Gary M. Nielsen


Gary Nielsen, Esq. has more than 35 years of experience as a trial and appellate advocate, and has tried medical malpractice cases in New York, Connecticut and North Carolina.

He is a member of the New York State Bar Association, the Nassau County Bar Association, and the American Association for Justice.
