A partner in Riker Danzig's commercial litigation group, Marc D'Angiolillo has considerable experience in complex commercial litigation through trial and at the appellate level.

Known for his skill in complex multi-party litigation, Marc has handled numerous large construction defect actions. Notably, he successfully represented the Hertz Corporation in connection with the collapse of its massive multi-story parking garage at Newark Liberty International Airport. He also recovered over 1.2 million dollars for the West Morris Regional High School District Board of Education in a construction defect action.

Marc also successfully represented the co-executor of an over 25 million dollar estate in a highly-publicized estate litigation. In the aftermath of the unsolved murder of the testator, a prominent real estate developer who was shot and killed while asleep in his bed in his Clinton Township mansion, Marc effected the removal of a co-executor who was himself a suspect in the murder. Marc also recovered over 1 million dollars which had been misappropriated from the estate by the co-executor.

In another closely watched case involving a 198 million dollar development proposal, Marc successfully represented the Borough of Sayreville at trial and through appeal against a developer's challenge to the Borough's amended zoning ordinance.

In another high profile matter, Marc successfully represented United Steel & Wire Company in a massive toxic tort class action in Camden County. There, plaintiffs sought to certify a medical monitoring class of every person who used or consumed Camden drinking water for a period of 180 days or more between 1974 and 1998. Marc served as one of the lead defense attorneys who successfully opposed class certification and obtained the dismissal of the underlying action on statute of limitations grounds.

Marc also successfully represented a national window retailer on its claims for trademark infringement and unfair competition on the Internet in one of the first known "meta-tagging" cases in the United States.

Marc was a judicial intern to U.S. District Judge Alfred M. Wolin in the District of New Jersey. He was the first recipient of the Joseph P. Miele Scholarship at Seton Hall University School of Law and served as a trustee of the Scholarship Foundation. He is also the Vice-Chairman of the Partnership for a Drug Free New Jersey.
