    I knew Mark when I was in the Houston area from 2010 to 2015. Mark is easily among the top 5 DWI Attorneys in the State. He is routinely invited to lecture at Texas Criminal Defense Lawyer seminars. I observed Mark speak to a Jury Panel for Jury Selection during a misdemeanor DWI trial. The prosecutors were so intimated by Mark that they constantly objected--during Jury Selection! Objections are not very common during Jury Selection. The Judge was cautioning Mark in response to these objections (she was partial to the State). The objections were pretty silly and designed to disrupt Mark's speaking to the Jury. Mark confidently responded to the Judge's comments and resumed speaking to the Jury Panel. I learned something very valuable from Mark that day. When you are good like Mark, prosecutors fear you and this is obvious to the Jury. Mark's reputation as the best results in Not Guilty Verdics for his clients. He wins. Period.

  • Colin Hobbs

    As a former prosecutor, you always knew that when Mark walked through the door you were in for a fight if you went to trial. He knows his stuff, especially DWI law.

  • Joshua Hill

    There are many great trial lawyers in Texas and there are many great DWI lawyers in Texas. What really sets Mark apart from the rest of the pack is his ability to be both. Mark has some of the most thorough understanding of all aspects of DWI cases, from the science involved to the applicable laws. Usually, more technical lawyers who understand the science or the law do not also excel in connecting with the common juror or in explaining difficult concepts to a jury or judge. Mark Thiessen is able to bridge this gap very successfully: his trial results clearly speak to this ability. I'm a board certified criminal trial attorney with over a decade of experience and multiple trials under my belt and I still learn and pick up a few tricks when watching Mark in trial or when he speaks at continuing legal education events. I endorse Mark Thiessen - he knows what he's doing.
