Damon is a trusted lawyer and advisor to multinational clients navigating high-stakes white collar investigations and government enforcement matters. He supports clients through every phase of the enforcement lifecycle—from pre-litigation internal investigations and regulatory inquiries through complex trial litigation and appeals in state and federal courts.

Damon's practice covers a wide swathe of federal enforcement work, with deep experience representing clients in a variety of matters before the U.S. Department of Justice, Federal Trade Commission, and Securities and Exchange Commission. His matters span investigations involving the Foreign Corrupt Practices Act, False Claims Act, federal securities laws, and federal antitrust laws, as well as litigation that may accompany government inquiries. Damon also counsels clients on designing and implementing corporate compliance programs to withstand regulatory scrutiny.

Damon is practical and client-focused: he combines rigorous legal analysis with learning and prioritizing his clients' business objectives to efficiently resolve sensitive matters with minimal disruption. His real-world experience representing clients in the aerospace, defense, information technology, and pharmaceutical industries lets him quickly familiarize himself with a client’s business and internal culture, become steeped in the details of a matter, and bring relevant facts to bear in crafting solutions.

Prior to joining Cadwalader, Damon was an associate in the litigation and trial practice of another global law firm, focusing on antitrust and competition matters alongside white collar defense. While earning his J.D. at Georgetown, Damon served as a Vetting Associate in the Obama administration's Office of Presidential Personnel and later as a judicial intern for Judge Ketanji Brown Jackson of the U.S. District Court for the District of Columbia. Damon also maintains an active pro bono practice.
