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.


Assault and Battery

Whether you have been charged with Assault or Assault Family Violence it is critical that you retain counsel immediately. The State is not going to dismiss the case just because the other party does not want to move forward.


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.
