not guilty

DWI 2nd / State v. J.A.

Harris No. 14

9/25/20

Attorney: Ronnie Yeates

NOT GUILTY on .113 BLOOD!! This was the first criminal trial completed after the courts closed in March 2020 due to COVID. For 22 months, the client was adamant he was innocent, and we fought side by side with him to make the State prove their charge. The client was pulled over for speeding. The second question out of the officer’s mouth was “How much have you had to drink tonight?” The Client never stood a chance. He was going to jail. It was 12:10 a.m. Monday morning on the Gulf Freeway when the client was stopped by a veteran, seasoned HPD DWI officer for the single offense of speeding, 92 in a 60-mph zone. The client had his identification and insurance ready for the officer and provided it to him upon request with no problem. The officer said the client had red, glossy eyes, needed support while standing, staggered while walking, and had a strong odor of alcohol coming from his breath. The officer testified he had the client perform one of the Standardized Field Sobriety Tests. However, through cross-examination, the officer eventually testified the test he had the client perform was not done correctly and its validity was affected. The officer also testified, under cross-examination, he did not think the client had lost his normal mental faculties or lost his normal physical faculties; which is the definition of intoxicated. Having elicited honest testimony from the officer, the defense moved for an instructed verdict, and we are thankful for the Judge for following the law and ordering the Jury to find the client Not Guilty. We were happy to give the client the result he deserved and his life back after almost two years of fighting.

This is the only lawyer you should choose for your peace of mind

Good evening, it took me a long time but finally I can actually express the sentiments I felt from the beginning of my nightmare to the end of it with leaps of joy.

This is not a paid comment or was I ever asked to do it, from the beginning where you feel like the whole world is dark and you don’t see any light at the end of the tunnel, everyone at the Thiessen Law Firm welcomed me and my family but most importantly they were clear in their answers to the many questions I had.

Never doubted on a positive outcome as I could see their expertise and the way they would be relaxed and calm on going about their business as if you were watching a perfectly synced movie!

Ultimately Mr. Thiessen, Mr. Denuna and Ms. Bedru, all came through for my case and the most incredible thing was having my case dismissed.

I am at a loss of words as well as I would hope I could write a more detailed message!

THIS IS THE ONLY LAWYER YOU SHOULD CHOOSE FOR YOUR PEACE OF MIND!

I will always be grateful for having God put you in my path Mr. Thiessen!

Thank you always to you and your firm!

I couldn’t have gone with a better law firm

I have to start off by saying how thankful I am that my case was dismissed. I never thought I would need a criminal lawyer but life happens. Mark kept me informed during the entire process. My case was rescheduled a few times, which was incredibly frustrating, but Mark kept calm. He had a game plan from start to finish. I couldn’t have gone with a better law firm.

I knew within 10 seconds after meeting Mark that he was going to be the attorney representing me in my case.

If you do not hire Mark Thiessen to represent you in your DWI case, then you will be making a huge mistake that could personally and professionally follow you around for the rest of your life. I aggressively shopped law firms online and interviewed numerous attorneys before I met with Mark. I knew within 10 seconds after meeting Mark that he was going to be the attorney representing me in my case.

Mark is a very knowledgeable, tough, no nonsense kind of guy. I cannot begin to tell you how important this is because the legal process is a tough roller coaster ride that will beat you down. Knowing that Mark was watching my back thru the process was a huge help beyond any description.

Even with Mark leading the charge, I honestly thought my chances of receiving anything less than a full conviction were rather slim because my case is what is referred to as a “blood case” and nobody beats a blood case (or so I thought). I also had a firearm unlawful carry charge (even though I had a conceal carry permit), so I was expecting the worse. Fortunately, Mark saw otherwise. I still remember the day he called me to tell me the unlawful carry charge had been dropped and the DUI case was reduced to 12 month deferred adjudication for reckless driving.

Lastly, Mark’s staff was at all times 100% professional and committed to providing the best service to their clients. I was always treated with the utmost respect and was always kept informed of the progress with my case. I hope you never have to go thru the process I had to endure, but if you get into legal trouble, call Mark.

The BEST Attorney in Harris County and Probably One of the Best in the Nation

Mark Thiessen is by far the BEST attorney in Harris County and probably one of the best in the nation. His firm is extremely polite and professional. Mark and his staff were always there for me when I had questions or concerns. He was able to get my DWI dismissed in Harris County which is a huge relief. I would highly recommend Mark for any DWI or drug related case.

They turned what seemed like an impossible case into something with an unexpectedly amazing outcome

The Thiessen Law Firm is a top firm with excellent attorneys. They work with criminal law, personal injury law, and family law. They are ranked one of the top law firms in Houston for a reason. Mark Thiessen is a very knowledgeable, honest, and trustworthy attorney. He and his associates work very hard, and are readily available anytime you need them. They fight for their clients yet maintain a polite and respectable manner in the courtroom. For me, they turned what seemed like an impossible case into something with an unexpectedly amazing outcome. I would highly recommend Mark Thiessen and the Thiessen Law Firm to anyone who is looking for trusted and diligent legal representation

If You Want a GREAT Lawyer, Mark Thiessen is Your Man

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 met Mark Thiessen, I knew he was going to do everything for me to keep me from that horrid jail. I was not allowed 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.

