Licensed under California Community Care #376701596 with a 30-child capacity, the Ryan Family YMCA Preschool operates year-round on an August-to-August calendar that aligns with San Diego Unified's school year at 4425 Valeta Street. The preschool sits inside the T. Claude and Gladys B. Ryan Family YMCA campus, giving enrolled children direct access to the facility's pool for six months of weekly swim enrichment and its gymnasium for six months of structured sports programming — an athletics rotation no standalone OB preschool can match. The play-based academic core targets kindergarten readiness through small-group literacy stations, hands-on math manipulatives, and collaborative art projects that develop executive-function skills. Families in OB's early-education network sometimes transition children from smaller home-based centers like Big Dreams Family Daycare to the YMCA program specifically for that expanded physical-development component as pre-K age approaches. The pre-K capstone integrates timed group tasks, early writing conventions, and cooperative problem-solving exercises that mirror a structured kindergarten environment.
