William James O'Mahony

Following his graduation from the University of Notre Dame, William J. O’Mahony began his legal career in South Bend, Indiana, where he handled the defense of insured policyholders in product liability, general liability and employment discrimination claims and also represented insurance carriers in insurance coverage and bad faith litigation. In 1996, Bill returned to his native New York and became an associate with a large national law firm where he was responsible for the investigation and defense/prosecution of complex corporate and commercial claims, including contract, unfair competition, trade secret and restrictive covenant litigation, corporate dissolution proceedings, employment litigation, and the defense of professional liability and municipal liability claims. Thereafter, he became a partner with a boutique litigation firm, where he represented individuals and corporations in insurance coverage disputes, and in corporate and commercial litigation. Bill’s practice encompasses all aspects of litigation and consulting in Paneth & O’Mahony’s insurance and commercial litigation practice groups. He has lectured and authored instructional materials on insurance law for the New York State Bar Association and other continuing legal education programs. Bill has also served as a guest lecturer at Touro Law School concerning law practice management and risk management for law firms. Bill has been rated “AV Preeminent” by Martindale Hubbell, the highest possible rating in both legal ability and ethical standards. He also has been inducted as a lifetime member of the Multi-Million Dollar Advocates Forum, which acknowledges excellence in advocacy by lawyers throughout the United States and is limited to attorneys who have won multi-million dollar verdicts, awards or settlements. Bill is also a former member of the New York State Bar Association’s Committee on Professional Discipline.
