Sydney Scott

Sydney Scott is a partner in Gibson Dunn’s Houston office and a lead trial lawyer clients turn to when significant commercial disputes are headed to trial. She is regularly called on to take command of complex, high-stakes disputes—including matters in which she has been retained just weeks before trial—quickly identify the issues that will matter to the judge or jury, and lead teams through trial. Her recent results include a $296 million jury verdict, complete injunctive relief following a federal bench trial, and a complete victory in a multimillion-dollar arbitration. She also has a strong appellate record, with significant victories in state and federal courts.

Sydney received her law degree from the University of Pennsylvania Law School, where she served as an Articles Editor for the University of Pennsylvania Journal of Constitutional Law. She graduated from Dartmouth College with a Bachelor of Arts degree in English.

Sydney clerked for the Honorable Carl E. Stewart, then Chief Judge of the United States Court of Appeals for the Fifth Circuit, and the Honorable James J. Brady of the United States District Court for the Middle District of Louisiana.

Before law school, Sydney played Division I basketball at Dartmouth, winning three Ivy League championships. She later played professionally in Copenhagen, where her team won the Danish Women’s League championship. That competitive background continues to shape her approach to trial practice, preparation, and team leadership.

Sydney is admitted to practice in Texas and before the United States Courts of Appeals for the Fifth and Sixth Circuits and the United States District Court for the Southern District of Texas.
