I did my homework prior to interviewing/hiring lawyers and mark is well known as a dwi specialist who is great in court. I did not want anotet competent but complacent old lawyer who just tries to get you the best deal possible and cash your checks.
This is not mark. He told me day one that he wasn't interested in getting me a plea deal... Just dismissal or trial. He didn't promise anything but I could tell immediatley and throughout that he was confident in his courtroom abilites and was almost relishing the idea of taking this case to trial.
After several resets I got a Christmas suprise: my case was being dismissed. I am sure that marks reputation with the ADA had alot to do with this. These pretrial negotiations seem to be alot like a poker game. The Prosecutors knew mark wasn't bluffing and was holding the cards to win in trial. This is what I feel set him apart from lawyers I've hired in the past... Everyone knew he wasn't just fishing for a better plea deal and was happy to take this case to court. I read that he has the highest winning percentage of any dwi lawyer in Houston and would use him again and have reccomended him to everyone I know.

Having several friends who have had DWI's in the past, I had a few recommendations for lawyers to evaluate. After meeting with all of them I knew Mark was the best choice. He was knowledgeable, honest, had a can-do attitude and left me with no questions or worries when I left his office. After selecting Mark, I was quickly reassured when I spoke with several lawyer acquaintances that spoke highly of him and read a positive mention in the Houston Press about his win percentage.
Despite the circumstances, my experience could not have been better. The DWI charge was dismissed! Everyone in the court room knew Mark and he had a great rapport with the judge and DA's associated with my case. I plan to recommend him to others in the future if I ever have the opportunity.

I had an excellent experience with Mark Thiessen. I went to his office after recieving a DWI and was in a meeting with him within five minutes of checking in. After a few standard questions and chatting for a few minutes I felt complete trust that he would represent me well. The process itself was just as smooth, I recieved up to minute updates on my case and was never confused about what was going on. I didn't give Mark an easy case to win but he kept us both positive. When we went to trial he dominated the courtroom and kept me involved on every decision, even so much so I finally said your the expert you make the call. The jury was clearly responsive when he spoke and we got the verdict we wanted when it was all over. He's an excellent lawer that will work extremely hard on your behalf, do not hesitate to hire his services.

Mark Thiessen is one of the top DWI lawyers in the country. He is a highly aggressive and effective trial lawyer. He fights harder than anyone I know. He routinely speaks and teaches other lawyers about DWI related issues. He consistently gets cases dismissed and not guilty verdicts at trial. If I was ever in trouble, I would want Mark Thiessen representing me. I enthusiastically endorse this lawyer.

Mark is a skilled attorney. He's personable and persuasive, two essential traits for defending a case to a jury. One of the "not guilty" verdicts he obtained that I heard about was shocking considering that it appeared to be an open and shut case for the prosecution. A truly gifted advocate.
