Dave is a nationally-recognized former Department of Justice prosecutor and high-profile trial lawyer, with more than 16 years of experience in high-stakes legal proceedings. He represents organizations and individuals in a wide variety of investigations, hearings, administrative actions, trials, and enforcement proceedings brought by federal and state government agencies, primarily in the health care and life sciences industries. Dave also represents clients in civil litigation and business disputes.

Prior to joining Verrill, Dave spent more than 16 years as a prosecutor, including nearly a decade with the Department of Justice in both Massachusetts and Florida as an Assistant United States Attorney in the Criminal and Civil Divisions. In Boston, Dave held a senior leadership role and investigated and prosecuted some of the largest and most-complex health care and white-collar cases in the country, including those relating to pharmaceuticals and opioids, pharmacies, charitable co-pay foundations, hospitals, physician practices (small and large), government and commercial insurers, payment and reimbursement, durable medical equipment manufacture and supply, and telemedicine. Among his many significant trials, Dave was one of the lead trial lawyers on the 53-day racketeering trial of the billionaire founder of opioid manufacturer Insys Therapeutics, Inc.

Dave also delivers deep experience and knowledge in criminal and civil asset forfeiture, restitution, money laundering, and high-stakes financial penalties, including the pre-trial restraint and seizure of assets, such as complex assets and cryptocurrency. Dave also has experience in cybersecurity and privacy, including prosecution of business email compromise matters, and received specialized training from the Department’s Computer Crimes and Intellectual Property Section.

A dynamic public speaker, Dave is regularly sought out to teach and speak on matters related to health care regulation and enforcement, and government investigations and has taught more than 2,000 federal and state health care enforcement agents and prosecutors how to conduct parallel investigations and health care fraud enforcement. Dave has also appeared on television shows including 60 Minutes on CBS, Alex Gibney’s Crime of the Century on HBO, and American Greed on CNBC.

Dave began his legal career prosecuting violent crime and homicide cases in New York City.

Outside of the office, Dave enjoys skiing and running, coaching youth soccer, and spending time with his wife, three boys, and high-energy Vizsla.
