Michael Shaheen is a partner in the White Collar & Regulatory Enforcement and Health Care groups in the Washington, D.C. office of Crowell & Moring. His practice focuses on federal litigation, investigations, and enforcement actions. Michael has significant experience with the False Claims Act (FCA), with particular emphasis on health care fraud.

Before joining Crowell & Moring, Michael served as a Trial Attorney with the Fraud Section of the Department of Justice (DOJ), where his work primarily involved investigating and prosecuting FCA matters. At DOJ, he obtained judgments totaling hundreds of millions of dollars and was involved in the settlement of numerous false claims cases of similar magnitude. Michael served in a variety of roles in these cases, ranging from first-chair trial attorney to lead investigator.

More specifically, he successfully tried a high-profile case against individuals charged with violating the FCA and the Anti-Kickback Statute that resulted in a $117 million judgment. Michael also spearheaded DOJ initiatives targeting fraud in the laboratory industry, fraud in skilled nursing facilities and inpatient rehabilitation facilities, and fraud committed by large banks that underwrote Department of Housing and Urban Development backed loans.  

Prior to his government service, Michael was an associate at a leading white collar criminal defense law firm, where he was a member of the defense team that represented a global retailer in one of the largest Foreign Corrupt Practices Act investigations ever conducted.

While at Cornell, Michael participated in the Cornell Death Penalty Project and helped brief a case argued before the U.S. Supreme Court.
