Client Testimonials

Client

★★★★★

I highly recommend Guy Thiessen. He helped my mom in a wrongful death case against an assisted living facility. He is extremely experienced and knowledgeable in these type of cases and is able to swiftly zero in on the significant issues. He is very ethical and well respected in the legal community. He listened to our concerns and helped us achieve an excellent resolution.

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. Respectfully - Diane Jackson

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!

Client

★★★★★

I had a personal injury case involving my young son with Guy Thiessen representing our case. He worked very diligently on the case to make sure our concerned voices were heard by the other party and the court. Our voices were definitely heard and I could not be more appreciative of his hard work. I would definitely recommend him and his office and if anything occurs in the future I will not hesitate to use his services again.

Client

★★★★★

I am so glad we used Guy Thiessen as our lawyer. He is down to earth and approachable. He was always honest with us and we could communicate with him easily at all times. We never had any doubts about working with him. When I was searching for a lawyer, one of the things that impressed me most was that he called me personally and not one of his staff. I spoke with several law firms and just the fact that he made me feel like he cared meant the world. Other firms would have an underling talk to me to see if it was worth the lawyers time. Guy took control of the case immediately. I would highly recommend him and his firm to all of my friends and family. You will have someone in your corner that cares.
