John Van Lonkhuyzen is a partner in the firm’s Trial Group and chairs its Criminal Defense, White Collar and Government Enforcement Practice Group. John focuses his practice on compliance, government and internal investigations, and white collar criminal defense, with an emphasis on the health care industry and antitrust matters. John has extensive experience leading complex multi-defendant investigations, managing vast amounts of electronic data and confidential information, building cases, and trying those cases to verdict – or resolving them short of charge or trial where that is appropriate.

Mr. Van Lonkhuyzen has tried numerous federal and state criminal cases involving bid rigging, fraud, political corruption, tax and national security issues. He has also conducted and defended merger and civil non-merger antitrust investigations. John has investigated and tried cases in federal district courts across the United States, and in various counties in the Commonwealth of Massachusetts. He has also argued appeals before several United States Courts of Appeals.

Prior to joining the firm, John spent almost 20 years with the United States Department of Justice, where he worked in the Antitrust, Criminal and National Security Divisions. John investigated mergers and acquisitions in a variety of industries, and prosecuted complex, multi-defendant bid-rigging and other white collar crime in the health care, financial services and other industries for the Antitrust Division. He also managed and conducted terrorism and national security investigations and prosecutions for the Criminal and National Security Divisions. As a prosecutor, John has worked closely with a variety of federal and state law enforcement, investigatory and regulatory authorities, as well as foreign counterparts.

After his clerkship, John practiced as an associate in the Litigation Department of Ropes & Gray from 1985 until 1991, where he represented health care, higher education and high-tech clients in antitrust, medical malpractice, intellectual property and other matters. John then joined the Office of the Massachusetts Attorney General, where he prosecuted political corruption, economic crimes and other matters, before joining the U.S. Department of Justice.

John has served as a bar advocate, providing criminal defense representation to indigent defendants, and on the boards of directors of several day care centers. Prior to starting his family, he was a frequent trip leader for the Appalachian Mountain Club. Now that his children are older and he has returned to his roots in New England, he looks forward to spending more time with them in the mountains and on the water.
