For more than two decades, Mike Theis has been on the frontlines of litigation involving allegations of fraud and false claims. Nationally recognized for his experience with and understanding of the False Claims Act and qui tam litigation, Mike leads the False Claims Act practice for Hogan Lovells.

Before joining Hogan Lovells, Mike was a pioneer in the health care fraud enforcement efforts undertaken by the Department of Justice following the 1986 amendments to the federal False Claims Act. As a trial lawyer in the Civil Division from 1988 to 1997, he was responsible for the recovery of millions of dollars under the False Claims Act and established some of the key precedents interpreting the qui tam provisions of the Act.

Today, Mike is a partner in the Investigations, White Collar and Fraud practice of Hogan Lovells. He is highly skilled in counseling individuals and companies who face government scrutiny for fraud and false claims. He draws on his comprehensive experience in both government and private practice, civil and criminal investigations, and trial work to provide clear, creative, and collaborative advice to companies targeted in federal law enforcement investigations. He is routinely called upon to negotiate "global" settlements of complex criminal, civil, and administrative enforcement matters.

As an Assistant U.S. Attorney in the District of Colorado from 1997 to 2005, Mike handled dozens of False Claims Act cases. He also investigated and prosecuted health care fraud, mail fraud, and wire fraud offenses, trying several cases to verdict in federal court.
