Before joining Epstein Becker Green, Mr. Mongiello was a commercial litigation, white-collar criminal defense, and government investigations attorney at a regional law firm.
Earlier in his career, Mr. Mongiello served as a New Jersey State Deputy Attorney General in the Appellate Bureau of the Division of Criminal Justice, where he represented the State before the Appellate Division and New Jersey Supreme Court on matters of statewide importance. In that capacity, he successfully defended against a constitutional challenge in the New Jersey Supreme Court to the state’s judicial recall statute, which authorizes retired judges over the age of 70 to temporarily return to service. He also received the 2015 Attorney General’s Award for Excellence in Trial Litigation for his role in a successful public corruption prosecution by twice securing reversals on interlocutory appeals of the trial court’s rulings, including one reversal on an emergent basis during trial to prevent the court from issuing its proposed jury charge.
During law school, Mr. Mongiello participated in Seton Hall Law School’s Impact Litigation Clinic, where he briefed and argued an appeal before the U.S. Court of Appeals for the Second Circuit and obtained a reversal of the district court’s order on behalf of his client. He also interned at the U.S. Department of Education, Office for Civil Rights, where he investigated claims of race, sex, age, and disability discrimination in educational institutions.
Mr. Mongiello completed clerkships with the Honorable Anne M. Patterson of the New Jersey Supreme Court and the Honorable Mary L. Cooper of the U.S. District Court for the District of New Jersey. In addition, the New Jersey Supreme Court has appointed Mr. Mongiello to serve as a member of the District VI (Hudson County) Ethics Committee.
