OCS St. Catherine of Siena Preschool is a Catholic faith-based center at 335 North Sycamore Avenue in central Rialto, operating as a CCLD-licensed Day Care Center for over 25 years. The affiliated parish provides stable institutional backing and serves preschool and Pre-K ages (3–5) with a curriculum spanning religious education, language arts, math, science, and arts. Small capacity of 35 children allows intimate class sizes, and both full-day and half-day schedules accommodate working families. The center is private-pay only and does not participate in subsidized programs; prospective families should review CCLD inspection records before enrolling, as both Type A and Type B citations are on file.
