Don't take our word for it - here's what our clients are saying

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!

Jackquelyn K.

I was searching for an attorney because my mother was injured in a nursing home due to negligence. A family friend referred me to Guy. When I met Guy, I felt very comfortable and knew he was trustworthy. He was professional and personable from our first consultation until the case was settled. Guy made a difficult time less stressful. I would definitely recommend him to anyone needing legal services.

Cindy S.

Everyone at this law firm was incredible. Guy was very professional and dependable. It is such a relief to know that I have a lawyer I can trust.
