Jeffrey Mongiello focuses his practice on commercial litigation and white collar criminal defense in state and federal courts. He also has extensive experience handling appellate litigation.
Prior to joining Connell Foley, Jeff served as a Deputy Attorney General in the Appellate Bureau of the New Jersey Attorney General’s Office – Division of Criminal Justice, where he represented the State before the Appellate Division and Supreme Court on matters of statewide importance. In that capacity, he successfully defended New Jersey’s judicial recall statute, which authorizes retired judges over the age of 70 to temporarily return to service, against a constitutional challenge in the Supreme Court. He received the 2015 Attorney General’s Award for Excellence in Trial Litigation for his role in a successful public corruption prosecution by twice securing reversal of the trial court’s rulings on interlocutory appeals, including once on an emergent basis during trial to prevent the court from issuing its proposed jury charge.
During law school, Jeff participated in Seton Hall Law School’s Impact Litigation Clinic, where he briefed and argued an appeal before the Second Circuit and obtained reversal of the District Court’s order on behalf of his client.
Jeff completed clerkships with the Honorable Anne M. Patterson of the New Jersey Supreme Court and the Honorable Mary L. Cooper of the United States District Court for the District of New Jersey.
The New Jersey Supreme Court has appointed Jeff to serve as a member of the District VI (Hudson County) Ethics Committee.
