WHEN YOUR FUTURE IS AT STAKE YOU DON'T NEED A LAWYER WHO WILL TAKE YOUR CASE, YOU NEED ONE TO WIN IT. 1 OF ONLY 2 CRIMINAL LAWYERS TO BE NAMED TOP 100 SUPER LAWYERS IN ALL OF TEXAS. THE ONLY DWI ATTORNEY TO MAKE TOP 100 SUPER LAWYERS IN HOUSTON AND/OR TEXAS. AND, OVER 100 NOT GUILTY VERDICTS!

Born and raised in Houston, Texas.  Went off to college at TCU and came back home for law school.  I know Houston.  I am raising my family in Houston.  I love Houston.  It's my job to protect the citizens of Houston. 

Having long had strong ties to the greater Aspen area, my wife and fellow attorney Taly and I have opened a second office in Aspen. We look forward to bringing the results we have been achieving for over a decade in Houston to the people of Aspen!

 My favorite part of this job is going to trial.  And, it's that love of trial that gets great results before a trial is necessary.  Too often the State will try and force you into a deal.  Let me analyze the case.  Let me analyze the State.  The State has the burden of proof to prove that you committed that crime beyond a reasonable doubt.  Don't go down without taking a swing of the bat.  But, it's best to bring the biggest bat you can carry. 

I live by my word and will always be straight with you.  When you hire me, I will give you my cell phone number and you can call/text/email me at any time.  Afterall, I work for you.

Mark Thiessen is a criminal defense all-star. If he can’t get you a win, nobody can.
Simply put, Mark Thiessen is a criminal defense all-star. If he can’t get you a win, nobody can. I’ve worked with Mark and his team on two very different cases, and both times I’ve been blown away by the level of honesty, strategy, and respect that Thiessen Law Firm brings to the table. You can feel the difference the second you step in the courtroom with Mark by your side. The time he has taken to build relationships and earn respect is clear. He knows how to push the envelope while still being respectful of the system when it matters. Best of all, he knows where the “win” is, even when “not guilty” isn’t possible. He won’t send you to trial when he knows it won’t work, and he won’t just roll over and charge you for the same lame deal everyone gets. Mark and his team carefully look at every angle and every opportunity to protect your freedom, keeping you informed and engaged at every step of the way. In my case, that meant helping me avoid expensive restitution fees and probation requirements. I’ve seen other people go into the system for similar charges with cheaper defense and the difference is night and day. If you want to handle your case with as little impact on your life as possible, Mark Thiessen is the man to call.

DWI G.O.A.T "Greatest of all time"
Mark Thiessen is the BEST attorney money can buy and worth every penny! He helped me get my life back on track and I cant thank him enough! I got a DWI in Montgomery county, one of the worst county's for DWI's. The chances of your case getting dismissed or the charges dropped when you go to this court are slim to none. I had applied for the PTD program but they denied approval. After that my mom who is an Attorney from Brownsville, Tx hired Mark Thiessen to represent me, she has known Mark through ongoing DWI seminars and knew that he was the best fit to get this case dismissed or even to reduce the charges. But getting the charges reduced did not interest Mark. His relentless determination to win, is the very reason my case was found not guilty. Thiessen is an amazing lawyer and it was truly thrilling to see his ambition and determination in the court room. Mark Thiessen is the best lawyer money can buy and I would refer him to all of my family, friends, and anyone in need of the best attorney in Houston! Mark Thiessen is the true G.O.A.T in criminal defense.

The Man, The Myth, The Legend
I am a medical Professional that has been working in the operating room since 2008, so when I was wrongly accused and my career was on the line, I called the best: Mark Thiessen. Mark came highly referred to me from me back in 2009 when he was learning his trade at the top law firm at the time. After reading his reviews on line and meeting him in his office, I knew I could trust Mark to fight for me. Every time he walks in the court the DAs, Judge and staff all greet him like we was at their dinner table over the weekend. When Mark would walk in the court house, i would perk up to watch and analyze him because he took over the room. He knew everyone’s name, their kids name, and what questions to ask to make them feel special. I had a very complex case with some tough issues, but Mark didn’t give up. He told me: if they want to label you a criminal and cost you your career, they can find you guilty over my dead body. We set it for trial and Mark showed up very ready every time. The State actually dismissed my case before trial due to my opinion, they rather not loose to Mark... I was so excited but, I kind of wanted to see Mark in trial. The guy is a beast. Side note: a year later, I got to see Mark in trial as he won my brother’s best friend’s trial. Every time I see that friend, he shakes my hand and we both know that introduction to Mark saves his career as well. His whole heart and soul goes into whatever he tells you he will do. He’s a fighter for sure. Hire Mark when you can’t afford to lose. He’s the best. Thank you, Mark, for saving my innocence, my friends trust and being the friend and Attorney that has my back. You are honestly on my speed dial!! Best to you and yours! Sincerely, Beau D

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 case 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 even 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.

