  • I recommend Mark Thiessen.
  • I hired Mark 6-12 months ago.
  • Mark handled my DUI / DWI matter.
  • I have previously worked with no lawyers.

If you're facing a drinking charge, don't shop around, call Mark immediately. Mark Thiessen leaves nothing in the bullpen, he approaches every aspect of a case and tries to visualize angles that the defense may use. In addition to being extremely knowledgeable in the realm of DWI/DUI cases, he's extremely personable and doesn't throw around so much legal jargon that you're head is left spinning after a meeting. Mark will do everything in his power to help you out; his goal is to get you something you're comfortable with and doesn't settle for less. He demands honesty and respect, and returns the favor. Possibly one of his greatest assets is that he's created a reputation and rapport with many colleagues and uses that to his advantage. His confidence can sometimes be a little zealous, but it motivates him at the same time. Being charged with a Felony Intox Assault with a deadly weapon (and looking at 10 years felony probation or 4 years in prison) was a terrifying experience. I was referred to Mark by an attorney friend who had heard him lecture, calling Mark was the best decision I made. Mark fought hard for me; in the midst of a Judge/DA turnover, a summer full of drunk driving cases, and amounting issues with the complaining party, Mark was able to successfully have charges reduced to a misdemeanor DWI and 2 years probation, a feat even the Judge was impressed by. Mark entered as a lawyer, but quickly made it into the ranks of friend. He has my highest recommendation and I will be sending any friends who experience the nightmare of a drunk driving case his way.

It pays to have a top notch attorney!

  • I recommend Mark Thiessen.
  • I hired Mark 1-6 months ago.
  • Mark handled my DUI / DWI matter.
  • I have previously worked with 1-2 lawyers.

In 2012, I was charged with DUI. The arrest did not involve any material evidence of unsafe driving nor did it involve an accident. Unfortunately, the breathalyzer indicated a .09 alcohol content. I hired a reputable Houston attorney, but he gave me little hope of winning the case. After more than six months of resets and reminders that it was going to be a tough case to win, I did some research and hired Mark Thiessen. Because of Mark's expertise, diligence and attention to detail, the case was ultimately dismissed due to lack of evidence.

Mark Thiessen a outstanding attorney that will fight to the end

Mr. Thiessen fought every step of the way to ensure justice would prevail. Despite all the adversity from the unprofessionalism from the Harris County court two, Mark didn't quit fighting for me. I would highly recommend Mr. Thiessen and his associates to anyone looking for a dedicated and knowledgeable attorney.

  • I recommend Mark Thiessen.
  • I hired Mark 6-12 months ago.
  • Mark handled my DUI / DWI matter.
  • I have previously worked with 1-2 lawyers.

I am embarrassed to say that I got arrested for DUI (no accidents) on 2 occasions in the last 2 1/2 years. The first one was for .08 BAC and like an idiot, i submitted to the field sobriety test and breathalizer. At that time i engaged a very high profile DUI firm in Houston and they assigned the case to one of their associates, Mark Thiessen. My first instinct was to enter a guily plea due to the extra costs of going to trial. However, Mark convinced me to go forward to trial and the ultimately the case was dismissed just days before trial!! Two years later i got pulled over again and refused the field tests. I was forced to give a blood test by court order and BAC was .10. Obviously i called Mark Thiessen again and now he has his own firm. Once again I was hesitant to go trial due to the extra costs involved and once again Mark convinced me to to go to trial. The day of trial Mark got the case dismissed again!!! I wont go into the details, but what he did was both genius and gutsy. I also have a feeling that the DA's office both loves Mark and fears going to trial against him, given his record of trial experience and continuing education. So for me, Mark Thiessen is "two for two". Perfect batting average and obviolusly i would highly recommend his firm to anyone. I would also advise anyone to follow his advice if and when it is to go to trial. If i would have plead guilty to both of those charges, i would like lbe in jail right now. One bit of advice for anyone who is fortunate enough to get a DUI case dismissed......spend the money to immiediately get the DUI expunged (remove) from your record.

Wonderful Attorney

Mark was great, he is the kind of attorney that you dream of. He and his staff were helpful, attentive, knowledgeable, and very professional. He, along with his team, were there for me in every sense of the word. I truly felt like they cared about me and my well-being. Mark was outstanding in court, from the jury selection all the way to the closing arguments. He is very smart and was able to challenge the science of the prosecution's expert witness just on cross examination. He has the charisma needed to win over jurors, but also the professionalism needed to maintain the highest of standards. If you want to win your case and you want the peace of mind knowing that you are in good hands, Mark is your guy. He is relentless in his approach and will ensure you are represented fully. I would recommend Mark Thiessen everyday.

  • I recommend Mark Thiessen.

  • Mark handled my DUI / DWI matter.
  • I have previously worked with no lawyers.

Our daughter was arrested for felony DWI with child, and all she had done was stop to render aid to a drunken driver who had overturned her car. When the ambulance had taken the driver of the overturned car to the hospital, the attending officer arrested our daughter on suspension of driving drunk herself ( which she wasn't). Mr Thiessen was successful in getting a no bill from the Grand Jury. Had this not have happened my daughter could have been sentenced to three years in the correctional facility and her life would have been ruined. We will be eternally grateful to Mr Thiessen for his knowledge and ability to correct this horrific error. Thank God for Mark Thiessen!!!

Often times we hear about how Micheal 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 over indulge 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 month after the altercation I was issued a warrant for my arrest from the person who attcked 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!

Mark worked on my case very recently and I was very impress with his work ethic, how professional he was and how hard he would work for a client. I would definitely refer him to anyone because he is not your typical lawyer that goes for your money but instead cares about his client. Thank you Mark for getting me a second chance in life. I owe you for everything that you did for me and because of you my ex-fiancé and I are friends again............
