 “Trey McDonald embodies everything one should expect from top-notch legal counsel. His guidance in the midst of contentious litigation and tedious negotiations was not only trusted, but truly counted on, while his poise, command of the documents and facts in the case earned the respect of all parties involved.” — C. Denise Beaudoin, General Counsel, The Dr. Oz Show

William (Trey) McDonald is an experienced litigator and deal maker who focuses his practice on the sports, media, technology, and entertainment industries. He represents corporations, family offices, and high-profile, high-net-worth clients across these sectors. His experience includes media rights, First Amendment media law, Lanham Act claims, false advertising, sports endorsement deals, publishing law, college sports law, and general corporate structuring.

As a seasoned negotiator, Trey successfully brokered some of the first name, image, and likeness (NIL) deals on behalf of high-profile athletes, including Bronny and Bryce James, C.J. Stroud, and several McDonald’s All-Americans. He has also worked with college athletic departments, sports agents, and third-party NIL collectives.

Notably, Trey co-represented Orlando Magic point guard Anthony Black (No. 6 overall pick in the 2023 NBA Draft) in a high-profile lawsuit against the Texas University Interscholastic League, securing an injunction (upheld on appeal) that required state officials to recognize the star basketball player’s eligibility and allow him to participate in varsity athletics during his senior year of high school.

Trey’s keen understanding of industry dynamics, coupled with a strategic approach to negotiations, has consistently delivered favorable outcomes for his clients, including Savannah James, global supermodel Jasmine Tookes, Micah Parsons, NFL super-agent David Mulugheta, Dr. Mehmet Oz, and Sony Pictures Television, Inc.

Prior to joining Foley, Trey practiced at a national law firm in its Houston office. Alongside Foley partner James McFall, he helped lead the launch of sports tech company Lockerverse, one of six companies selected to participate in the prestigious Disney Accelerator.
