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 and in 2023 selected to Lawdragon’s 500 Leading Plaintiff Consumer 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 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.

Significant Cases

medical malpractice SUGARMAN obtains one of the largest reported medical malpractice settlements in Massachusetts for 2022

Substantial recovery in medical malpractice for a 14-year-old girl and her parents when, following removal of a benign brain tumor as a toddler, several doctors at a major Boston hospital failed for years to order any imaging studies to monitor the patient for recurrence of a brain tumor. While going without an MRI for over four years, the tumor recurred in the patient and grew undetected, resulting in permanent neurological injury requiring lifelong medical care. The case, which was one of the top 3 reported medical malpractice settlements in Massachusetts for 2022, resolved just before trial after SUGARMAN attorneys successfully limited the scope of the testimony of the defendant physicians’ medical experts at trial.

medical malpractice Verdict in labor and delivery medical malpractice case

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.

medical malpractice Jury verdict for Massachusetts woman injured on operating table

An Essex County jury sitting in Newburyport rendered a verdict in favor of a 42-year-old woman who suffered significant neck injuries at a hospital in Lynn, MA, after being positioned on an operating room table for routine surgery. After she was anesthetized and medically paralyzed, her unsecured head fell off the table resulting in permanent nerve damage to her neck.

medical malpractice Wrongful death - Complications of colonoscopy

Settlement of medical malpractice lawsuit for widow and family of middle-aged man who became brain damaged and ultimately died as a result of a ruptured spleen suffered during a colonoscopy. While the complication is rare, it is known to occur. The medical negligence case/wrongful death case was brought for failure to recognize signs of splenic rupture and bleeding in the hours following the procedure.

construction Wrongful death following crush injuries to forklift operator

Pre-trial settlement on behalf of children of a middle-aged temporary worker who was crushed to death between the forklift he was operating and a metal shelving unit in a South Shore warehouse where he had been assigned to work by his staffing agency.

construction Jury verdict for worker who fell through unguarded opening at construction site

A Middlesex County jury returned a 7-figure verdict on behalf of worker injured after falling more than 20 feet through an unguarded opening on a construction project at the Natick Mall. The defendant general contractor had claimed that the opening had been guarded and that the plaintiff had somehow gained access through it without the general contractor's knowledge. Through painstaking investigation and work immediately following the accident, Sugarman's attorneys were able to prove to the jury at trial that the general contractor had made up the story and had added guarding after the accident. The case was one of 10 largest jury verdicts reported in Massachusetts in 2011.
