John M. Fietkiewicz

Senior Counsel

John Fietkiewicz draws on three decades of experience as a federal prosecutor in the District of New Jersey to counsel a wide array of corporate and individual clients in dealing with criminal and civil investigations and litigation. He defends clients in criminal prosecutions and government investigations, conducts internal investigations, counsels on corporate compliance, and litigates complex civil claims. During his career in government and private practice, John has personally handled and supervised a variety of white collar matters from the investigative stage through trial and appeal. These cases have involved bank, corporate, health care, securities, and tax fraud; official corruption; antitrust; money laundering; defense contracting; and cybercrime.

As part of the U.S. Attorney's executive team from 2010 until 2018, John oversaw the full array of criminal and civil cases handled by the approximately 150 attorneys in the Office. Notably, as Counsel to the U.S. Attorney, he created, implemented, and managed an innovative office-wide criminal trial program through which he supervised all criminal trials and provided advice to all trial teams on legal and evidentiary issues, trial strategy and tactics, witness preparation, witness examinations, and jury arguments. In his many years as a supervisor and Senior Litigation Counsel, John trained AUSAs on federal law and practice and in their handling of investigations and prosecutions.

Earlier in his career, John was the Editor-in-Chief of the Fordham Law Review, a Law Clerk to the Honorable Gerard L. Goettel, U.S. District Judge, Southern District of New York, and a civil litigator at a large New York law firm.

John is a frequent lecturer and panelist on numerous topics concerning white collar prosecutions, trial practice, evidence, professional responsibility, and federal criminal practice.
