Mr. Regan represents and counsels clients in their most vexing matters, often involving regulatory and public relations components or novel jurisdictional, substantive and procedural issues.

Shawn has extensive experience in the financial services, energy, consumer/retail and data/technology industries. He handles cross-border litigation, government and regulatory investigations, complex business disputes, securities litigation and putative class and mass actions, involving contracts, torts, fraud and other common law and statutory claims including some intellectual property matters.

In addition to his work as lead trial counsel in arbitral forums and state and federal courts, Shawn has argued and been lead counsel of record in numerous successful appeals, including in several United States Circuit Courts of Appeals, the New York State Court of Appeals and the Supreme Court of the United States.

He enjoys collaborating with clients and other outside counsel on complex issues to utilize strategically each team member's unique skills, attributes and experience to bring about the most effective and efficient result for clients.

Shawn began his career as a law clerk to Judge Kevin Thomas Duffy in the U.S. District Court for the Southern District of New York, a court in which he remains heavily involved in practice and service.

He also maintains a diverse pro bono practice that has included achieving political asylum for several Tibetan refugees, successfully prosecuting a number of actions under the Hague Convention on International Child Abduction and, at the request of an SDNY judge, representing an elderly woman swindled from her home in a 20-year fraud, ultimately achieving unencumbered return of the property by settlement.
