Why would you choose anyone else?

My name is Michael & I'm a 19 year old college student with a big future ahead of him. Back in April of 2014 I chose to drive while intoxicated and I put myself in jail by doing so. My BAC was 0.16 twice the limit and I had very little hope for my future to come. Well in November of the same year, I ...went to court fearing that I would be put behind bars, put on probation, have a huge fine, or much worse. Well Mark managed to paint a beautiful picture to the Judge allowing him to acknowledge my age, future, and guilt. By doing so, the judge gave me 1 year license suspension, no fine, no jail time, no probation. Now leading up to the case Mark managed to keep me feeling positive about the outcome do to his confidence, attitude, ambition, knowledge, and frankly the man knew what he was doing. Needless to say, I'm very pleased that I chose Mark Theissen to represent me, as I would recommend him to anyone in the same troubles as I was.

Houston's BEST DWI/DUI ATTORNEY!! HANDS DOWN, DO NOT HESITATE TO GO WITH MARK!!

To be caught in a DWI case is a very serious matter and endangerment to one's future. Initially, I had gone with another lawyer, but he actually recommended that I should go with Mark instead. To put it all in perspective, I was facing a dwi first offense with a 0.158 blood. I knew I had to fight... it because my future direly depended on it. Mark was very informative with the whole process. He is truly not afraid of going to trial. During my many times in court, I saw many pleas and lawyers that were afraid to try a dwi blood case, but not Mark. The reason why he is one of the, if not the, best DWI attorney in town is just that. All the way from his charisma to his courage, He will fight for you until the very end. As predicted, my case went to trial. It would have been an even scarier two days if Mark was not by my side. To be able to watch him in action is a work of art. His craft in trying cases is unmatched. Literally, there were other lawyers watching him so they could learn a thing or two. We had hired an expert for the defense and when Mark had the stage, it was very harmonious. It's almost difficult describing just how good Mark is. You can really tell that he has put in the effort to perfect his trade. He is like the Michael Jordan of trial lawyers. With Mark on your team, that's when your chances of winning are greatest. He caught the prosecution's witnesses lying multiple times and ultimately, the floor belonged to him. He just has the right characteristics of the type of people who are great in the respective fields. To tie everything together, God forbid you are ever caught in a DWI case, but if you are, Mark is the guy. There is no other way around it. You have to be completely honest with yourself and realize that this guy is the most winningest DWI lawyer in town. That, in itself, should be a testament to his work ethic, knowledge, and bravery. Trust me when I say this, that he WILL FIGHT for you. The prosecution objected to almost everything he wanted to bring out, but Mark objected to one thing only. That goes to show how he is able to set up the battlefield in the defense's favor.

DWI case

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.

The Best Lawyer in the Industry

I chose Mark Thiessen to represent me in a DUI / DWI case and it was the best selection/decision that I could have made. I found out about Mark through Internet search and reached out to him and his office. Upon meeting with Mark - I immediately knew that he was the right lawyer/attorney to represent... me and give me the best opportunity to win my case. Mark is an expert attorney with a work ethic that is second to none. He is always available. He is a master of his craft and will give you the best opportunity to win your case. He will be prepared and he will do everything to ensure your case is won. He will actually be more knowledgable on the aspects of law, facts of the case, than the individuals that have accused you of your offense. He was highly successful in my case, even despite some of the alleged facts not being in my favor. We won the case and all charges were dropped. Thanks Mark!
