Brent Mayr brings more than a decade of experience in federal criminal defense and has represented clients not only in Houston and the surrounding communities, but all over the state and the country.

Brent earned his Juris Doctor from South Texas College of Law in 2002. During law school, he clerked for the Houston criminal defense firm of Zimmermann and Lavine, P.C. and assisted with multiple federal cases. Upon graduation, he served as the law clerk for Judge Barbara Hervey of the Texas Court of Criminal Appeals until he became an assistant district attorney for the Harris County District Attorney’s Office. Brent served as the head of that office’s Vehicular Crimes Section before entering private practice.

In 2011, Brent was certified as a criminal law specialist by the Texas Board of Legal Specialization, placing him in an elite group of attorneys who can hold themselves out as specialists in criminal defense. Brent also has the distinguished privilege of being a member of the CJA Panel for the Southern District of Texas. The panel consists of a limited number of federal criminal defense attorneys who are selected by federal judges and other attorneys through a rigorous selection process to represent individuals accused of federal crimes. This “select list” of attorneys is a good source of determining the “Who’s Who” of federal criminal defense practice.

During his career, Brent has been involved in several groundbreaking cases and has earned acquittals for a number of clients. In 2013, he represented an individual charged with Conspiracy to Commit Money Laundering as part of a scheme involving the Zeta drug cartel and the American Quarter Horse Racing industry. His client was the only one out of multiple defendants who was acquitted of all charges at trial. Later that same year, he and famed criminal defense attorney Dick DeGuerin convinced a jury to find their client, a prominent El Paso businessman, “Not Guilty” of Intoxication Manslaughter.

Brent is active the National Association of Criminal Defense Lawyers Association and the Texas Criminal Defense Lawyers Association. He is co-chair of the Ethics Committee for TCDLA and routinely speaks for the organization teaching other lawyers around the state on a variety of topics including cross examination of cooperating witnesses, ethics, and jury selection.
