Skateboarding icon Rob Dyrdek dreams up a series of often eccentric business ventures from a 25,000-square-foot industrial warehouse and an office complex near downtown Los Angeles. Dyrdek began skateboarding at 12, turned pro at 16 and soon after launched his entrepreneurial career that now includes skateboard-related companies, private training facilities for boarders, a skateboarding league and his charitable foundation that builds skate plazas around the country.
