Jay is a former federal prosecutor who represents corporations and individuals in white-collar criminal and civil matters, internal investigations, and compliance counseling.

Jay most recently served as the Acting U.S. Attorney for the District of New Hampshire. He brings over 15 years of distinguished experience as both a federal and state prosecutor to Verrill. His practice focuses on the defense of a broad spectrum of investigations and criminal, civil and administrative enforcement proceedings. With significant experience in the health care sector, Jay defends matters involving the False Claims Act, Anti-Kickback Statute, billing privacy, Illegal prescribing and civil Controlled Substances Act violations. More broadly, he defends clients against various allegations of fraud, money laundering, export and trade controls, including customs fraud enforcement and COVID-19 grant fraud (e.g., PPP and EIDL).

Jay has held numerous leadership and prosecutorial roles in two states and the U.S. Department of Justice, with a strong focus on health care fraud and financial crimes. Prior to serving as the Acting U.S. Attorney in New Hampshire, he was the First Assistant U.S. Attorney for the District of New Hampshire, where he oversaw all criminal and civil matters and played a key role in establishing the Department of Justice’s New England Health Care Fraud Strike Force. He worked in tandem with the Strike Force and led complex prosecutions involving health care fraud and white-collar crime.

Earlier in his career, Jay was a Trial Attorney in the DOJ’s Fraud Section Health Care Fraud Unit in Washington, D.C., prosecuting sophisticated health care fraud cases nationwide, including as a member of the Department of Justice’s Health Care Fraud Strike Force in Detroit, Michigan. He served as an Assistant Attorney General in the Massachusetts Attorney General’s Office Medicaid Fraud Control Unit, where he investigated and prosecuted health care fraud, anti-kickback violations, and money laundering offenses. Before joining the Massachusetts AG’s Office, Jay worked as a senior prosecutor in the New Hampshire Attorney General’s Office, leading homicide and public integrity investigations from across the Granite State and trying those cases to verdict in court.

Outside of work, he enjoys spending time with his family on the ski slopes of New England and the beaches of Cape Cod.
