Summer & Fall Teams

We Aim to Educate!

Lacrosse is a fast, physical game that demands players make quick decisions on the fly. We stress creativity and understanding of basic concepts, not uncompromising rules and tactics. We give our players the opportunity to make plays.

COSMO Lacrosse was founded on the principals of fun, long term athletic development, and two dad's wanting to spend time with their kids. Coaches Ben and Drew launched our first "club" team in the summer of 2021. Our combined 2028/2029 team played in two local tournaments and played box lacrosse throughout the winter, spring and summer together. Why? Because sport is meant to be fun and we have loved the game of lacrosse since we played as kids in upstate New York (Syracuse, NY). Now, we look to continue to grow the game of lacrosse and not only teach our kids but to grow the game for boys and girls in northern El Paso county because we love the game.
