About John

Learn John’s areas of practice.

John Trebon earned double degrees from the University of Arizona, first graduating with a degree in Business Economics and second as a Juris Doctorate from law school. Since then, he has practiced law full-time in Arizona.

During law school, Mr. Trebon spent a semester in the South (GA & Ala.) working with the Southern Property Law Center and the Law Students Civil Rights Research Council fighting the unjust imposition of the death penalty. Since then, Mr. Trebon has continued to fight the death penalty, serving for more than a decade on the Board of the Arizona Capital Representation Project. He has successfully pursued a federal habeas corpus action to free an inmate from death row by overturning his conviction and successfully avoided the death penalty in another case after his client was convicted of capital murder at trial with a different lawyer.

Mr. Trebon now serves on the Board of the Arizona Innocence Project and has acted as a lead, volunteer lawyer for the Innocence Project in cases filed in Court. One of our cases is now pending before the Arizona Court of Appeals, which attacks the used of “junk science” in court.

Mr. Trebon’s background and professional endeavors supports his mission statement and goal of vigorously representing clients to achieve justice by placing his clients first.

The best
The best and most honest attorney I have ever come across. John is very analytical and understands the law completely! His integrity is unmatched and everyone in the community respects him. When dealing with the opposing side, they generally realize that John looks for the facts and points out how they will decide the case. I would highly recommend John

Highly recommend
I highly recommend John Trebon! He’s a great lawyer, has a wonderful office assistants who are well knowledge in the court system and if they don’t have the answers, they will find the answers. After finding out what I was charged with, I knew I was going to lose everything I worked so hard for but once I called John. Without hesitation, he took my case, defended me in court and to me I say he won! So John, thank you so much, you and your team are amazing!

Misdemeanor charges
John has been amazing since the day we met him. He was able to get 2 misdemeanor charges against my husband dropped completely. The price for his services was fair. We feel fortunate that he was recommended to us.

In trouble? You need John.
One felony charge, two misdemeanor charges dismissed! John is a seasoned criminal law attorney. He is creative, available, open to discussion, has a fire in his belly to defend his clients and will go toe-to-toe with a prosecutor. If you are in trouble – John is who you need.

Laser focus on what matters.
I faced a highly motivated prosecution. John has a laser focus on the elements that matter. His extensive case law knowledge, courtroom instincts, and strategic finesse all combined to deliver a big win today in a challenging case. John knows his stuff. Both he and his staff genuinely cared about me. In the end he wrecked the case against me and left the judge with no choice but to acquit. Score another one for John.

Outstanding and Professional
Attorney John Trebon handled our needs in a highly effective manner. His communication was great as to where our case was headed. The communication aspect was particularly important as we live in Virginia. His staff/ assistant was pleasant and easy to work with. You cannot go wrong with this team in your corner. A winner!

John Trebon represented me in a "freedom of speech" criminal charge. Due to his knowledge of the law and ability as an attorney the charges were dismissed with prejudice. I'm thankful he was available.

Best decision I ever made
I knew after my accident ( I was run over crossing the street) that my injuries and dealing with the insurance companies were more than I could handle. John came to my home and proceeded to take charge of dealing with the insurance companies. We kept in constant contact throughout my ordeal. When all the settlements came in I know that I received double or triple more than I would have working with the insurance company on my own. I never realized how much paperwork is involved and knowledge of the law is required in obtaining a fair settlement. John and his staff were a pleasure to work with. I highly recommend John Trebon.

Brilliant Attorney
Mr. Trebon helped me tremendously with my personal injury case. I was riding a bike when I got hit by a car by someone who had borrowed their roommate's car without consent. Between three insurance companies and a prolonged recovery process, John knew exactly what to do and gave me invaluable advice to help me through the process. I would recommend Mr. Trebon to anyone I know. He is attentive, understanding, and brilliant.

I would never hire anyone eles
Mr. Trebon ended two years of legal abuse in two months. Two other lawyers in town billed me to death but never stopped the problem. I would never use another attorney. Mr. Trebon does fight for your rights and he's quick and to the point.
