"John did a very good job. Although the outcome was not 100% what we expected(strange judgement) it was overall positive. I would, have and will continue to recommended him. Although I certainly hope to not need his services again in the capacity I hired him for I would not hesitate to call if I do. Thanks John"

- MICHAEL RICKARD

"I signed up with John June 25th, July 5th I received an email that my case is in line to be DISMISSED, within a 2 week time period John made what was one of the most stressful times in my life better! Every case is different but he handled my case with care and he was extremely open in his communication throughout the whole process. I hope to never have to have a criminal attorney again but if I do I will definitely go back to John. I highly recommend him to anyone else who is needing an attorney!"

- ASHLEY

"John is a highly respected attorney. Professional and compassionate. He has a wealth of knowledge, being a military officer and having served as an Assistant District Attorney, a Public Defender, and an Assistant Attorney General. He helped a friend's son who was headed down the wrong path, but through John's legal defense the young man is now a successful business owner."

- ATTORNEY COLLEAGUE

"John is a very professional attorney, who is not only concerned about the welfare of his client but very attentive and considerate of the family, or other bodies that are in the face of the adversity. While working on my family members case, John took time out to take a class that would educate him on how to approach the many different types of cases tried in the court room. John proved his sincerity to the calling of his job, being an attorney. I would definitely recommend him to anyone."

"Mr. Cannon went above and beyond for my wife. She was facing some pretty hard fines and prison time with the US Marshalls. Mr. Cannon fought a hard fight and got her a GREAT offer. Words cannot express how much I appreciate him and what he did for my wife. I would give 10 stars and I will be promoting him. He's that awesome. He keeps you informed, he will text or call you back, and he goes above what he is asked to do and I can reassure you"HE WILL FIGHT FOR YOU OR YOUR FAMILY MEMBER". I will continue retaining him for other things my wife is battling. High five and a great big hug to Mr. Cannon. Thank you!!! John took the reigns and provided us instant peace of mind. He was timely, respectful, transparent, very professional, honest and courteous. The service he provided was above and beyond our expectations. Can’t believe professionals like him are around. Highly highly without reservations recommend him and his team."

"John Cannon is an excellent attorney. He takes sincere interest in your needs. He maintains communication and provides all the information you might want to fully understand the legal process. He also suggests alternative resolutions to your legal needs so that you can make informed choices. I definitely recommend John."

- DUDLEY

"My experience with CANNON & ASSOCIATES was absolutely amazing. I hired John Cannon two days before my rebuttal statement was due back to the Staff Judge Advocate. Within that time frame he was able to talk to my Battery and Battalion Commanders, review my evidence, and help me write a rebuttal statement that help prove my case to them, the Brigade Commander and the Post Commanding General. Cannon worked thru the night to help me get the best results for me and my family. Due to his hard work and attention to detail I am still able to continue to serve my country and progress in my military career with no adverse actions on my record. I can not thank him enough on a job well done. Cannon showed me that he was invested in my case and I highly recommend you hire him when you need someone to represent you in a legal matter."

I can't say enough good things about Mr. Cannon. He's incredibly knowledgeable with regards to military justice. The outcome of my case was successful and I attribute that to Mr. Cannon's professionalism and expertise in dealing with military law. I would highly recommend Mr. Cannon to anyone with military justice or criminal defense needs."

I will definitely use Mr. Cannon in the future for any and all of my family's legal matters."
