Biography

Sean Gallagher is a business trial lawyer who represents plaintiffs and defendants in high-stakes disputes before judges and juries. Since 2020, Sean has been named to the Super Lawyers’ Texas Rising Stars list, which recognizes the state’s top young lawyers and is awarded to only 2.5 percent of eligible attorneys each year. Recently, Sean was also named to Best Lawyers’ 2022 list of “Ones to Watch”—a recognition awarded to attorneys early in their careers for outstanding professional excellence in private practice.

Throughout his career, Sean has represented parties ranging from private citizens to Fortune 500 companies across a broad array of complex issues, including fraud, breach of contract, breach of fiduciary duty, director and officer liability, business divorces, partnership disputes, trademark and copyright disputes, Lanham Act claims, RICO claims, civil rights claims, and False Claims Act litigation. Sean has also argued and briefed multiple issues of first impression that have helped shape the law on some of these issues.

Before joining Jackson Walker, Sean practiced at two nationally-recognized litigation firms, honing his skills as a trial lawyer and obtaining a number of favorable outcomes for his clients, including multiple judgments on behalf of both plaintiffs and defendants.
