You need an aggressive Houston DWI attorney

Even a first driving while intoxicated (DWI) offense can have serious consequences. In Houston, a driver convicted of a first DWI may face:

  • Fine up to $2,000
  • 3 to 180 days in jail
  • License suspension for 1 year

A surcharge of $1,000 per year may also be assessed by the Texas Department of Public Safety (DPS), or $2,000 per year if your blood alcohol concentration (BAC) was .16 or greater. And if your BAC is greater than a 0.15, the case may be enhanced to a Class A Misdemeanor, which doubles the range of punishment and fines.

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.

Act fast if you've been charged with DWI or DUI in Texas. Here’s something you might not see from other Houston DWI Lawyer websites: If you've been arrested for a DWI or DUI in the state of Texas, you are facing two cases against you. The first one is the criminal case by the state of Texas, and the other is by the Texas Department of Public Safety to suspend your license.

How we fight for first DWI offenders in Houston, TX

With breath and blood test evidence, not to mention field sobriety test results, challenging DWI charges is no easy task. Our team is up to the challenge. We are armed with the expertise and information it takes to identify and expose violations of testing protocol, inherent issues with DWI tests, and violations of your constitutional rights. Our trial record of over 100 Not Guilty verdicts speaks for itself.

We ask the right questions:

  • Did the arresting officer have probable cause to pull you over in the first place?
  • Were you read your Miranda rights?
  • What factors influenced the validity of blood/breath test results?
  • Should breath/blood test evidence be rendered inadmissible?

We know how to challenge DWI charges:

  • Fighting blood and breath tests with science: While blood and breath tests are bandied about as being the ultimate proof of your guilt, the trust is that both types of tests (but especially breath tests) have accuracy issues. That’s why we say the common adage “Do Not Blow” is actually pretty bad advice. Mark Thiessen is not only a Houston DWI defense specialist but an ACS-CHAL Forensic Lawyer-Scientist as well. That means that Mark is specially equipped to identify and fight against invalid and/or inadmissible blood and breath test evidence.
  • Defending your rights during traffic stops and beyond: Simply put, the police don’t always do exactly what they should. This can mean anything from not reading you your Miranda rights to searching your vehicle without probable cause to drawing your blood without a warrant while you’re passed out in the hospital (the latter of which happened in one of our recent cases, Texas v. TP). At Thiessen Law Firm, we know your rights during a traffic stop and, if those rights were violated, we can argue that issue in court.
  • Establishing time of intoxication and fault: In many DWI cases, especially those involving those accidents and intoxication manslaughter, it’s important to establish when you were intoxicated. For example, if it cannot be proven beyond a reasonable doubt that you were intoxicated at the time of a deadly accident, a jury shouldn’t convict you for intoxication manslaughter. Also important in cases involving crashes and death is determining the fault of the accident; if the accident wasn’t your fault or was unavoidable, DWI or intoxication manslaughter charges might not apply.
  • Our reputation precedes us: Thiessen Law Firm is a well-established and highly regarded law firm and home to one of the most renowned DWI lawyers in all of Texas, Mark Thiessen. We have built a strong reputation in the justice system and fierce connections with top subject matter experts throughout both Houston and the state.
