University of Southern California. His first job after college was as a rotating equipment engineer. He then went back to business school receiving his MBA from the University of Michigan. The next several years were spent rock climbing primarily in California, where he created over 1000 first ascents. Among them are some of the most difficult and dangerous big wall climbs in Yosemite, solo. After formulating the highest friction rubber outsoles, which he called Stealth, Cole founded the Five Ten footwear company originally specializing in rock climbing shoes, then downhill mountain biking, and eventually high risk sports. He holds many patents including a rotating binding called Orbit. After retiring from business, Cole has been pursuing this dark energy/dark matter problem, continuing a lifelong interest in gravity he has had since engineering school. Besides physics, his passions include chess, tennis, and spending time at his ranch.
