Thank you to everyone who has supported the CLS Boosters this year. As a community, we were able to give back 10% more for next school year. We are working on some unique initiatives to rollout for the 2026-2027 school year, and can’t wait to share it with you! We couldn’t do this without you.

We are excited to announce the Booster Board for 2026-2027. We are already working on new things for the school year!
