Mayr Law: A 2021 “Lawyer of the Year” Whose DWI Cases Have Reached National Television

Brent Mayr was named 2021 Lawyer of the Year by the Harris County Criminal Lawyers Association and has secured not-guilty verdicts in cases spanning fatal DWI incidents to federal money laundering — including a case featured in Apple TV’s “Cowboy Cartel” series — giving him a documented complex-litigation track record well beyond typical DWI defense.

At a Glance

Origin and Background

Brent Mayr is Board Certified in Criminal Law by the Texas Board of Legal Specialization, a credential the firm notes fewer than 7.5% of Texas’s 100,000-plus attorneys hold. His practice spans complex state and federal criminal litigation, with case coverage from the Washington Post, 60 Minutes, the Houston Chronicle, ABC, CNN, the New York Times, and NBC. He is licensed to practice before the U.S. Supreme Court, four federal district courts in Texas, and the Fifth Circuit Court of Appeals.

Practice Concentration

DWI/DUI defense is a distinct, dedicated practice area for the firm, alongside intoxication manslaughter, vehicular assault, homicide, federal crime, and white-collar defense. See this Houston DWI/DWI Defense directory for how this complex-litigation-focused practice compares to other Harris County defense firms. Mayr’s documented DWI-adjacent work includes securing an acquittal for a police officer involved in a fatal accident and convincing a jury to recommend probation rather than prison time in a fatal DWI case.

Track Record

The firm’s published notable victories include a not-guilty verdict for a Houston police officer involved in a fatal accident, a not-guilty verdict (with co-counsel Dick DeGuerin) for a client charged with intoxication manslaughter, an acquittal on two counts of criminally negligent homicide, a grand jury declination to indict a murder suspect, and a probation recommendation in a fatal DWI case that could have carried significant prison time. These are firm-published, self-reported results and have not been independently re-verified against court dockets by this profile; past results do not guarantee similar outcomes, and every case depends on its own specific facts.

Client Voice

A client testimonial specific to a DWI case describes Mayr as attentive and realistic about both favorable and unfavorable case scenarios, with the case ultimately dismissed. Awesome Attorneys did not identify a pattern of negative or unresolved reviews warranting disclosure.

Beyond the Courtroom

Mayr’s national media coverage, including a case featured in a documentary series, and his multiple President’s Awards from the Texas Criminal Defense Lawyers Association reflect standing within the broader criminal defense field beyond individual case outcomes.

Recognition

Mayr’s Board Certification in Criminal Law from the Texas Board of Legal Specialization is the state’s official specialty credential. His 2021 Lawyer of the Year award from the Harris County Criminal Lawyers Association and his continuous Texas Super Lawyers selection since 2014 (plus Houston Top 100 in 2025) are peer-nomination-based distinctions, distinct in character from general media coverage of his cases.

Texas Legal Backdrop

A Texas DWI arrest triggers two separate proceedings: the criminal case, and a civil Administrative License Revocation (ALR) case against the driver’s license, with only 15 days from arrest to request the ALR hearing before an automatic suspension takes effect. Intoxication manslaughter is a second-degree felony under Texas Penal Code §49.08, carrying 2 to 20 years in prison. None of this is legal advice; anyone facing a DWI or intoxication-related charge should consult a licensed Texas attorney about the specific facts of their case.

Awesome Attorneys Assessment

Mayr Law’s clearest, most checkable differentiator is Brent Mayr’s documented track record on the most serious end of the DWI spectrum — fatal-accident and intoxication manslaughter cases — paired with TBLS Criminal Law certification and national-media-covered federal case experience. The honest trade-off: DWI/DUI is one practice area among several complex-felony categories at this firm rather than the firm’s sole focus, and the published case results are self-reported rather than independently re-verified by this profile. For a Harris County client facing a serious or high-stakes DWI charge specifically — particularly one involving injury or death — this level of complex-litigation experience is a genuine, checkable basis for a shortlist.