Amazing, Reliable and Superb Attorney! The Great Mark Deserves 100% Marks

Mark achieved everything that I thought wasn’t possible. He overcame every obstacle that the DA threw at him, approached the case with confidence, and ultimately claimed a victory for me. I am incredibly grateful for Mark Thiessen.

It was the best decision I could have made

I’m a lawyer. I made a mistake one night and was arrested for suspicion of DWI. As a lawyer, it’s extremely difficult to trust your case to another lawyer. It’s ingrained in your bones to want to be in control, but you can’t because no matter what you’ve read on the internet or seen on TV, you don’t know that area of law, or the criminal judges, or the prosecutors, and the reality is all of that really matters. You have to find an attorney you can trust to protect your interests. Mark was the first and only lawyer I called to handle my DWI case, and it was the best decision I could have made. He and his team exceeded all of my expectations in getting both my ALR and DWI dismissed. I went to him because of his reputation among lawyers at being the best at what he does, and I wasn’t disappointed.

My case is now dismissed and I can finally put this all behind me.

I am a professional business leader part of a Fortune 1,000 company. A year and a half ago my mother has just diagnosed with stage four ovarian cancer. At 8 pm on a Thursday night my stepdad called and told me that she had been rushed to the medical center.

I made a terrible decision!!

To get in my car to be there for my mother. I was pulled over and charged with Driving while intoxication. Never being faced with anything like this, I did not where to turn for help. I called a friend that had gone through something very similar in the past and she without hesitation told me to call Mark, she gave me his cell phone number and within 24 hours I was sitting in his office. He was very honest and sympathetic to my situation. He took my case and we went through the process. He always told me that he had my back and that I should take care of my mom. He would say, “I got this”.

He was very professional and gave me great advice. My Mom passed this last August and though this was a horrible mistake I was still able to be with my Mom until the end. My case is now dismissed and I can finally put this all behind me thanks to Mark and his professional team.

If Mark 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.

Excellent Attorney to Have Represent You

Because of the seriousness of my case (serious for me), I had been researching and meeting with many different lawyers in the area. I felt like my life was unfairly ruined; I even considered pleading guilty just because it seemed the odds were against me. What made me choose Mark was not only his positive reviews and great record, but when I first met him he was confident, honest, straightforward and very knowledgeable. He definitely knows what he’s doing and will fight for you. Mark will not fudge or sugarcoat the situation to you. While some people may take it as not caring, it is exactly was is needed in this type of environment. I appreciated that he was very honest and gave all the details to keep me informed throughout the entire ordeal.

I ended up getting both Mark and Jed Silverman to represent me. It felt like I was getting two of the best lawyers in Texas to represent me; however, it was more like getting them and their entire staff in my corner. The team was very helpful and kept me informed at each court appearance, especially Mark Metzger. The case dragged on for a good while, which was very nerve-racking for me, but in the end it was worth it. At the last court appearance, the prosecutor did not want to let up and seemed it was going to go to trial, but Mark Thiessen was very “persuasive” and worked his magic, and to my surprise got my case dismissed. While I was scared it may have gone to trial, I felt Mark was the best man for the job had it gone down that road.

While his services may not be the cheapest to some, you get what you paid for in this field and Mark seems to be very high in demand. I highly recommend Mark Thiessen, it was worth every penny!

You Cannot Compare Anybody with Mr.Mark!

I was accused by my own wife. It was a painful incident happened in my life. She said to the police that I was threatening to kill her and beaten her. She did this to be because she was looking for lot of money from me and I couldn’t give her the money. She was so bad that she even made proofs with the doctors. There was witness from Doctors and nurses and even some voice recordings. She allowed the doctors and nurses even to record our loud conversions. There were lot of accuses on me and the case was very strong. But in front of Mark nothing can stand.

I had just two resets and the time. The first one was just a day adjustment and the next one was just 2 weeks. On the second reset, I went to the court and heard shocking news. My wife again called the court and said that I was threatening her again. This created huge complications. Because of this they gave the reset after 4 months. I am a frequent traveler to other countries and I was worried. On the very same day Mark comforted me with his words. He said ‘just keep quiet and wait for 10 days, I will get this dismissed’. I really believed him because he says and does what will really happen. It was just seven days later I heard from Mark that he has my dismissal in hand and no convictions. It was a big surprise that he did it in a lightning speed. With all my heart I thank you Mark.

You cannot compare anybody with Mr.Mark. The way he handled the case was really great. He knows the tricks, tact tics and he is really great in his profession. I suggest when you are in a real problem you definitely need Mark with you.

Respectfully,
A loyal client
