Who do the Ultimate Fighting Champions go to when they need to be put back together? They go see Dr. William Kessler, otherwise known as The Fight Doc. A proud graduate of the Los Angeles College of Chiropractic, Dr. Kessler has been practicing in Orange County for the past 16 years. The Fight Doc specializes in the treatment and rehabilitation of sports injuries, and educating athletes in wellness fundamentals. However, he prides himself in his ability to treat patients from all backgrounds, whether they need care for work related injuries, car accidents, or physiological degeneration acquired over time.
