Mark did an outstanding job from start to finish in my case. After being arrested, I had court 24 hours later. I called Mark the day I was released and he was in court with me the next day. My case was not an easy one due to what was on my record previously. To begin with I ended up in Felony cou...rt when I should have been in a lesser court. Mark got that fixed immediately and had my case assigned to the proper court. Secondly, the arresting officer in the case convinced me to blow at the station. I blew a 0.18. When I heard the number that night I knew I had screwed up. That being said, Mark took my case from Felony court with a breath sample of 0.18 and got my case completely DISMISSED. Nothing on my record at all. Mark was prompt in court and responsive to all my calls and emails. He made the whole situation very simple and told me exactly what I needed to do and gave perfect advice throughout the process. I would recommend Mark for any defense needs you may have.

I inquired about Mark's services because he was highly recommended to me by a friend. Mark was extremely helpful from the very beginning in explaining the legal process and what to expect. It was obvious that Mark was very well respected in the courtroom. My was case eventually dismissed and I couldn...'t have been happier with the decision to hire Mr. Thiessen.

I am a 20 something profession who got in over my head with a DWI arrest. Mark supported me throughout the whole process and ended up getting my case dismissed. Without him I would have had to put my life on hold but he went above and beyond to see that I could continue with my future plans and not h...ave this on my record. I thouroughly reccomend him.

You probably came across this site the same way I did, by frantically searching for someone who will help you or your loved one out of an unfortunate circumstance. You found the person that will do just that. We originally hired a different lawyer who we knew of but after a couple of months it beca...me clear that he did not specialize in DWI cases. After some research and several phone calls we found Mark Thiessen. After the first telephone conversation with Mark, my husband said “this is the guy I want representing me”. He was even more convinced after we met Mark in his office. My husband’s English is not great and I asked him if he was sure that he didn’t want a Spanish speaking attorney. He said “no”. If you happen to be going through this it is a frustrating experience. You’re supposed to be innocent until proven guilty but it feels more like you’re guilty until you can prove yourself innocent or creatively weasel your way out of it. It is a game and you want the best player on your team, Mark is that player. He knows the law, he knows the ins and outs of the breathalyzer machine, he knows the people in the court room, he was very dedicated to helping us and he listened to what we had to say. He never promised us a dismissal, after all, this was my husband’s second DWI (the first one was in 1999), and even though he looked great on the video during the field sobriety test his breath test was .13, but that is exactly what we got MOTION TO DISMISS! Thank you Mark for all you did, we are so grateful.

I made the mistake of driving the wrong way on a one way after a few drinks in downtown Houston. Mark was able to win my license revoction hearing then got my cased dismissed. While doing this, I made another huge mistake and got arrested again in Anahuac where Mark was able to gain a dismissal as ...well. He pulled two miracles out and represented me extremely well. I highly recommend him!