Best Attorney
My husband hired Mark to defend him after he was charged with a DWI. Even with evidence against him, Mark got the DWI dismissed. He was in constant communication with my husband through the whole process, and kept his mind at ease. We would 100% recommend Mark.

Professional and Personable
There are plenty of options when seeking legal counsel in Houston. I met with many to decide who would be best to represent me. Needing legal help was new to me and made me quite anxious. After speaking to Mr. Thiessen, I felt comfortable with his representation. He was personable and professional and I could tell he had tons of experience. His team was helpful and easy to reach if I had any questions. Overall, I am glad I picked this firm to represent me. I would highly recommend meeting with Mr. Thiessen if you need legal help!

No Half Measures - Mark is the right lawyer for you - Case Dismissed
If you're here, you already know that you need a lawyer. The next hurdle is figuring out who to hire. From my friends who referred Mark, to my own personal experience, I can tell you that Mark is right answer for your legal problems. He will fight for you and get you the best possible outcome. You really get to see how different of a lawyer Mark is when you see him in the court room. When the other lawyers are asking your lawyer for advice, you know you made the right choice. In the end, Mark reviewed all the angles of my case and ultimately got my case dismissed. From the receptionist, to his paralegal Donna, and Mark Thiessen himself, the entire team is top notch in helping you navigate your legal issues.

Criminal Defense Case Dismissed!!
My case started in December 2019 two years ago I got charged with a felony. Throughout this pandemic our court dates have been pushed back non stop My attorney Mark Thiessen told me he was going to treat this case like I'm his brother and he wasn't going to stop trying and pushing this case till he gets us to an agreement we all agreed upon. Two years and my Attorney Mark Thiessen fought this case and finally came upon an agreement with the District Attorney and came up with a dismissal but I had to do 90days of PTI well we waited at the court house and when he came in came right back out and told me he was able to fully dismiss the case with no PTI. This attorney is literally hands down the best attorney you can count on to handle your case you're in good hands when it comes to Thiessen law firm trust me you won't regret any bit of it I wanted to thank you Mr.Thiessen for not letting me and my family down throughout this pandemic the time it took paid off with Thiessen Law Firm!!

I hired Mark Thiessen for my case. He took care of my ARL hearing, took care of all court issues, and I only had to show up once. That's when he told me I was done, everything is dismissed!! I would recommend him to any family, friend or stranger in need!! He's professional and gets the job done!!

He's Da Man
He managed to handle a deal to dismiss 3 felonies, in lieu of pleading for a misdemeanor, whether these were true charges or not it didn't matter, I was hoping to keep a clean slate though, but overall the deal was good, I know the county gotta get something too.

Incredible lawyer
Making the call on my case was never one I wanted to make, but I clearly made the correct decision in calling Mark. He was confident from the start and told me that he would get it handled. After attending court a few times I felt things may not happen like I would like. Then out of the blue a call from his team telling me that Mark had got my case dismissed and everything was over!

"Mark Thiessen is the GOAT in DUI & DWI law. Only a fool would face a DWI charge without Mark by your side."
DUI and DWI Attorney | Dec 10
Relationship: Worked for lawyer
"I was a career prosecutor until I retired. I knew Mark way back when and knew him to be special at what he does. He knew it all then and does so now, as well. He is not afraid to make the state prove its case. He is the only lawyer I know who is triple board-certified in DWI law and is a Lawyer-Scientist...Now, as a defense attorney and having the opportunity to watch him teach other lawyers all over the state, it is cemented in my mind... He is one of a kind."
DUI and DWI Attorney | May 21
Relationship: Co-worker
"Mark is known as one of the best of the best in not just DWI defense but criminal law as well in the legal community throughout the state of Texas. He's helped me elevate my skills as a trial lawyer, fight aggressively and relentlessly for our clients, and always has his door open for advise. I'm honored to have him as a mentor. He's a great lawyer and even better person."

