Additionally, Mark supports clients in managing FCPA matters related to the DOJ and U.S. Securities and Exchange Commission (SEC), as well as investigations relating to cybersecurity issues. He has worked closely with government authorities to minimize exposure and advised on ESG litigation and compliance procedures.

He has deep experience on matters relating to the False Claims Act, healthcare fraud, the opioid crisis, and competition and consumer harm in the online marketplace.

Mark also has extensive experience on Capitol Hill, having served as a member of Sen. John Ashcroft’s staff, and later on a special House investigations committee led by Chairman Trey Gowdy and ranking member Elijah Cummings.
