Top DUI Lawyer in Austin

I had an outstanding experience with attorney Trey Porter. I retained his services for a DUI charge. The police violated my rights, and their carelessness put me in jeopardy of losing my job and career. Porter fought for me. Really fought for me. He got my DUI charge dismissed in Travis County co...urt, and I have since completed the expunction process to delete this whole thing. I recommend Mr. Porter and his law firm 100/100.

Best DWI Lawyer in Texas!

Mr. Trey Porter got my DWI case dismissed and then expunged. Whole record is wiped clean and I am so grateful for Mr. Porter’s work. I really can’t say enough good things. Recommend him 100/100.

Best DWI Lawyer in TX!

BEST DWI Lawyer! Hired Porter for DWI first. Couldn’t take a conviction because of work and prosecution wouldn’t budge on wanting me to get convicted and lose my job. Mr. Porter got my DWI dismissed by challenging the breath evidence they had on me. Found a technicality and it worked! My case... was dismissed and I will soon have this deleted entirely. I recommend Mr. Porter and the whole the firm to anybody and everybody facing a DWI that needs a WIN!

Excellent Lawyer!

I strongly recommend Trey Porter! I think he is the best DWI lawyer out there. Mr. Porter was recommended to me by a friend and I’m so glad I called. Two minutes in, I knew this was the law firm for me! My DWI charge was dismissed, and I will be able to delete my record in a few months time. ...Call Trey Porter!

10 Stars — Excellent!

I really recommend Trey Porter as a lawyer and counselor. I received a bogus charge in Fredericksburg visiting on a girls trip. I was shocked with how police treated me. I found Trey Porter online and did a consultation over zoom the same day! He put me at ease. He did what he said he would do. My ch...arge was dismissed and we just finished the expnging process. I never had to appear in court and received constant updates from the friendly office staff. 10/10!!!

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
