Patricia I.

I will forever be grateful to Guy. He's a very compassionate person. He's the only one who cared enough to listen to me. Who took the time to investigate and help me find the peace I needed. He fights for the underdog. The world needs more people like him.

Tammy T.

GT law firm represented my family very well in our wrongful death case. Mr. Thiessen is very personable and extremely knowledgeable of the laws in Oklahoma. He was always available to answer our questions and kept us up to date on the progress of our case. I would highly recommend him to anyone that needed a great lawyer!

Cindy S.
