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.

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.

In one word – Fantastic

I am in my late forties and was in a bit of legal trouble for the first time in my life. It is a very stressful time for somebody who is going thru this first time. First the arrest then going through the booking process and finally spending 8-9 hours waiting to be released. Once I got out I started my research on what to do to minimize the impact. My charge was failure to ID to a police officer (a class B misdemeanor – lets just say I was in the wrong place at the wrong time and when an officer showed up i panicked and did not want to give my ID in front of people who were being questioned for possession of drugs.

Anyway i got a few references of lawyers and started going and meeting the lawyers and also doing internet research on them as well as on my pending charge.
Since this was my first offense – i was hopeful that I would qualify for either pretrial intervention program or deferred adjudication with a very slim outside chance of outright dismissal.

From my internet research I was able to gather that Mark was an outstanding lawyer and his reviews were excellent but mostly in the area of DWI.

All the lawyers I met were setting me up for the first two outcomes mentioned above and nobody wanted to entertain the possibility of outright dismissal. When I met Mark I was instantly impressed. He heard my account of the event, got very candid account of the events out of me by making me feel comfortable. He then gave a very detailed idea of what the approach and strategy he was going to employ. He also let me know that there were a few unknowns (the offense report being one) based on which he will tweak his strategy on game day. I was sold and signed up.

On the court day – As per strategy Mark came is very late when all other dockets were done. Being a Friday Mark likes to dress in funky clothes which he calls his fun day clothes. Everybody in the court know this and looks forward to him making an appearance. Having been through a lot of trials most of which he ends up winning he knows all the DA and court staff. He had the best presentation of all the lawyer that I saw in the court ( and I had an opportunity to see them all since Mark came at the end). He is also well respected in the court.

We went over the offense report and Mark immediately decided that he was going to go for an outright dismissal. I was a still not sure if this will work but he went in to talk to the ADA and then DA and convinced them that it was not worth their time to fight this one. I believe that part of this comes from the fact that everybody know Mark’s reputation for being a tough aggressive lawyer not afraid to go to trial for his clients. I was ecstatic at the outcome whereby not only was the charge dismissed but also I would not have to go through probation for a year or more and then having to wait to get my record sealed or expunged. I am now eligible for immediate filing for expungement proceedings which will remove all traces of my arrest and my court date.

Mark was the most expensive of all the lawyers that I talked to but he was worth every penny. When you really need somebody to defend you I recommend you go hire Mark Thiessen. I will keep his contact handy for the rest of my life.

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.”

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.

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.

Michelle

DWI Client

I recommend Mark Thiessen

Bonjour.

Je tiens à apporter ici le témoignage de mon entière satisfaction concernant l’action menée par Maitre Thiessen au cour de l’instruction préalable à mon procès devant la cour criminelle du comté de Harrys.

Je me suis fait arrêté par la police et contrôlé positif à l’éthylomètre au volant. Ceci est considéré comme un crime au Texas. Après avoir passé deux jours en prison j’ai été relâché sous caution et j’ai pris contact avec Maitre Thiessen sur les conseils d’un collègue de travail. Maitre Thiessen était connu de mon collègue après une conférence qu’il avait faite au sein de l’entreprise afin d’exposer et d’expliquer les lois en vigueur au Texas auprès des expatriés. (je n’étais malheureusement pas présent le jour de cette conférence !)

Pendant toute l’instruction, Maitre Thiessen m’a expliquer le déroulement de l’affaire et m’a tenu informé des éléments pouvant être évoqués en ma faveur au cours d’un futur procès ainsi que ceux à charge, présentés par l’accusation. Il a surtout mis en œuvre tous les moyens dont il pouvait disposer afin de contester les preuves présentées par la défense. De plus me trouvant un peu perdu face à l’ampleur que prenait ce procès, qui pour nous français semble démesurée, je tiens à souligner aussi l’importance du support moral que m’a apporté Maitre Thiessen.

