Biography
Steven E. Pegalis, Esq. is one of the nation's foremost plaintiffs' medical malpractice trial lawyers and the founder of the Pegalis Law Group. In his career as an advocate for seriously injured victims of negligence, Mr. Pegalis has obtained some of the highest jury verdicts in New York State. Continuing his success over so many years, in 2023 he obtained a $4.6 million settlement for the failure to properly diagnose and treat retinopathy of prematurity, an eye condition common to premature newborn children. Steve settled the case during trial and the infant has also qualified – as a result of the case – for complete medical coverage for life under New York’s Medical Indemnity Fund. In 2021, in a case tried in the midst of the Covid-19 Pandemic, Steve obtained $7.9 million in combined compensation for the family of a deceased husband and father of three in a case involving the tragic aftermath of heart surgery. In 2019 he obtained a mediated settlement in the amount of $8.5 million dollars for a young woman who lost her mother as a result of medical negligence. That same year, he obtained a verdict in the amount of $4.7 million dollars, following his client’s treatment for a brain aneurysm. In 2018, he obtained a $10 million dollar court settlement for a client involving the mismanagement of complex spinal surgery.
Mr. Pegalis is most proud of providing peace of mind, a sense of justice, and financial security to clients. Stacks of photos and thank-you notes from clients’ families are among his most prized possessions. He believes his team’s personal investments in each case are without peer and have resulted in consistent success for clients year after year. He and his firm have worked tirelessly with over 2,000 injured individuals and their families.

Case History
Q&A
Our client Christine Coffey underwent an Onyx brain aneurysm procedure performed by Dr. Henry Woo at Stony Brook University Hospital, his former employer. As a result Ms. Coffey suffered brain damage which caused permanent hemiparesis. Ms. Coffey is unable to return to work, and was left with an impaired ability to raise an infant who is now a young child, due to her hemiparesis.
Ms. Coffey was strongly encouraged to undergo a risky and unnecessary surgery to remove her small “berry” aneurysm, within two months of her visit to the ER complaining of dizziness, and just a few months after the birth of her first child. Dr. Henry Woo failed to provide Ms. Coffey with proper information about the method of treatment. Ms. Coffey was employed at Stony Brook University Hospital.
The jury heard testimony over three weeks before Nassau County Supreme Court Justice Arthur Diamond. Steven Pegalis and James Baydar of Pegalis Law Group, LLC represented Ms. Christine Coffey.
