Hall of fame-esque Lawyer

My experience with the Thiessen Law Firm was absolutely amazing. Mr. Mark Thiessen had an in depth conversation with me regarding my case, and laid everything out to me, so I was able to understand my situation clearly. They provided me with very well thought out plans of action, and were awesome in ...being my representation. Even Mr. Thiessen's paralegal, Erin Dubose, was awesome to work with! Everyone kept me very well informed on what was occurring with my case, and they were always able to help me feel at ease, as I felt my case was in the hands of the absolute best in the business. Although I may have started panicking at times (who doesn't haha), I was able to rest knowing who I had helping me through my whole ordeal. I would highly recommend Mr. Thiessen, or any of his other amazing associate attorneys with any legal issue. I have absolutely no regrets teaming up with Mr. Thiessen, and I am glad I was able to get the outcome I desired. They were also just awesome people to talk to, as I loved their sense of humor, and I appreciate Mr. Thiessen and his entire team for everything they did for me. I would give more than 5 stars if it was possible. If you want the best, go with the Thiessen Law Firm because if they can't help you then I'm not sure anyone can!

Top of the Elite & Honest

Mr. Mark Thiessen is not only the top of the elite superlawyers in his profession but one of the most honest people I have ever met. After explaining the details of my case, Mr. Thiessen could have easily taken my payment and moved along, yet knowing the details and background of my case he suggested... I hire another attorney within his firm at a lesser payment, saving me money. I was blown away and have the utmost respect for this man. Immediately hired on his associate within the firm, but respect and will give credit where it is due. Thank you again Mark, you have all my recommendations and respect!!!

Excellent Attorney!

I was charged for DWI in 2021. After talking to multiple attorneys, I decided to go with Mark. He was very knowledgeable, honest about my chances, and had exceptional records. His assistants, especially Donna, were excellent. With his help, I was accepted for the Pre-trial program. In the end, the ca...se was dismissed!

Best Lawyer In Texas

I received my second dwi while on trial for another and Mark was able to get my SECOND dwi dismissed without have me having to show up to court. I travel for work so this helped out a great deal. The Thiessen law firm staff was very responsive and kept me up to date every step of the way. Mark was ev...en able to work out a payment arrangement, so I didn’t have to pay for everything upfront. I 10/10 recommend Mark Thiessen and his staff for any dwi case.