Nous sommes allés jusqu’au procès. Le jour du procès l’absence de l’interprète prévus pour m’assister a fait que l’audience a été reportée. Maitre Thiessen a profité de cette opportunité pour présenter au procureur et à ses assistants les derniers éléments de preuve collectés par l’expert qu’il avait employé afin de vérifier les mesures prises à l’aide de l’éthylomètre. Ce relevé montrait des mesures erratiques et montrait que l’appareil avait été mis au rebus quinze jours après mon contrôle . Ces éléments de preuve ont convaincus l’accusation que les charges à mon encontre ne tiendraient pas devant un jury et les poursuites furent abandonnées.

En conclusion, si par malheur vous vous trouvez impliquer dans un procès pour conduite en état d’ivresse, je vous conseille d’avoir le réflexe de contacter Maitre Mark Thiessen pour votre défense !!

Mark eres mi hombre que luchó por mi libertad y justicia!!!

La desafortunada noche que por causa de un accidente automobilistico, fue detenida, evaluada por un oficial de la policia y luego arrestada bajo cargos erroneos de Manejo en Estado de Ebriedad (DWI) o bajo la influencia de alcohol, fue la peor noche de mi vida.

Al haberte resistido a tomar la prueba de respiratoria evidencial en un fin de semana el cual era digtado como “Sin Derecho a Refutir” dicha prueba, determinó el derecho del estado a una prueba de sangre al ser encarserada. Estos resultados de sangre fueron sumamente altos al ser recibidos, lo cual significaron el problema mas transcendente de mi vida, afectando mi carrera profesional al punto de descenso absoluto, y descalificame como aplicante para recibir mi ciudadania Americana, la cual ya era factible por mi tiempo siendo residente legal de este pais.

Dada la seriedad de mi caso, hize una investigación intensa para contratar un abogado con experiencia extensa en casos de DWI, y con gran fortuna encontré al abogado que salvó mi vida, no sé que hubiese sido de mi sin Mark Thiessen. No solo Mark tomó un caso casi imposible de ganar en una corte tribunal, llevandome de la mano, ofreciendo su apoyo incondicional a cualquier hora del dia o noche, pero tuvo la extraordinaria abilidad y competencia para ganar el caso y salir triunfante!

El jurado me encontró no culpable, gracias a mi angel de la guarda, Mark Thiessen. No tengo palabras para expresar mi agradecimiento y por el constante apoyo y fortaleza que Mark y su equipo legal me ofrecieron durante el agonizante período que tomó mi caso por resolverse.

Puedo garantizar, que bajo la abilidad extraordinaria, experiencia incomparable y destreza de la ley, puedo recomendar a Mark Thiessen con ojos cerrados a cualquiera que se encuentre en una situación desesperada como la que yo tuve que pasar.

Mark, eres mi heroe y siempre te recordaré y recomendaré como el hombre que luchó por mi libertad y justicia!!!

Mis gracias infinitas!

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!

His knowledge of the legal system was astounding

After being arrested for a first time DWI, I felt scared, lost, and worst of all alone. I quickly started asking around and reading reviews. Time and time again the name Mark Thiessen was the main constant to every conversation or search. He, himself, called me back in less than 24-hours, set up a consultation the next day, answered all my outrageous questions patiently, and proceeded to give me an overview of how the process would play out. His knowledge of the legal system was astounding. Everyone knows DWI’s will come with a price tag as well. But I felt the price and payment plan were very reasonable, especially when your talking about your own future. You get what you pay for and WOW! I got that and even more through the process. Some people’s minds work systematically, if A happens then B. Not Mr. Thiessen. He was a wild card throughout it all and thinking outside the box. His rapport in the courtroom was always unmatched. Might I add this was at a time of the changing of the guards and all new judges that most lawyers were not too familiar. My judge already had known of Mr. Thiessen. After everything was said and done with evidence, I believe I came out with the best possible scenario for my case. As I’m finishing out my last few months of PTI, I think back and know I wouldn’t have gotten here with out Mr. Thiessen’s help. Thank you! I would highly recommend Mr. Thiessen to anyone I know and urge anyone reading this to do the same.

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!

Thank you, Mark, for saving my career

“I’m in medical sales, 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 my friends. 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. I was honestly proud that was my lawyer when he came in.

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. The State actually dismissed my case before trial. 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.  His whole heart and soul goes into it. 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 career.”
