Began shooting at an early age as a hobby before formally practicing with the Bridge Jr. Team under coach In Kim in 2012... While focusing on rehab and therapy in 2017, he practiced shooting as a fun way to focus his mind and pass the time between treatments... He attended his first international match, the 2019 World Shooting Para Sport Championships, where he fired an impressive 564 qualification score in the P3 - Mixed 25m Sport Pistol SH1 event that advanced him into the final top eight... In doing so, Gong earned the United States their first pistol quota spot for the Paralympic Games Tokyo 2020... He credits this match as the moment where all his training and time spent in the sport registered and the Paralympic Games seemed like an attainable goal... Moved to the Olympic & Paralympic Training Center to practice full-time as a resident athlete.
