Born in Easton, New Hampshire, to Jo Kenney and Woody Miller, Miller grew up in nearby Franconia, a small community in the heart of New Hampshire's White Mountains that comprises the Cannon Mountain Ski Area.
Miller first gained widespread recognition after winning two silver medals at the 2002 Salt Lake City Winter Olympics in the giant slalom and combined events, though he had been known to skiing fans since he burst onto the international scene as an 18-year-old in 1996.
