Gary Nielsen is a trial and appellate advocate with 35 years of experience. He has litigated medical malpractice cases in New York, Connecticut and North Carolina. He is celebrating his 20th anniversary on the gold standard of attorney rating systems- Martindale-Hubbell. Since 1999, he has maintained the highest rating “AV Preeminent” from Martindale-Hubbell, in peer recognition of his legal ability, ethics, judgment and experience. He has represented hundreds of patients who were victims of medical errors and has obtained many million dollar settlements for injured plaintiffs. Previously, Mr. Nielsen successfully represented plaintiffs and defendants in employment discrimination, product liability, legal malpractice and fraud claims. He has been recognized on the New York Metro Area Super Lawyers® List among only 5% of all U.S. lawyers, and has been profiled as a prominent medical malpractice lawyer in the Long Island Business News.
