Miller is a partner in a limited partnership which purchased Silverado Country Club in Napa, California on July 1, 2010. He also owns a golf design company and a golf academy and designed the Thanksgiving Point Golf Course in Lehi, Utah, host of the Champion's Challenge. Although Miller has helped design 34 golf courses, Silverado was the first course he redesigned himself. In July 2013 it was announced that Silverado would again play host for a PGA tournament starting in October 2014, when it hosted the Frys.com Open. The renovation added over 300 yards, removed trees and repositioned bunkers. Miller served as the unofficial face of the resort during the event, as he was a part of the telecast, which frequently referenced his role in the club. When he had to fulfill official club duties during the week, Miller's friend and NBC colleague Roger Maltbie filled in for him.
