Mariellen Dugan

Director, Commercial & Criminal Litigation

Over her many years of corporate, government, and law firm practice, Ms. Dugan has established a formidable combination of competencies that make her a trusted advisor, skilled problem solver, and widely respected litigator. During her eleven years as General Counsel and Chief Compliance Officer at New Jersey Resources Corporation, she handled a wide variety of litigation, including commercial, securities, employment, regulatory, and mass tort. She also counseled the board of directors and senior management on bet-the-company litigation, commercial transactions, regulatory strategy, risk alignment and compliance, and crisis management. Ms. Dugan understands the needs of corporate clients and knows how to meet those needs in innovative, cost-effective ways.

Prior to joining New Jersey Resources Corporation, Ms. Dugan was an Assistant United States Attorney for the District of New Jersey, where she investigated and prosecuted myriad criminal offenses, including complex fraud schemes, money laundering, political corruption, narcotics, and organized crime. She also tried more than a dozen felony cases to verdict.

Ms. Dugan also served as First Assistant Attorney General and Chief of Staff to the Attorney General of New Jersey. As second-in-command of one of the largest departments of state government, Ms. Dugan was responsible for a broad range of matters, including high-profile litigation and oversight of all twenty-one state county prosecutors and New Jersey State Police. She also counseled state regulators and members of the governor’s cabinet and executive staff on high-level policy matters.

Additionally, Ms. Dugan spent several years at the law firm of Marino, Tortorella & Boyle, P.C., where she practiced complex civil litigation, white-collar criminal defense, and internal investigations, burnishing her reputation as a seasoned litigator.

Since returning to Gibbons in November 2018, Ms. Dugan has represented clients in commercial litigation, white-collar criminal defense, and internal investigations, including the representation of a publicly-traded company in connection with an audit committee investigation of a whistleblower complaint against a high-level executive; a Fortune 50 company in federal and state court ERISA litigations; a Fortune 50 company in a federal criminal investigation; and individuals in federal healthcare, tax, and bank fraud prosecutions.
