⚾ Welcome to the Green Mountain Junior Baseball Association!

 

Green Mountain Junior Baseball Association (GMJBA) is a nonprofit, volunteer-driven organization that has proudly served the Lakewood/Green Mountain community for over 25 years. Our mission is to provide a fun, safe, and competitive baseball experience for local youth.

We offer baseball programs for players up to 14 years old, catering to all skill levels—from tee ball to teams competing in the Rocky Mountain Junior Baseball League and tournament-only teams. Our goal is to place players on teams that match their skill level, ensuring the best possible experience for every athlete. While team sizes and numbers may vary each season based on registration, we strive to field teams at every age level without limits on the number of teams.

The success of our league is made possible by dedicated volunteers, including our board of directors, coaches, and team parents, who all play a vital role in upholding our mission and values.
