Meet the Team

Paolo Diaz- Club Director

Paolo grew up in Aurora, Colorado after his family moved from the Philippines when he was just five. As a chubby boy with cowlick, Paolo didn't even know what lacrosse was and only became involved after going to some professional games and more so when his son started playing for the Commerce City Tigers, which played through CARA. Even before Bison Lacrosse Club was formed, Paolo's love for the game grew where his goal was to grow the sport in Commerce City, as there were no clubs in the northeast metro area. Paolo's goal is to provide kids and the community at-large with the opportunity to learn, play, and love the game of lacrosse.
