Erin Sullivan has years of experience representing corporate and individual clients involved in investigations, prosecutions, and civil enforcement actions by federal and state government entities. She routinely conducts internal investigations, whether prompted by an existing government investigation or initiated internally for business or compliance reasons. Erin also counsels clients on an array of compliance issues, ranging from general compliance best practices to specific compliance with federal laws such as the Foreign Corrupt Practices Act and U.S. sanctions and export control regimes.

Erin has represented clients in matters involving alleged criminal violations of the Title 18 fraud statues, FCPA, government procurement laws, tax laws, export control laws, healthcare laws, environmental laws, and securities laws, among others. She also represents clients facing civil investigation or enforcement action by regulators such as the Securities and Exchange Commission and the Federal Trade Commission. She has particularly extensive experience representing healthcare providers and government contractors defending allegations under the civil False Claims Act.

Erin has represented clients at trial, both criminal and civil. When proceeding to trial has not been the preferred course of action, she has negotiated settled resolutions, most often resulting in payments or penalties far below those originally sought by the enforcement agency in question. 

Erin clerked for Judge L. Scott Coogler and Judge Robert Propst in the Northern District of Alabama. Prior to her clerkship, she was an associate in the Washington, D.C., office of an international law firm, where her practice focused on the Foreign Corrupt Practices Act.

Erin also participates in the D.C. Superior Court Pro Bono Program, which provides pro bono representation to clients facing criminal charges in D.C. Superior Court.
