Sky Siljeg
When his brother bought him a skateboard for Christmas in 1999, Siljeg, then just five years old, vowed he'd practice every day until he turned pro. It didn't take long. The Bothell, Washington–based wunderkind won his first competition less than a year later and scored a sponsorship with Jones Soda. Competing against pros twice his age, he finished 29th in the 2006 World Cup Pro Bowl North American rankings. Now 13, Siljeg has a license to distribute his Sky skate brand worldwide and serves as a consultant for Scholastic.com. "I don't think of skateboarding as a sport," he says. "It's more like art to me. It will be the same trick, but everyone has their own style."