"Yes, he's my husband. But the best and hardest working attorney I know! Look at his stats, they speak for themselves."
Criminal defense Attorney | Apr 16
Relationship: Worked together on matter
"Mark recently honored the Iowa Association for Justice (aka Iowa Trial Lawyers Association) as a guest speaker. The greats give back to the legal profession not expecting anything in return. He simply hopes to raise the bar for everyone. Mark did not disappoint. He flew into Iowa on a red eye and spoke the following day for over two hours. Mark could have spoken for the entire day as he captivated a room of accomplished trial lawyers. He is energetic and commands a mastery of OWI/DUI defense. As important to his control of a dynamic area of the law he extremely personable. I am happy to call him a friend. He would be at the top of my list to defend a serious criminal matter in the great state of Texas!"
DUI and DWI Attorney | Jul 30
Relationship: Fellow lawyer in community
"If I ever have a DWI, I would hire Mark!"
DUI and DWI Attorney | Apr 18
Relationship: Fellow lawyer in community
"Mark Thiessen is one of the top DWI lawyers in the country. He is a highly aggressive and effective trial lawyer. He fights harder than anyone I know. He routinely speaks and teaches other lawyers about DWI related issues. He consistently gets cases dismissed and not guilty verdicts at trial. If I was ever in trouble, I would want Mark Thiessen representing me. I enthusiastically endorse this lawyer."
Criminal defense Attorney | Mar 09
Relationship: Fellow lawyer in community
"Mark is a skilled attorney. He's personable and persuasive, two essential traits for defending a case to a jury. One of the "not guilty" verdicts he obtained that I heard about was shocking considering that it appeared to be an open and shut case for the prosecution. A truly gifted advocate."
DUI and DWI Attorney | Dec 04
Relationship: Fellow lawyer in community
"Mark is an exceptional lawyer and fights hard for his clients. Whenever I can, I try to either watch Mark defend his clients in court or learn from him in CLEs. This year alone, Mark beat down a case where a client was charged with 4 counts of felony intox. manslaughter and 1 count intox. assault. This is in addition to the mountain of acquittals he has under his belt. I would recommend Mark to anyone in need of a criminal defense attorney."

"The best DWI lawyer in Texas!"
DUI and DWI Attorney | Nov 02

"Mark Thiessen is a "Lawyer's Lawyer". In other words, lawyers call him for advice. He is one of the most respected DWI Lawyers in the United States."
DUI and DWI Attorney | Oct 19
Relationship: Fellow lawyer in community
"Mark's results speak for themselves. What nobody sees on his Facebook page or website is what he does for fellow attorneys. I've personally only met Mark on one occasion, but I've talked to him on the phone and exchanged emails numerous times for advice and questions on cases. To me, a persons actions outside of the public view are the best barometer of their true character. My first time talking to Mark was before I even met him. He was working late on a Friday and I had some questions on an upcoming case. After finishing his work day, he took time out of his personal time to walk me through my questions. If someone is willing to do that for a complete stranger, without recognition, imagine the job he will do for your case."
DUI and DWI Attorney | Mar 03
Relationship: Worked together on matter
"Mark is one of the best there is in the State of Texas for defending DWI cases."
DUI and DWI Attorney | Feb 15
Relationship: Fellow lawyer in community
"I knew Mark when I was in the Houston area from 2010 to 2015. Mark is easily among the top 5 DWI Attorneys in the State. He is routinely invited to lecture at Texas Criminal Defense Lawyer seminars. I observed Mark speak to a Jury Panel for Jury Selection during a misdemeanor DWI trial. The prosecutors were so intimated by Mark that they constantly objected--during Jury Selection! Objections are not very common during Jury Selection. The Judge was cautioning Mark in response to these objections (she was partial to the State). The objections were pretty silly and designed to disrupt Mark's speaking to the Jury. Mark confidently responded to the Judge's comments and resumed speaking to the Jury Panel. I learned something very valuable from Mark that day. When you are good like Mark, prosecutors fear you and this is obvious to the Jury. Mark's reputation as the best results in Not Guilty Verdics for his clients. He wins. Period."
Criminal defense Attorney | Nov 19
Relationship: Opposing Counsel on matter
"As a former prosecutor, you always knew that when Mark walked through the door you were in for a fight if you went to trial. He knows his stuff, especially DWI law."
Criminal defense Attorney | Sep 09
Relationship: Fellow lawyer in community
"There are many great trial lawyers in Texas and there are many great DWI lawyers in Texas. What really sets Mark apart from the rest of the pack is his ability to be both. Mark has some of the most thorough understanding of all aspects of DWI cases, from the science involved to the applicable laws. Usually, more technical lawyers who understand the science or the law do not also excel in connecting with the common juror or in explaining difficult concepts to a jury or judge. Mark Thiessen is able to bridge this gap very successfully: his trial results clearly speak to this ability. I'm a board certified criminal trial attorney with over a decade of experience and multiple trials under my belt and I still learn and pick up a few tricks when watching Mark in trial or when he speaks at continuing legal education events. I endorse Mark Thiessen - he knows what he's doing."
DUI and DWI Attorney | Jul 15
Relationship: Fellow lawyer in community
"I highly endorse Attorney Thiessen. He is a powerhouse in the field of DUI Defense. Well educated, highly skilled, aggressive trial lawyer. The type of lawyer that does not roll over! You need a fighter? Mark is your man!"
Unknown Attorney | Jun 09

DUI and DWI Attorney | Mar 21
Relationship: Fellow lawyer in community
"I endorse this lawyer. Need a not guilty? Then this is the lawyer to call. I've known Mark for nearly four years and I've never seen him plead a case. When winning is what's important then this is who you need. Not only are you hiring a consummate professional you'll also be hiring a super nice person."
DUI and DWI Attorney | Mar 03

"If you want one of the best DWI attorneys in Houston... Scratch that... in Texas - Call Mark Thiessen. Unparalleled dedication and commitment to his craft. Highly recommend."
