Biography

John focuses his practice on compliance, government enforcement and internal investigations, as well as white collar criminal defense, with an emphasis on the health care and manufacturing industries 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. John also represents medical professionals facing parallel criminal and licensing board matters, as well as defending and counseling health care providers facing False Claims Act investigations, qui tam whistleblower lawsuits, and anti-trust matters. He recently obtained the dismissal with prejudice of all federal False Claims Act and whistleblower retaliation claims against a health care provider client, after successfully defending the accompanying government investigation.

John is a member of the firm's Criminal Defense, White Collar & Government Enforcement Group. John has tried numerous federal and state criminal cases involving bid rigging, fraud, antitrust, political corruption, tax, and national security issues. John’s experience extends to grand jury investigations. John has developed 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.

John has conducted and defended merger and civil non-merger antitrust investigations, represented parties involved in civil antitrust litigation, and represented both acquired and acquiring entities in making HSR filings, primarily in the health care industry. He has also counseled clients in dealing with state antitrust authorities and making required filings when necessary.

Prior to joining the firm, John spent almost 20 years with the United States Department of Justice. John investigated mergers and acquisitions in a variety of industries and prosecuted complex, multi-defendant antitrust and fraud crimes in the health care, financial services, and other industries while working for the Antitrust Division. While working for the Criminal and National Security Divisions, he managed and conducted terrorism and national security investigations and prosecutions. John worked closely with a variety of federal and state law enforcement, investigatory, and regulatory authorities, as well as foreign counterparts, and now uses that experience in representing clients subject to investigation.

After his clerkship, John practiced as a litigation associate at Ropes & Gray before joining the Massachusetts Attorney General’s Office, where he prosecuted political corruption, economic and tax crimes, and other matters before joining the U.S. Department of Justice.

John regularly accepts appointments to provide criminal defense representation to indigent defendants as a Criminal Justice Act (CJA) panel member.
