What You Are Afraid Of

A criminal accusation brings dread into your life and into the lives of the people who love you. You worry about your freedom, your family, your job, your name, and how you will pay for any of it, all at once. That is normal. It is also the moment when people make their worst decisions. They talk to the detective. They wait to see what happens. What you need now is a trial lawyer who has been through this many times and will tell you the truth about where you stand. The more serious the accusation, the more carefully you should choose. Your name is on the line. So is mine, every time I walk into a courtroom.

Why clients hire me

People do not hire me for a flashy website. They hire me because the stakes are high and they want judgment, credibility, and real courtroom experience. As a former chief prosecutor and longtime defense lawyer, I know how criminal cases are built, where they are weak, and how to press on the weak points. I bring disciplined preparation, blunt advice, and trial-readiness to every case. When you are facing the power of the State, experience alone is not enough. You need experience that matters.

Case Result

  • In a Capital Murder Charge, we were able through excellent prep and investigation to show that the State would not be able to corroborate  any of the allegations made by coconspirators against my client - By aggressively challenging the timeline and forensics, the State was forced to reevaluate the strength of its case - case dismissed.
  • In an Aggravated Sexual Assault Case the allegations depended heavily on the credibility and reliability of the state’s Complainant.  Aggressive use of Discovery, Specific Brady Requests, Forensic Digital Tools and massive record collections, we were able to show the state the weakness of their case - case dismissed .
  • In a Murder Prosecution, through the use of experts, massive investigation, and a much better understanding of the laws of self defense, resulted in a 15 minute acquittal.

More Than Thirty-Nine Years in Criminal Courtrooms

I am a native Texan, born in Goliad and raised in San Antonio. I began my career as an Assistant District Attorney in Bexar County straight out of law school and was soon trying murder and sexual assault cases. For the next thirty years I maintained a law practice defending people accused of crimes. I returned to the District Attorney’s Office from 2019 to 2022 as Chief of the Criminal Trial and Major Crimes Divisions. Today I defend people charged with serious felonies, including a former SAPD officer in the Melissa Perez trial.
