Attorney Profile

Recognized throughout Texas as one of the top criminal and DWI defense attorneys in the Houston area, Mark R. Thiessen prides himself on representing his clients aggressively in court and with caring outside the courtroom. With The Thiessen Law Firm, Mr. Thiessen concentrates his practice on defense in DWI and controlled substances cases.

Mr. Thiessen has been honored with the top AV Preeminent* rating by the Martindale-Hubbell peer-review process and received a 10/10 “Superb” rating by Avvo. The American Institute of DUI/DWI Attorneys named him as one of the 10 best attorneys for the state of Texas.

A competitor in sports and martial arts during his days off, Mr. Thiessen brings that competitive spirit to the courtroom as well. At the same time, representing clients against DWI charges can require the skills of a scientist, and so Mr. Thiessen also brings a working knowledge of the chemistry and anatomy of blood alcohol concentration tests.

A native of Houston, Mr. Thiessen maintains deep ties to the community. A graduate of The Kinkaid School, Texas Christian University and South Texas College of Law, Mr. Thiessen practiced civil law for three years before becoming a criminal defense trial attorney. He has served as the chair of the DWI Committee for the Texas Criminal Defense Lawyers Association and on the board of directors for the Harris County Criminal Lawyers Association. Texas Monthly named Mr. Thiessen as one of the top young lawyers in Texas and Houstonia magazine named him as one of the top lawyers in criminal defense.

Mr. Thiessen maintains a busy schedule of speaking engagements for educational purposes and professional development, and has been frequently published in professional publications for DWI defense attorneys.

*AV Preeminent and BV Distinguished are certification marks of Reed Elsevier Properties Inc., used in accordance with the Martindale-Hubbell certification procedures, standards and policies. Martindale-Hubbell is the facilitator of a peer review rating process. Ratings reflect the confidential opinions of members of the Bar and the judiciary.
