not guilty

State v. P.I.

Harris #13

9/10/19

Attorney: Mark Thiessen

.215 BREATH TEST!! For 19 months and 13 days we fought for this client’s freedom. And I have known this client for 20 years so it was a very emotional trial. While I don’t want a friend to go anywhere else because I know no one will care for them better, it’s hard having their freedom and future in your hands. Client is a local restaurant and bar owner. One morning at 3am after closing one of his bars he was pulled over doing 85mph on I10. He pulled over safely and timely. The officer stated that he smelled alcohol, because client admitted to consuming 5 drinks over his 15 hour shift, with the last drink being with his team as they closed up for the night. The client was cooperative, polite and coherent the entire time. He looked normal on his field sobriety tests. We knew the number was off due to calibration records and our expert was ready to testify as such. However, she did not have to because the officer violated the 15 minute observation period prior to administering the breath test. The technical supervisor admitted this was a violation of the Texas Administrative code that requires strict compliance. As such, the result and slip were properly suppressed by Judge Rodriguez according to TCCP 38.23: Texas’ Exclusionary Rule. At this point we thought he ADA would honor his gentleman’s agreement that he made prior to trial to dismiss the case if the breath test was suppressed. Prior to trial he admitted that he did not have much of a case without the breath test. Keep in mind for weeks I had heard this ADA was excited about our trial and an opportunity to try a case against me. I even told him I heard that prior to our agreement. He promised he was only out for justice and not trial experience and would do the right thing. Well when push came to shove, he reneged on our deal and refused to dismiss. My intern even heard the Pre-Trial discussion. The Judge and entire court heard my tirade against the ADA for his lack of character. After an hour lunch he said I could complain to his boss. I told him, I didn’t need his boss doing the right thing, it was his character that I will never trust again and told him to get back in the court and finish closing this case. Thankfully the jury held the State to their burden and returned a swift two word verdict. They agreed the State failed to exclude any and all reasonable doubt, as outlined in their jury charge, and they had tons of doubt. They also agreed the client appeared normal on the standard field sobriety tests after hearing how meticulous the tests were. It was a sigh of relief to return the client to his daughter without being labeled a criminal. Thank you to the Jury for remaining true to your doubts and holding the State to their burden. Thank you to the Judge for running a fair and just trial. And thanks to God for bringing all these pieces together at the right times. Justice is never served by risking a person’s freedom and good name by trying a weak case just so a DA can get trial experience. His name and reputation is forever tarnished in my book.

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

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.”

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.

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 !!

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.

DWI client

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.”

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.

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!

Mark Thiessen is a Jedi Master of his craft

“Mark Thiessen is a Jedi Master of his craft. Mark and his team have a keen and tactical approach to handling your case, yet still manage to maintain a lot of empathy in their communication with you. A rare combination indeed.

They definitely made this process of navigating the court system as smooth as it could possible be. Things such as answering my texts late at night even on the weekends, and being there in person at the office for meetings were quite clutch.

I am more than glad I went with Mark and his firm when I was a lost pup browsing the endless aisles of law firms showing up via google, ads, family recommendations, etc. Cheers to the Thiessen Law Firm.”

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.

Mark Thiessen Has The “IT” Factor

Often times we hear about how Michael Jordan or Tom Brady just have/had that “IT” factor. In the sporting world the “IT” factor will win you games and championships. In the work world the “IT” factor will earn you praise, money, pretty girls/or guys if that’s your preference and MONEY….. When it comes to the LAW and the “IT” factor; it can mean your freedom or justice. We often take our freedoms for granted and find ourselves on the other side of the law. In that case we have to rely on a lawyer to defend our rights when we or someone else violates our freedoms. In my case, my freedom was violated when an intoxicated group of people decided to gang up on me at a house party in what I would consider a nice part of Houston. Never would I have thought that I would have to defend my freedom and safety in a situation that didn’t seem threatening.

Unfortunately when people drink too much and overindulge themselves in liquid courage anything is possible. Being attacked from behind with verbal and physical assault, I had to defend myself and make split-second decisions. So I ended up having to punch my attacker several times while being attacked by his group of friends. People got hurt, by the grace of GOD I was able to escape the carnage to live another day. Without knowing who attacked me or anyone else at the party other than the few people I came with. I had no idea who to mention when I called the cops to file a police report. Six months after the altercation I was issued a warrant for my arrest from the person who attacked me. Now, most people would wonder how that is possible. I sure did!. I wondered how I could be attacked and assaulted by several people just to be the one the cops or the law came after. The person who I defended myself against investigated me on Facebook and was able to file charges against me. Great idea when you think about it right? Well, I didn’t have a clue who anyone was and when I tried to find out no one seemed to know who this group of people were…

So who do you call in this situation??? Someone you trust? Someone who will fight for your rights? Someone who understands the results of the loss of Freedom and what it can do to your family? Someone who will go up against all the odds and take on a challenge that most lawyers wouldn’t even touch? Someone who you can count on in the clutch? Someone who when the chips are stacked up against you will fight tooth and nail for you? Last but most importantly has the “IT’ Factor!!! If you want to know the answer, just call Mark Thiessen!… That’s who I called and wouldn’t have had it any other way. My case took about 2 years to finally resolve. Mark’s advice was spot on and every step he took was a step in the right direction. When at some points I would question his judgment, his knowledge would turn to be more prophetic. During Trial, he operated the courtroom with charisma and respect. His ability to connect with the Jury on a personal level was amazing! Throughout the entire process I always felt Mark had my back, and in my heart and mind knew I had the right person defending myself. Mark is said to be a up and coming lawyer amongst his peers. In my mind, he is already worthy of being considered one of the Big Guns in this town. You don’t go to war without your gun, so why take a BB Gun when you can take the biggest and baddest gun you can find!
