I met Mark at Axion Labs in Chicago this June. We both took the ACS Driving Under the Influence of Drug Course. This course was very intense and it taught us all we needed to know about the pharmacology in drug DUI cases. At the conclusion of the course Mark took a very hard 100 question test to become Certified Lawyer-Scientists through the American Chemical Society. Mark of course passed with flying colors and he is only one of 12 Certified Lawyer-Scientists in the ENTIRE COUNTRY. This is how dedicated Mark is to his craft and to helping people accused of driving under the influence. Not only is Mark highly skilled and knowledgeable, he also teaches other lawyers how to properly defend DUI cases. There are very few qualified lawyers like Mark in the country let alone in Texas.

I met this talented lawyer about two years ago at advanced training for DUI lawyers regarding blood testing and GCMS. This attorney knows his stuff, is a certified lawyer-scientest, and defends people as if he himself is on trial. He has passion for his clients and his cases. There is nothing this attorney won't ethically do to defend his clients. I highly recommend this attorney as a DWI defense attorney.

Attorney Mark Thiessen is the go to guy for DWI/DUI cases in Texas! Mark is a knowledgeable and aggressive lawyer. Some lawyers are aggressive, but not so smart. Some lawyers are smart, but, not aggressive. Mark has both. Also, Mark is passionate about what he does. I highly recommend him!
