Excellent Attorney

Highly recommend Mr. Diaz. His confidence in his ability to have a lawsuit against us dismissed gave us peace of mind during a stressful time. It was not a matter of IF he would win it was just a matter of WHEN. He handily defeated the opposing council in one court appearance. Very thankful to have h...ad him on our side.

Excellent attorney

I have hired Mark on a number of occasions. He is very communicative which is important to me in these situations. He is honest and gives you all the information you need to make an informed decision. I highly recommend Mark and use him exclusively when I require these types of services. I have alway...s had great results when using Mark.

Amazing Attorneys

I hired Katy Jo Muncie with the Diaz firm who handled the lead on my 2 DWI charges in different counties. Along with Mark Diaz, Katy Jo was there for me every step of the way. After firing my first attorney, I was very nervous about what my outcome would be. Katy Jo was patient and worked the sys...tem ultimately getting, what in my opinion, was the best outcome for me in the cases. These cases involved a lot multiple D.A.s and judges, different counties and courts, Texas DPS, etc. I would highly recommend the services of these two fine people. You will be treated with respect and can have the confidence that they know the people and have the experience to get the best outcome. Thank you Katy Jo.

Experience Counts!

We were so grateful to have Mark Diaz in our corner when we needed him. We had no experience with the judicial system, and it was a comfort to know that Mark had experience and first hand knowledge of the judges and prosecutors. It gave us great comfort to know that he was navigating us through thi...s process.

Very easy to work with!

Throughout my trials Mark Diaz and Katy Jo Muncie worked side by side and handled my case with ease. Aside from initiating my first consultation over the phone and making my appearances to court, I held zero responsibility throughout the process. When my case was settled, my DWI charge was reduced to... Obstruction of Highway, and I blew double the legal alcohol limit for my BAC test. I will definitely recommend Mark or Katy Jo if anyone I know needs an attorney in the future.

"I met Mr. Diaz my first time fighting for defendants in custody. He helped teach me how I could maintain my client's individual dignity in a place that so often discards it. The fact that such a passionate and knowledgeable attorney was fighting for misdemeanor custody cases shows that he cares and fights for every single client, no matter what. I fully endorse him."

  • 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.
