Aggressive lawyer at Houstons best firm

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 wa...sn'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.

Deserves your complete trust

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 ju...st 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.

DWI

I was arrested for DWI. Mr. Thiessen did an excellent job representing me. He was very upfront and kept me informed. He answered all of my many questions. My case was dismissed after almost a year.

Outstanding

Although the experience of having a DWI case was not pleasant in itself, however the experience of working with Mark to resolve it was. Me and Mark worked on this case for about 1 year to finally walk out with a great success. From day one, Mark inspired a great deal of confidence. This was emph...asized by the respectful relationship he had with fellow lawyers at the court house and all the court staff including the judges. Mark always kept me very well informed and made sure I clearly understood all the options that I had. I am not at all familiar with the American legal system. Mark made sure to always clearly explain the process. My case was quite a difficult case, it was therefore a difficult decision to make to go to trial. I dont think many lawyers would've tried. But Mark studied the case very carefully, and finally came extremely well prepared. The trial days were in a way very impressive. Most people come with a plan A, and a plan B in mind. Mark had a plan C and a plan D. He simply was not going to lose this case. Everyone was really impressed by Mark's professional performance in the Court Room. You could see it in the eyes of the jury panel. Mark had the necessary references and knew all of them by heart. I learned so many things that day. The whole experience was great. It was not an easy case at all, and the DAs were really not letting go, quite the opposite actually. But plan A worked, and we didn't even have to go to other plans I wish Mark a lot of success. He is a gentleman with a lot of ethics and certainly puts the right focus when it comes to his work. He is already one of the most successful DWI lawyers, and in my mind, there is not doubt why
