Over the last 30 years, partner William Kelly has obtained defense verdicts in every downstate county in New York State, including all of the Boroughs of the City of New York. His cases have included products liability actions from snow blowers to stump cutters, as well as defending the Port Authority of New York and New Jersey in several damage trials in 2009 involving the 1993 bombing of the World Trade Center.

During his career, Bill has argued appeals and prevailed in two of the country's most respected appellate venues: the Second Circuit Court of Appeals and the New York Court of Appeals. Bill also lectures for the American Bar Association and the New York State Bar Association, and he has been selected to act as a member of the faculty for the Judicial Institute, providing trial guidance for newly elected Supreme Court judges. He is a frequent presenter on U.S. product liability issues for companies and insurers in China.

Early in his career, Bill served as Managing Attorney in New York City for Transamerica Insurance Company and Royal Sun-Alliance.
