San Antonio DWI Lawyer

You can’t win if you don’t fight. If you have been arrested and charged with DWI in San Antonio, you are facing serious, life-long consequences. Hiring the best San Antonio DWI defense lawyer will be one of the most important decisions you make. 

Experience matters. I have represented hundreds of individuals facing a wide array of criminal charges, from trespassing to murder. Every case is different, but my goal is always the same: get the charge dismissed.


100% Dedicated DWI Attorney

My practice is 100% dedicated to Criminal Defense, with a focus on DWI, DWI .15+, DWI 2nd, DWI 3rd, DWI Open Container, and Public Intoxication. I also represent individuals that have been previously charged with DWI, that are seeking an expunction or non-disclosure.


Only 15 Days to Save License

Time is of the essence. If you’ve been charged with a crime, the State is already working on your conviction. You may already find yourself losing the liberty to travel, or operate a motor vehicle. Specifically, with DWI you only have 15 days to act to protect your driver’s license. Failing to act may result in a driver’s license suspension, which could in turn set you up to be arrested again for Driving While License Invalid.


Fight for DWI Dismissal

A DWI conviction will stay on your record forever. Don’t jeopardize your future by trying to go it alone or with a court-appointed attorney that’s getting paid the same no matter what happens to you. If you’re facing a criminal charge, reach out today for a free consultation and we can talk about a game plan for success.

I hired Mr. Trey Porter after getting a D.U.I. Was very much scared because I am a nurse and thought I would lose my livelihood. Mr Porter was reassuring and kind. He was also very confident.

Stephen, October 2017

Mr Porter was recommended to me by a coworker. He helped her out of a DWI 3 years ago, and he did the same for me.

Sammy, September 2017

Mr. Porter is very professional, he works diligently, efficiently, is in constant contact, and prompt!!! The key ingredients for a great lawyer.

Sheila Torres, July 2018

Trey is one of the best in the business. I was in complete shock of the outcome for the case, the best scenario was achieved in a not so great situation. Would absolutely recommend to everyone.

Stacey Reyes, November 2018

Trey is a phenomenal attorney that gets the job done right! He is dedicated to helping his clients. He made himself available and answered all my concerns immediately!

DWI, DWI .15+, DWI 2nd, and DWI 3rd or more all come with serious consequences. If you have been charged with any type of driving while intoxicated offense, you only have 15 days to contest your driver’s license suspension.


Public Intoxication

Public Intoxication is a frustrating charge. Law enforcement doesn’t even have to prove intoxication.
While you cannot be sentenced to jail for a Public Intox. charge, it’s important to make sure it doesn’t go down as a conviction on your permanent record.


Probation Violations

A failed drug test, or a high blow on an ignition interlock device can result in a Motion to Revoke (MTR) your probation. This results in a warrant for your arrest, and can jeopardize your probation and freedom.


Record Sealing

Have an old DWI conviction or other criminal charge on your record? You may be eligible to seal or expunge it. Don’t let a mistake from years ago hold you back. Contact me today to find out if you qualify and start living your life again.
