Professional Biography

Trey Martinez is the Partner with MBMT Law Firm, based in Brownsville, Texas, where he concentrates his practice on criminal defense law.

Widely regarded as a skilled and formidable trial attorney, Trey is known for his strategic judgment, courtroom presence, and unwavering commitment to protecting the rights of individuals facing serious criminal charges. Drawing on extensive experience at the federal and trial levels, he has built a strong reputation for delivering disciplined, results-driven advocacy and is respected by peers and clients alike for his integrity, preparation, and dedication to the practice of criminal defense.

Trey was born and raised in Brownsville, Texas. After completing high school at St. Joseph’s Academy in Brownsville, Texas, he had the good fortune of attending Brown University in Providence, Rhode Island. He received two majors, one in political science and one in psychology. He came back to Texas to go to law school at the University of Texas in Austin. While in law school, he was elected as class president.

After graduation, he went on to be a law clerk to Judge Reynaldo G. Garza on the Fifth Circuit Court of Appeals. Upon completing his clerkship, he became an Assistant United States Attorney. At the age of 25, besides being one of the youngest prosecutors the United States Government had ever hired, he successfully tried a number of cases to juries. He left the U.S. Attorney’s Office in 2000 and has since been a lawyer in private practice doing what he loves best; argue cases to juries, although now he concentrates on civil cases.

He has been very successful in his practice and has now dedicated a lot of time to improving both the practice of law as well as defending the rights of those who cannot defend themselves. He serves on several statewide legal boards and is actively involved in the community.
