This was the first time I have had a run in with the law and it was a very new frightening and uncertain period for me. Chris was extremely friendly and easy to talk to as well as easily available throughout the whole process. He answered all of my question, of which I had many, and helped guide me through all my options throughout the whole process. I made it through the whole process and he was instrumental in making sure I did what I needed to in order to remain out of trouble and complete my sentence without a hitch and get this incident off my record. I certainly wasn't the easiest client with all my questions and concern, but Chris was always available and answered my endless questions.

Chris is an outstanding attorney. Being that I have never been in any sort of legal trouble, I was reassured through the whole process. Only a six month journey and he was able to get my felony case completely DISMISSED. Not only was the Thiessen Law Firm understanding and helpful they were very professional. I highly recommend Chris to anyone in need.

Chris was very professional and straightforward with me the entire time of my case. I had caught a D.W.I. and didn't know where to turn until I visited the Thiessen law firm. Upon speaking with Chris I knew he was the person I was looking to hire to defend me. Chris was very easy to communicate with and he always called me back if he missed my call. And the results were just what I was looking for when he told me my case was dismissed! I'm not only pleased with the results of my case but the true professionalism of Chris and the rest of the Thiessen law firm are second to none.

Chris Denuna is beyond amazing. Not only did he help resolve my case quickly, he did it so it would benefit me the most. With my case I was worried since day 1 but Chris reassured me that he would handle things and get things done and he did. He always kept an open line of communication and maintain a level of confidence that left me knowing that I don't have anything to worry because I'm being taken care of. Even after the prosecutors were beating around the bush and stringing me along with my case, Chris stood his ground and worked to get it dismissed. Confident, professional, and diligent, I will highly recommend him to anyone without a doubt. -A.L.

When it comes to understanding legal matters and the courts in Houston/Harris County. Chris really knows his way around. What I thought would be a legal nightmare Chris was able to resolved expeditiously and have it dismissed in my favor. I have no hesitation is recommending Chris and Thiessen Law Firm. D.A.

Mark is an exceptional lawyer. There are many lawyers who say they fight for clients but Mark walks the talk. When it comes to training he goes all out as well. I came to know Mark as he and I attended the same training together at Axion Labs in Chicago and we both took the certification test at the same time and successfully passed it becoming Certified Lawyer-Scientists through the American Chemical Society. It was a tough course that comprised of four different hands on scientific courses totaling over 120 hours of training and took two years to complete. There are less than 75 Certified Lawyer-Scientists in the entire country.

I have also had the great privilege of watching Mark speak on scientific issues as well as speak with him at a conference recently. He is an excellent lawyer who will fight for you and who does so because he has received excellent training. I know. I was there when he was learning it. I do not endorse many lawyers but I would trust my freedom with Mark if I was in trouble. You should too.

I contacted Mr. Thiessen at the recommendation of a friend from church who was a former Harris County District Attorney turned Defense Attorney who had seen him in action. I was facing DWI #2 when I asked her to represent me. Knowing the levity of the situation she said, word for word "You need the best, you need Mark Thiessen."

Long story short he has worked with me closely deciding the course of action on my case. When it came time for action, he won my ALR Drivers License hearing right off the bat which means I retained my driving privelage until the outcome of the case and in this case, over 7 months. He always answered my calls, any questions and kept me in the loop of the going on behind the scenes. I never felt as if I were being mishandled and more importantly I never felt lied to. He has a to the point, no bull**** but compassionate demeanor; in other words he won't lie to you or tell you what you want to hear, only what you need to hear.

I was facing jail time, heavy fines, among other things when we were ready to plead. He really wanted to fight my case and never did I feel he wouldn't have been a pit bull the D.A. would have dreaded seeing across the court room. For me, the best choice was to take the plea bargain as I needed to get on with my life. By trying the case it would've likely been after the New Year. With that in mind, Mark negotiated hard with the D.A. and got my black and white, cut and dry DWI #2 case reduced to a Class B misdemeanour from an A. No jail, no probation but only a fine. He also set up my occupational license pathway to stay on the road legally without ever missing a beat. I walked away extremely happy with my experience with Mark. He is a consummate professional.

Long story short... Mark got my case dismissed. It would have been my second DUI. All lawyers say they will fight for you. Mark really means it.

I was dealing with a situation and the Thiessen Law Firm did everything in their power to resolve it. They were with me every step of the way and because of their tenacity, I was able to get past my legal trouble with ease. If it weren’t for their hard work and structured legal help, I would’ve been lost. Look to this firm for any legal help. Great people...Thanks Again.

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.

Dismissed!

Mark and his staff were available to answer my questions all along.

When I saw the smile on Mark’s face as he walked towards me to tell me that the case was dismissed, it was like a huge weight was lifted off of me.

I very much would recommend Theissen Law Firm to defend anyone who would find themselves in my shoes.

Thanks again, Mark, and thanks to your staff.

