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.

Tracy T.

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.

Tina W.

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.

I want to thank the GT Law Firm for everything they have done for me! They made my settlement quick and simple. They were super friendly, very professional, and they always responded almost instantly. I recommend the GT Law Firm to anyone who case a case or claim that needs to be settled.

Teresa G.

Our case was against a Nursing Home for negligence, causing an untimely death. We were extremely impressed by Guy Thiessen and his staff. They answered all our questions timely any we were able to call them whenever we needed and/or wanted. They were thorough in getting the information needed, which resulted in a successful outcome. I pray that we never have to do something like this again, but if we do, we will definitely call Guy.

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.

Martha S.

Guy is very professional. He helped guide me through the legal services I needed, and followed up every step of the way. Highly recommended!

Chrissy C.

Guy worked tirelessly for my mom. My mom was a victim of severe nursing home abuse and neglect that in the end cost her, her life. When I first met with Guy and explained what had gone on and expressed the guilt I carried he was so kind and reassuring and explained that this is not acceptable and should be addressed. He fought for what was right and in the end helped to vindicate my moms death. I would hire Guy again in an instant, you will not find another attorney with the integrity and fight that Guy has.

Christina W.

Jonathan F.

Mr. Thiessen, was very upfront and helpful, throughout settling my non fault motorcycle accident. There were a couple hiccups, but he had nothing to do with them, it was all on the insurance companies.


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.
