Hired Attorney Ms. Taly Thiessen

Having made the mistake of getting married in the first place, I needed a divorce. Mrs. Thiessen was amazing from the start. She got me everything and more that I wanted from my ex. She is kind, courteous and tough as nails. The fight was brutal but she fought hard for me and my rights, and won. My ex’s attorney never stood a chance!!

Hired Attorney Mr. Mark R. Thiessen

Mr. Thiessen is by far the best in the business. I was nervous about the whole legal process after my second DWI arrest. He was able to ease my concerns and make me feel comfortable. He took my case to trial and won, not guilty! Meet with no one else, hire no one else!!

Taly Thiessen is an amazing attorney. She was responsive and saved me from going to jail. I even came back to hire her in a divorce issue I needed years later. She is the total package!

Hired Attorney Mr. Mark R. Thiessen

Mark Thiessen represented me in 2020 on my Felony case. I was highly recommended to him and he did not disappoint. Amongst the COVID pandemic, his office was quick to call me back and get me in a consultation the same week. I hired Mark Thiessen the same day. He got the job done, my case was dismissed!!! I would hire Mark Thiessen again in a heartbeat!!

Hired Attorney Ms. Taly Thiessen

Mrs. Thiessen was very fast to help in a dire matter concerning child support. I contacted several attorneys, and they never returned my calls and the few that did wanted to book me for a consult a week later. Mrs. Thiessen's office was quick to get my problem solved in less than 24 hours. Client service is something you just can't appreciate enough. I highly recommend her team as they are the most responsive I have met. I would gladly recommend her office to any of my family and friends.

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.

Hired Attorney Mr. Mark R. Thiessen

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 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. 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. 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.

Hired Attorney Mr. Mark R. Thiessen

He held my case for a year and quit out of nowhere. I was under the impression that my case was solid because of the evidence and the hospital bill i gave him. No one communicated with me for almost 1 year now I'm back to square one. I will never use him again.
