"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."