With his comprehensive legal knowledge and broad courtroom experience, Mark is able to assess the client’s needs from the outset and offer a sense of realistic goals and results. Next, his legal know-how, solid courtroom skills and robust capacity for hard work secure the best outcome available. He is thorough and frank in his feedback, and polite and friendly in his interactions. In short, Mark gets the job done. He is a professional with a true commitment to his work, and I recommend him without reservation.

DISMISSED!
Stellar Lawyer and terrific Law firm!!
Chris Denuna was very professional and extremely courteous. They always kept me well informed about my case and Chris was always available to field my questions and concerns. Not only was he instrumental at getting my case DISMISSED!!!, but he also made me feel like I mattered as an individual, not just a client. Thank you Chris, you have my gratitude and my recommendation for anyone that finds themselves in the same situation as I was in.

I want to say thank you Thiessen Law Firm and special shout out to Mr. Chris Denuna.
You were hitting homeruns with every single pitch the State was throwing us. This is one person you want on your side... He gets straight to it and is knowledgeable. Thank you again Chris!!! You the man !!!

It was a long journey but well worth it in the end. Mark was incredible, and very thorough in exploring all avenues. On the verge of having my second DWI, Mark was able to fight tooth and nail to get it reduced to a reckless driving misdemeanor. Just a fine and no time served. Thank you Mark!

Best law firm in Houston!

Great work! Integrity, honor, and commitment is what this company is all about. I highly recommend this firm!

I hired Chris Denuna for my DWI case earlier this year after my first consultation with him. Chris was very polite and professional at every meeting we had. He really listened to my case and studied it with detail. He mentioned that he had experience in Montgomery county where I had my DWI so that gave me a lot of confidence to know that he really knew what he was doing. The case was dismissed and I am very thankful for his hard work. I would really recommend Chris to my friends and family or anyone who is going through a similar situation.

I don’t really know where to start because there is so many great things to say about my experience with Chris Denuna. My arrest for DWI occurred in August 2018. If you have just been arrested for DWI then you will soon find it can be a confusing, drawn out and a costly offense. Luckily I made the right choice of hiring Chris! I interviewed many people before hiring Chris as my mom has been a paralegal for 30 years. I had the option of going with a family friend or someone older and cheaper but I wanted to sleep at night. First off, The Thiessen Law Firm is about as intimidating of a firm you can get in the Houston area when we are talking DWI defense. Second if you check Avvo rating you will see why you want Chris as he is a wonderful choice, especially for the price. I have an anxiety disorder and the first thing I noticed about Chris was that he put me at ease. Never, not for a moment did he ever talk down to me, nor dismiss a concern or judge me. The thing that stood out the most was empathy and I truly believe that Chris cares about me and my case. He spent countless hours texting back and forth with me, answering questions and concerns to put my mind at ease even when I'm sure I was annoying; because he knew my anxiety issues and treated me according. This made the process sooo much easier because I knew he was going to bat for me. After all this time communicating with Chris I truly consider him a friend. His confidence and knowledge is very apparent when he is speaking with people. And while I did have a concern about his age (he is two years younger then me) I think there is something to be said about hiring someone young enough to have the energy to handle case loads and give you the attention you deserve while making a name for themselves vs someone who is older and not as passionate. He never gave me false hope. He told me my options upfront and was more than fair with pricing. He worked with me because he knew I was unemployed due to the pending case and my line of work. Now for a little bit of background on my case. “Allegedly” I had two accidents (none involving other vehicles) I refused to blow. My blood bca was a 0.11 and it was written in the report that I had a open container and went into a ditch right in front of police. I also have previous marijuana charges from 14 years ago as well as a previous criminal mischief charge. First Chris to told me to go to the DMV ASAP and get a new ID within the correct time frame which is important and went on to win my ALR hearing to keep my license. I wanted to fight it and Chris was up for the challenge. By May 30th 2019 my case was dismissed and all I had to do for terms was a few AA meetings, and a letter from a sponsor, 24hours community service and a DWI education course. He maintains a close relationship with the DA’s and knows the judges, one of which used to be a DWI defense attorney. Chris has already filed the paperwork for expungement as well so it will be wiped out the system completely by the end of August. It’s also worth noting that I spent a lot less even with the expungement then what the average person spends on a DWI case in the long run. You can’t go wrong with Chris if you want wonderful representation with a name that will scare the DA on a budget price for the best DWI firm in Houston. I would 100% hire him again and will be keeping him on speed dial! -JB

Mark & his entire team are absolutely incredible. I couldn’t have found a more dedicated attorney. They all genuinely helped me fight for my freedom for years & never gave up! Mark is a bulldog who never backs down from a fight. It’s like watching an episode of Law & Order the way Mark & Taly conducts themselves in the court room. My family & I were blown away. Trial is a scary experience for anyone but Mark & his team never allowed me to settle for any offer they felt was unfair. It was a very long journey & they were there every step of the way. They made me feel like family. They Went Above & beyond in all aspects. If you’re looking for an attorney I highly highly highly recommend Mark & his team! Money well spent & I would gladly do it all again without hesitation if I had too.

