Erick Harris and this law firm saved my life!!
I had no idea what to expect when my husband of sixteen years told me he wanted a divorce; he left the state with the kids. From the second I called Canon and Associates, I knew that there was no other law firm in Oklahoma I would want to handle my case. Lisa Smith is always there for every question; she always seems to get back right away. She is so caring and empathetic; EVERY law office needs a Lisa. I was assigned Erick Harris, and after googling him, I felt a wave of relief. He is a highly regarded attorney in the state with an impeccable reputation. I was impressed that he knew the judge that we would appear before the trial. Erick and the firm have treated me with respect throughout this process, and despite shooting myself in the foot on numerous occasions, I have never felt embarrassed or judged. Erick continues to fight and has my back on all issues despite being my own worst enemy. When I had a panic attack at the courthouse before the temporary order hearing, Kelly stayed with me on the phone and calmed me down. She contacted Erick and gave me an ETA until he arrived. She was incredibly kind, compassionate, and caring. The day of the hearing was a blur for me; I was in such an emotional state Erick sat with me after the hearing and just listened as I poured my heart out and cried. This man probably had many other things to do, yet he sat there with me. I feel it is essential to have a law firm that views you as a human being and not as a dollar sign. This law firm far exceeded any expectations I had of them. I still have a ways to go in my Divorce journey, but I know I am in the best hands. If you require a law firm and Divorce attorney, this is the law firm with the people you want standing by you!!! Do not hesitate or waste a precious second; call them now. Trust me; it is the best decision you will make in your life.

Mr. Cannon was quick to respond to my request to meet, was professional in every interaction, and most importantly, he used his good professional standing with important contacts to help accelerate my timeline for my specific life needs. While my experience will be impossible to replicate exactly, I can say with confidence that Mr. Cannon will work with you and your needs toward the best possible resolution for you. He will not treat you like just one more client to run through the assembly line. Mr. Cannon has my firm endorsement for those of you looking for professionalism and client care.

One of the Best
When I contacted John Cannon and his firm , I was very skeptical . I needed an attorney. Not just any attorney, but a good attorney because of my past . I came in and met with John and explain to him my situation. I was in the wrong place at the wrong time and with my past , I was very scared about my upcoming battle with the judicial system . John did not judge me or make me feel inferior . He treated me like I was just like any of his other clients. When you have a past , people tend to stereo type you , but he did not . John did not. He wast straight forward. Told me his plan. He made me feel at ease. John is one of the best attorneys I have ever had the privilege to meet .He fought for me and got my case dismissed. If you're looking for an attorney and want somebody that will fight for you and your rights, then you need to call John Cannon. I owe him my life.

Special Thanks To Mr Elliot with the John Cannon Firm
I contacted John Cannons firm seeking legal representation and Mr Douglas Elliott handled my case. I called several different firms prior but after speaking to Mr Elliott I knew I found the right guy. From beginning to end everything went right. I was facing an unjust situation & Mr Elliot fought hard for me & got better results than I had even anticipated. In the courtroom Mr Elliot is witty, quick thinking & spoke well defending my case. He had the stern judge overseeing my case laughing when everyone else was walking on eggshells. I highly recommend Douglas Elliott. He did a great job and was very reasonable on price. No surprises unless they were good surprises. 5 Star rating⭐⭐⭐⭐⭐

John is amazing!
Words cannot express how grateful our family is for making time to advise and represent our son. Our son was a suspect of a crime of which he was falsely accused and was asked to visit with law enforcement. Without John we would not have known how to navigate the process of a law enforcement interview. A very scary thing and something none of us in the family knew how to handle. On short notice (less than 24 hours before the interview) John agreed to meet with our family and attend the interview with our son. In short, the interview was a success and the falsity of the accusations were uncovered. Without John and his advise who knows how the interview would have gone. John is a kind, compassionate, and wise lawyer with a heart for doing the right thing.

I have used Mr. Cannon on 3 separate cases in the past 4 years
Mr. Cannon represented me on a felony, misdemeanor and civil case these past 4 years. He fought for my rights in all 3 cases and I have been very pleased with all of my outcomes. John is very thorough, explanatory, and un biased. He was not judgemental and very supportive. I definitely recommend Mr. Cannon and his law firm.
