ABC Preschool & Daycare at 20135 San Miguel Ave in Castro Valley is a historic, family-owned center established in 1963—the first preschool in the area—with CCLD license #015700561 and capacity for 21 children ages 2–5. The center's Montessori-inspired, child-centered curriculum emphasizes practical life, sensorial exploration, and early literacy through active learning, complemented by a Soccer Shots enrichment program. With flexible scheduling (full-time, part-time, after-care, drop-in), included meals, bilingual Spanish-speaking teachers, and extended hours 7:00 AM–6:00 PM Monday–Friday, it serves working families well. Its 4.5-star Yelp rating from 43 reviews reflects strong community trust; parents should note that the center carries 4 Type B citations on its CCLD record—within typical range for an established center—and the small licensed capacity of 21 may result in waitlists for desirable enrollment slots.