Mark is a top notch professional. He is dedicated, methodical and has impressive knowledge of the law, the people, body language and the influence of others. He is without a doubt somebody I would highly recommend. WE WON!

I was referred to Mark T. by another reputable attorney and was completely at ease and trustful of his ability to handle/win my case the very few minutes of us sitting down. He possesses a very likable, yet forthright and aggressive nature which is what one would ideally seek in a trial attorney for such matters. He is very reputable and knows most of the DAs in Houston. Case was dismissed in a matter of sheer minutes. Would absolutely recommend Mark and his firm! Very professional, yet relatable crew!

I was arrested for a DWI class A during a "no refusal weekend" in Fort Bend County. With Chris's knowledge of traffic laws he was able to win my traffic court case. Being able to maintain my driving privileges during this process meant I could continue providing for my family without any inconvenience. It took over 3yrs of resets in the slow moving legal system of Fort Bend but Chris remained vigilant and professional. He was able to have my case dismissed and I couldn't be more grateful. Words can't describe the feeling of relief knowing I have my normal life back.

Thank you Mr. Denuna!

Chris did an outstanding job handling my case. Unfortunately, I found myself in a situation that required a lawyer, and even though I called at 11 p.m. the night before my court appearance, Chris called me back not even an hour later saying that he would meet me in the morning. He was very patient with all of my questions and made everything very easy to understand. He was always quick to respond to me, whether through texting or phone calls. He handled my case with complete confidence and I never had to feel worried that I was not getting adequate representation. Chris was able to get my case dismissed without ever having to speak to the judge. I would recommend Chris for any criminal attorney needs.

Thiessen Law Firm is the best in the Business! Thiessen Law Firm not only got my DWI case dismissed but made me feel worry free during the duration. If you need a Attorney's you can trust, then put your case in the best hands possible. Thiessen Law Firm! C.F.

I would definitely recommend Chris, he was able to get DWI dismissed. i was very happy about this.

This guy knows his stuff and has skills. Mark spoke to a class that I am part of on how to represent clients. I see a lot of presentations and lawyers and Mark would be my first call if I needed help with a criminal matter; especially anything DWI or DUI related.

Letty McLaughlin gave us a 1 star review. Mark nor TLF has never represented her or anyone associated with her. This is malicious guerilla tactics by our competitors. How we know it’s fake 1. DUI is a ticket, we don’t do tickets. 2. $10k clients have my cell and never complain. 3. It’s very rare a client gets Jail, never on a misdemeanor, and absolutely never if I’m not there. And 4. In about 15 years of practice we’ve had 3 clients that didn’t get along and we refunded their money. We are not in it for the money. We practice law because people need our help. We love fighting for the under dog and treat our clients VIP.

Dan Simons is a part of this law-firm and worked hard for me. Now I fully understand why people say it is worth the money to hire the best! Thanks Dan!

Mark Thiessen is by far one of the most strategic, aggressive attorneys I've encountered. He has done wonders for my DWI case and doesn't back down. I didn't worry once about the outcome of my case with Mark having my back.

When I found out I was facing 2yrs, worried. When I would see Mark Thiessen walk into court room and put his charm to work, priceless. My 2nd DWI case dismissed. Get to spend time with family and eating great instead of bologna sandwiches and inmates. THANK YOU Mark Thiessen!! As a local guide I review burgers and burritos and have amassed .5M views, this is a review that has made an impact on my life for the better. I recommend Mark to my friends and family.

Awesome lawyer and amazing staff! Highly recommend!

My experience with Mark Thiessen and his staff was nothing short of exceptional. He was able to get a DWI I had from 2014 dismissed yesterday. I 100% recommend his services and friendly staff. They were helpful and informative and promptly answered any questions I had regarding my case. Mark himself is very professional he gets the job done with favorable results!
Thanks Thiessen Law Firm for such a great job!

Mark is a great trial attorney. He treated me like a person and not as a paycheck. He's an ambitious person and hates losing so I'm sure he'll fight for you as hard as he did for me. Thanks Mark

Great law firm, great people. Highly recommend

Attorney Mark Thiessen is very knowledgeable. I attended a Continuing Legal Education Seminar that he presented at.

He is also very creative and strategic in his approach to trial.

If you have a DWI/DUI or know someone that faces this charge in Houston, TX, call Mark!

Attorneys who have represented me in the past have treated me as a pay check rushing me through my case with haste. Any regard to me as their client was unsatisfactory. Mark Thiessen on the other hand fought my case aggressively for two years. Answering all my phone calls with questions about my case, in a timely and professional manner. In the end my case was dropped to an obstruction of a highway, a lesser charge. I am completely satisfied with Mark Thiessen. I recommend him to anyone who is in need of an attorney. A professional and true aggressive lawyer is hard to find. I'm glad I found Mr. Thiessen.
Thank you!!!!!
