About GT Law Firm

GT Law Firm combines years of experience and reputation with excellent client service.  Unlike a large law firm, GT clients are people, not numbers.  GT clients have their calls returned quickly, their cases are handled with attention to detail, and they are not passed from one lawyer to the next.

At the GT Law Firm, our advice is free, even if you are still trying to decide what lawyer to hire. We can discuss your options, what other lawyer or law firm you are considering hiring for your case, fee amounts, and any other concern you have to be sure you are hiring the right lawyer for you. We are confident that we are the right fit for your case.

The GT Law Firm represents injured clients and their families with a three point philosopy:


You have to be able to trust the lawyer you hire because a legal matter can be one of the most important and stressful things you will ever go through.

Founder and Principal attorney Guy Thiessen has been recognized by the leading national lawyer rating organization, Martindale-Hubble, as having the highest possible rating for ethical conduct.  Martindale-Hubble rates the ethical standards of lawyers based upon the opinions of other lawyers and judges in the legal community. 



Insurance companies and their lawyers know which injury attorneys have superior legal and courtroom skills, and often decide how much to pay injured people based upon the lawyer representing them.

Guy has represented injured clients and their families for almost 25 years.  By handling hundreds of cases in and out of the courtroom, he has demonstrated exceptional legal and courtroom skills recognized by insurance companies, lawyers, and judges. The leading national lawyer rating organization, Martindale-Hubble rates Guys as an AV, the highest possible rating for legal ability and skill.

Guy has also served as President of Oklahoma’s trial lawyer organization, Oklahoma Association for Justice.



Communication is important. A client should have their calls returned promptly and have things explained in simple terms.

All too often large law firms fail to keep clients informed about their case or fail to return telephone calls or email.  As a smaller firm, GT Law is more accessible to their clients and better able to keep clients informed about what is happening in their case. They strive to return client calls and messages within 24 hours, and much sooner if the matter is urgent.
