Bryston C. Gallegos

Bryston Gallegos is a trusted advocate for high-stakes disputes at all stages of litigation, with an emphasis on trying complex commercial cases.

Bryston is a fast-rising trial lawyer.  He has won multiple trials and handled matters of national significance covered by the Wall Street Journal, New York Times, and Financial Times, among others.  In 2025, Bryston and Gibson Dunn’s Texas litigation teams secured record-setting jury verdicts exceeding $1 billion for their clients and twice earned national recognition as AmLaw’s “Litigators of the Week.”

Bryston also has considerable experience representing clients before and after trial, shaping cases from the earliest pretrial phase to the court of last resort.  He has litigated appeals and critical motions in federal and state courts across the country, including the U.S. Supreme Court, and across a wide range of subject-matter areas.

Representative Matters:

• Trial counsel for Energy Transfer LP and Dakota Access LLC in a landmark trespass and defamation action against Greenpeace that culminated in a $667 million jury verdict—the largest in North Dakota history.  The American Lawyer recognized the trial team with its “Litigator of the Week” honors (March 2025).
• Trial counsel for Arizona real estate development companies Gray Development and Gray Services in a 12-day trial that resulted in a sweeping victory and a $296 million jury verdict—the full amount of damages sought.  The American Lawyer recognized the trial team with its “Litigator of the Week” honors (October 2025).
• Trial counsel for wind farm operator Enel Green Power in a suit brought in Oklahoma federal court by the U.S. government and the Osage Nation.  Hired on the eve of a damages trial after an adverse liability ruling in a case chronicled by the Wall Street Journal, Bryston and the trial team convinced the court to strike the plaintiffs’ main expert as unreliable and award less than 1% of the damages sought.
• Persuaded U.S. District Court for the Northern District of Texas to grant summary judgment to GE Vernova International on more than $400 million in claimed damages in a fraud case involving failed plans to construct power plants using adapted jet engines.
• Convinced Fourteenth Texas Court of Appeals to unanimously reverse dismissal of 18 consolidated cases in multidistrict litigation concerning health-insurance dispute over the calculation of hundreds of millions of dollars in reimbursements for distributing prescription drugs.
• Represented LIV Golf and professional golfers in major antitrust litigation against the PGA Tour.
• Defended GameStop in a suit in the federal district court of Delaware brought by Boston Consulting Group over the validity of hundreds of millions of dollars of consulting services contracts.

Bryston is deeply committed to serving the legal profession and is active outside the courtroom.  He maintains a robust pro bono practice, with a focus on religious liberty issues and crime victims’ rights.  He also serves as an adjunct professor at SMU Dedman School of Law, where he co-teaches an innovative course on evidence advocacy centered on using clear, persuasive courtroom arguments that make judges take notice.

Before joining the firm, Bryston served as a law clerk to the Honorable Bobby R. Baldock of the U.S. Court of Appeals for the Tenth Circuit and to the Honorable Sean D. Jordan of the U.S. District Court for the Eastern District of Texas.

Bryston earned his law degree in 2019 from the University of Denver Sturm College of Law, where he received the Kenneth L. Smith Award for having the highest GPA in the class through five semesters and the Melanie Hardaway Memorial Award for making the greatest overall contribution to the law school during his academic tenure.  He served as an Articles Editor of the Denver Law Review and was elected to the Order of the Coif.  Bryston also graduated magna cum laude from Oklahoma Christian University with a Bachelor of Arts in History.
