Sean Gallagher has spent more than 25 years representing clients in boardrooms and courtrooms across the country and is one of only a handful of Colorado lawyers in the history of the state to have argued a case in the Supreme Court of the United States and prevailed with a unanimous decision.

Noted by the Chambers USA guide for his "excellent follow through," Sean's practice emphasizes three general areas: complex commercial litigation, employment counseling/litigation, and constitutional/public policy matters.

His representative commercial litigation experience includes cases involving claims for common law fraud and misrepresentation, securities fraud, defamation, antitrust violations, consumer protection violations, theft of intellectual property, whistleblowing and violations of the False Claims Act, and corporate governance disputes. Sean also assists clients in implementing proactive employment policies that minimize the risk of litigation. When necessary, however, he represents senior executives and management in all aspects of employment litigation.

Sean has also handled a broad spectrum of public policy, constitutional, and election matters, including several First Amendment cases of national significance. He has served as national counsel for three presidential campaigns, has twice been appointed a Special Assistant Attorney General by the State of Colorado, and has been retained on multiple occasions by the U.S. Department of Justice to represent federal officials in civil litigation. In 2012, he successfully represented two U.S. Secret Service agents in the Supreme Court of the United States in Reichle v. Howards, 566 U.S._(2012) where he obtained a unanimous decision on behalf of his clients in a case involving the scope of civil liability of Secret Service agents protecting the President and Vice President.

As an adjunct to his litigation practice, Sean is nationally recognized for his experience in the field of electronic discovery. He is a member of The Sedona Conference's Working Group on Best Practices for Electronic Document Retention and Production and helped lead a team that drafted the conference's commentary on Proportionality in the e-Discovery Process. He has lectured extensively on litigation, ethics, and electronic discovery matters.
