Before School Care is available on school days from 7:30-8:30 AM. Toddler and Primary students participate in our Early Care Program in the Rainbow Room at the Toddler/Primary building.
Our ELMS students who enroll in before school care will attend our BOKS program, a before school play and physical activity program aimed to give students a boost at the start of their day in the gym. Advanced registration is available by season, as well as drop in if space permits.

Drop ins should be confirmed, and should be arranged via email with as much advance notice as possible. Drop in requests can be email to:
