Kellan Tilton is a 6-year-old cancer survivor who is king of the mountain with the help of his wheelchair skis, known as a monoski, to go out on diamond trails. He balances and turns while being tethered to someone else who makes sure he doesn't crash. Kellan was born with neuroblastoma, and paralyzed from the waist down. It only strengthened his zest for life. In addition to skiing, he rock climbs and serves as an ambassador for the St. Baldrick's Foundation. InsideEdition.com's Lisa Voyticki has more.
