Jon R. Sanner


I believe that preparation is the key to success, not only in litigation, but in life. I have recently become an avid runner and I have learned that training hard for a race is the key to realizing your goal. The same holds true for litigation and trial work. If you put in the time and effort in preparing a case for trial, success will follow. I pride myself on putting in the effort to obtain the best possible result for my clients.”
