If you want aggressive criminal defense, hire Mark. He delegates only the mundane to others and is very knowledgable, passionate and professional. Mark grilled the arresting officer on probable cause at the civil hearing to determine whether or not I'd lose my license for refusing a breathalyzer, a...nd the judge found that there was no legal cause for being stopped. As a result, I kept my license, and Mark was able to use this finding in the criminal pretrial meetings with the DA to get a plea bargain to a lesser offense in spite of the video evidence of the arrest that was very unfavorable to my case. I truly believe I'll never need Mark's services again; however, if you do, call him. He's not the cheapest, but he is one of, if not the, best criminal defense lawyers in Houston.

I found Mark Thiessen through several of my friends , I was having serious issues with the lawyer I had at the time he kept telling me I was going to jail when I had done nothing he did not believe me , and I believe he was gonna have me put in jail and not fight for my innocence from the moment I m...et Mark Thiessen I knew he was going to do everything for me to keep me from that horrid jail , I was not aloud to leave my county he drove all the way up to the woodlands to meet me at starbucks to speak on my case he got all the charges against me dropped within minutes he's truly the best lawyer ,he has a lot of respect from his piers including the judge that actually told me I was very lucky to have such a great lawyer , and trust me I know I was lucky to have found him , and that is the gods honest truth if you want a GREAT lawyer Mark Thiessen is your man .

I would HIGHLY recommend hiring Mark Thiessen as your attorney for any criminal case that you have received in the Harris County area. He is extremely knowledgeable of the court system and what actions can be taken pre-trial in order to have the best outcome at your court date. I was put on probation... for a DWI a year previous to hiring Mark as my attorney. I failed to complete the requirements in order to get off of probation. My probation was revoked and sent back to the courts. That's when I hired Mark. He told me to go complete the rest of the requirements for probation and get myself a court date. When we got to court he persuaded the judge not only to dismiss my probation, but dismiss it successfully. In court he made small talk with the judge and prosecutor which told me that he knew them and had a good relationship with them. Which was not the case for other attorneys that went in front of this judge. Again you can't go wrong hiring Mark. He is great attorney and great person.

If ever in the unfortunate position where one needs a lawyer, I can not recommend Mr. Thiessen enough. He is a highly skilled and knowledgable attorney and I had a very favorable result due to his diligence and expertise. . He and his entire staff are caring, compassionate and do everything they ...can to relieve you of the stress and worry involved with a court case.
