpractice verdicts in Massachusetts history.

Ben’s practice is 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. He has regularly been recognized in the Top 100 Massachusetts Super Lawyers.

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. In addition to his skills as a trial lawyer, Ben has served as SUGARMAN’s Managing Partner since 2013.

Following a two-week trial in Suffolk County Superior Court in Boston, SUGARMAN Principals Benjamin Zimmermann and David McCormack obtained a $30.55 million jury verdict on behalf of a child who suffered permanent and catastrophic brain injuries during his mother’s labor and delivery at a Boston hospital. The jury agreed that the nurse responsible for monitoring the baby’s heart rate and well-being during labor had failed to ensure that the baby was responding appropriately and that the nurse’s failure to comply with the standard of care resulted in the baby’s severe oxygen deprivation going undetected. The jury awarded damages for both the young boy and his parents.

The jury found both drivers responsible for the incident in issuing their award.
