Thom Nisbet

Two men in suits are having a serious conversation during a business meeting in an office. One man is facing the camera with a thoughtful expression, and the other has his back to the camera.

Partner | Former Felony Chief Prosecutor | Tactical Criminal Defense Attorney


A serious charge calls for serious experience—and Thom Nisbet brings the kind of courtroom insight that only comes from years on both sides of the law. As a former Felony Court Chief in the Bexar County District Attorney’s Office, Thom has tried thousands of criminal cases and now uses that experience to deliver focused, high-stakes defense for individuals across Texas.

BUILT FOR TRIAL. COMMITTED TO THE FIGHT.


Thom’s reputation is built on preparation, precision, and presence in the courtroom. For more than a decade, he led prosecution teams on some of the most complex and high-profile cases in the region, including intoxication manslaughter, capital murder, white collar fraud, and sexual assault.

Now, as a defense attorney, Thom uses that same tenacity and insight to anticipate every move the government will make—often dismantling their case before trial begins. His transition from prosecutor to defender gives him a unique advantage: he knows what’s coming and how to counter it.

Whether you’re under investigation or already facing charges, Thom is the partner you want when everything is on the line.
