Varsity Head Coach-Nathan Jerome
After over 20 seasons of coaching all ages and levels of basketball I am excited to serve as the leader of the Chargers program. The '24-'25 season was my first at Chatfield. The three previous seasons (2021-2024) I served as the varsity assistant at Dakota Ridge High School. In those three years we only lost one league game, won the 5a Jeffco league twice, won the team sportsmanship award, played twice in the Coliseum for the Elite Eight and had a player that was voted 5a Jeffco MVP and second team all-state. When I am not coaching I serve as the director of a local private family foundation. My wife Vali and I have four teenage children.
