Thornton Criminal Defense: The Former Chief Prosecutor Now Defending DWI Cases in the Same County

TO OUR READERS: This profile is independent editorial content produced by Awesome Attorneys. Thornton Criminal Defense, PLLC did not pay for, commission, sponsor, or review this article, and inclusion in this series cannot be purchased. Nothing here is legal advice, an endorsement, or a recommendation to hire any lawyer; readers should evaluate counsel independently and may verify any Texas attorney’s license and discipline history through the State Bar of Texas at texasbar.com. Facts are drawn from the sources identified in the Methodology section and were verified as of August 2026.

AT A GLANCE

I. From Chief Prosecutor to Defense Attorney

Brad Thornton spent part of his career as Chief Prosecutor for the 81st Judicial District Attorney’s Office, where he oversaw all cases in Atascosa County and led the team assigned the most serious DWI matters. He has since built a defense practice in San Antonio and South Texas, and his marketing leans directly into that prosecutorial background: an inside-out understanding of how the state builds its cases, used to anticipate tactics and challenge evidence in Bexar County courts. He is Board Certified in Criminal Law by the Texas Board of Legal Specialization, a credential the firm describes as held by less than 0.008% of Texas attorneys (a figure the firm attributes to its own marketing materials rather than an independently sourced statistic, and is reported here as the firm’s claim).

II. DWI as a Specific, Named Focus Within Criminal Defense

While the firm handles the full range of criminal charges, from misdemeanor theft to murder, DWI and vehicular crimes get dedicated attention: the firm’s site describes a “specialized” focus on driving-while-intoxicated cases, including intoxication assault and intoxication manslaughter, distinct from the general criminal defense caseload.

III. Practice Areas

• DWI/DUI defense (including felony and repeat-offense cases)
• Criminal defense: felonies and misdemeanors
• Assault and family violence assault
• Evading arrest
• Drug crimes, including marijuana and THC vape pen charges

IV. Case Outcomes

The firm publishes specific, if anonymized, case summaries rather than dollar-figure results, consistent with the nature of criminal defense work. Examples from the firm’s own site include a client charged with assaulting a coworker whose case was dismissed after the client proactively completed anger management classes before the first court date, and a client involved in a head-on collision with an 18-wheeler where open containers were found in the vehicle; the firm reports securing a dismissal after challenging law enforcement’s testing procedures and identifying errors in the investigation.

PAST-RESULTS DISCLAIMER: Every case is different, and these outcomes, as published by the firm, do not guarantee or predict the outcome of any future case.

V. The Client Voice

Avvo shows a perfect 5.0 rating across seven client reviews. One client described Thornton as “an incredibly Outstanding and Powerful Criminal Defense Attorney” who “takes the time to speak with his Clients and learn every detail about their case.” Another review specifically praised his “commitment to his clients and his individualized approach,” crediting it with making “a significant difference” in the outcome. No pattern of negative or unresolved reviews was located for this firm as of this research date.

VI. Community and Local Presence

The firm maintains a primary San Antonio office and a secondary office in Pleasanton, in Atascosa County, reflecting Thornton’s earlier prosecutorial tenure in that same county. No broader civic or pro bono program is documented on the firm’s public materials as of this research date.

VII. Credentials and Recognition

Brad Thornton is Board Certified in Criminal Law by the Texas Board of Legal Specialization, a genuine peer- and exam-based credential distinct from marketing-program awards. No other third-party peer-review credentials (Super Lawyers, Best Lawyers, Martindale-Hubbell) were located on the firm’s public materials as of this research date.

VIII. The Texas Legal Backdrop

In Texas, a first-offense DWI is generally a Class B misdemeanor, but penalties escalate with aggravating factors: a DWI with a passenger under 15 is charged as a state jail felony under Texas Penal Code § 49.045, regardless of whether it is a first offense, and repeat or high blood-alcohol-content DWIs carry their own enhanced penalty structures under Texas Penal Code Chapter 49. Texas driver’s license suspension for DWI-related offenses is governed separately under the Texas Transportation Code. None of this is legal advice; consult a licensed Texas attorney about your specific situation.

IX. The Awesome Attorneys Assessment

Thornton Criminal Defense’s structural strength is a genuinely disclosed prosecutorial background, specifically as a former Chief Prosecutor overseeing serious cases including DWI in the same county where the firm now maintains a satellite office, paired with formal board certification in criminal law. For a Bexar County or Atascosa County client facing a DWI or other serious criminal charge, that combination of inside knowledge and credentialing is a genuine, checkable asset.

The honest limitation is one common to prosecutor-to-defense career paths generally: a client should ask directly how the firm’s caseload is staffed day to day, since a single named attorney with a strong reputation cannot personally handle unlimited simultaneous matters at the same level of individualized attention the marketing describes.
