Over the past 25 years, Crawley has been at the forefront of the health and fitness industry. His initial work in the field began as a Certified Athletic Trainer at The University of Southern California, his alma mater. While at U.S.C., Dave was a member of the Athletic Medical Staff that cared for athletes on 13 Division I National Championship teams and numerous Olympic medal winners. (Had USC been a country in 1976, they would have come in third in gold medals won at the Montreal Olympic Games.)
