Zach was born with cerebral palsy and discovered snowboarding through the sports program at the Children's Hospital in Denver. Daniel Gale recruited Zach to join his snowboard team at age 13 and helped him progress into an elite athlete. Miller credits him as the most influential person in his athletic career as he has taught him not only how to be an athlete, but to be an ambassador. 

While working with Gale and Adaptive Action Sports, Zach quickly moved through the international rankings and earned a spot on the U.S. Para Snowboard team in 2018. He has since become a two-time World Champion, 5-time World Championship medalist, and Paralympian (2022).  Zach’s goal is to “be a guy you always want out on the hill with you. Maybe [to win] a Paralympic gold medal too.” His favorite sports memory is winning his second World Championship title with Mike Minor. Recently, Zach Miller was awarded the 2023 “Best Athlete with a Disability” ESPY. Zach wrapped up last season with three medals at the 2023 World Championships in La Molina in banked slalom team (gold), dual banked slalom (silver), and snowboardcross (bronze). 

Zach describes himself as a massive nerd, a huge gamer, and extremely competitive; his favorite thing about snowboarding is how fast he can go. His hobbies include gaming, riding motorcycles, and clay target shooting. Additionally, he now works as a coach at Adaptive Action Sports, teaching new development athletes to snowboard and start racing; he also set up some new PCs in the office so they can start building a local adaptive E-Sports Program.
