Thiessen is the ONLY choice for DWI/DUI Cases

If you're facing a drinking charge, don't shop around, call Mark immediately. Mark Thiessen leaves nothing in the bullpen, he approaches every aspect of a case and tries to visualize angles that the defense may use. In addition to being extremely knowledgeable in the realm of DWI/DUI cases, he's e...xtremely personable and doesn't throw around so much legal jargon that you're head is left spinning after a meeting. Mark will do everything in his power to help you out; his goal is to get you something you're comfortable with and doesn't settle for less. He demands honesty and respect, and returns the favor. Possibly one of his greatest assets is that he's created a reputation and rapport with many colleagues and uses that to his advantage. His confidence can sometimes be a little zealous, but it motivates him at the same time. Being charged with a Felony Intox Assault with a deadly weapon (and looking at 10 years felony probation or 4 years in prison) was a terrifying experience. I was referred to Mark by an attorney friend who had heard him lecture, calling Mark was the best decision I made. Mark fought hard for me; in the midst of a Judge/DA turnover, a summer full of drunk driving cases, and amounting issues with the complaining party, Mark was able to successfully have charges reduced to a misdemeanor DWI and 2 years probation, a feat even the Judge was impressed by. Mark entered as a lawyer, but quickly made it into the ranks of friend. He has my highest recommendation and I will be sending any friends who experience the nightmare of a drunk driving case his way.

Mark Thiessen a outstanding attorney that will fight to the end

Mr. Thiessen fought every step of the way to ensure justice would prevail. Despite all the adversity from the unprofessionalism from the Harris County court two, Mark didn't quit fighting for me. I would highly recommend Mr. Thiessen and his associates to anyone looking for a dedicated and knowledg...eable attorney.

Wonderful Attorney

Mark was great, he is the kind of attorney that you dream of. He and his staff were helpful, attentive, knowledgeable, and very professional. He, along with his team, were there for me in every sense of the word. I truly felt like they cared about me and my well-being. Mark was outstanding in cou...rt, from the jury selection all the way to the closing arguments. He is very smart and was able to challenge the science of the prosecution's expert witness just on cross examination. He has the charisma needed to win over jurors, but also the professionalism needed to maintain the highest of standards. If you want to win your case and you want the peace of mind knowing that you are in good hands, Mark is your guy. He is relentless in his approach and will ensure you are represented fully. I would recommend Mark Thiessen everyday.

Best DUI/DWI Lawyer

I owe Mark Thiessen allot after what he did for me. He's a pitbull of a lawyer. Mark fought for me from the beginning and all the way through my slip ups. Mark knows how, and will get you the best possible option there is. I know this because I sat in the court room as he relentlessly took on the Ass...istant DA and the judge, not backing down for 5 solid full minutes until he had worked out what I wanted as his client. Mark Thiessen isn't lazy, nor does he hide behind fancy jargon, nor will he quit.

Montgomery county DUI

Mark is a great attorney and I would highly recommend him to anyone needing a great defense. Mark knew all the procedures, took time to memorize jurors by name and highlighted all the mistakes in the arrest. Mark cares about his clients and puts forth 110% in the courtroom.
