Anthony W.

GT Law Firm worked hard to help me with my case. Guy Thiessen never gave up and went above and beyond to help me and my family. Guy is compassionate and cares about the people he represents. We are forever grateful to him and his staff.

Christina W.

I am so happy Guy was recommended to me. He was very compassionate to our family during a very difficult time following an accident. He listened to all of our questions and concerns and guided us through every step of the process. He is very easy to talk to and treated us like family. I would definitely recommend Guy to anyone in need of an attorney! Thanks GT Law firm for all your help!!


I was glad I hired Guy Thiessen and GT Law Firm to deal with the insurance company for the person that hit my car and caused me injury. Guy forced them to take responsibility and we got my claim resolved quicker than I thought.
