    Trey is the man! I hired him because I had overheard a county court judge mentioning how awesome of an attorney he is, so if an endorsement from a judge won’t convince you then I’m not sure what will. I sure do hope I never find myself in a pickle ever again but if I do, I would hire Trey in a heartbeat. He’s honest, transparent, doesn’t beat around the bush, and will work tirelessly so that your clean record stays clean and unblemished. 5 stars, highly recommend!


    I recently hired Trey Porter Law to help our teenage daughter with a drug charge. In the state of Texas she was being charged as an adult which carried a much stiffer penalty. Trey is very responsive, helpful, knowledgeable and is always available to answer any questions or concerns via phone, text or email. He was able to negotiate on her behalf so it was a pleasant experience. I would highly recommend Trey Porter Law.


    Trey really helped me out. He was straight forward and professional, and really helped me in my case. I thought i was going to lose my job, but trey did everything in his power to help me keep my way of life, and still keeps up with me any details on my case.

    I really appreciated all he did for me.


    Trey is a phenomenal attorney that gets the job done right! He is dedicated to help his clients.

    He made himself available and answered all my concerns immediately! I had faith in him and he continued to prove his expertise by helping me. I highly recommend Trey Porter!!


    Trey Porter fought for me! I am a nurse and thought my career was over.

    Very thankful I got Trey Porter involved. He responds to messages regularly and was very thorough.

    He saved my career. Forever grateful!


    Mr Porter is the real deal. You get what you pay for these days. I know that from my personal business dealings. Attorney Trey Porter was no different.

    He was prompt, professional and poised. I was charged with DWI, and Mr Porter got the charge dismissed. I could not be more pleased or thankful. If you get a DWI, hire the best — hire Trey Porter.
