Graham Memorial Preschool at 380 Orange Avenue in Coronado operates from the Graham Memorial Presbyterian Church campus under California Community Care License #370800236, with a licensed capacity of 70 children in a program that has served Coronado Island families from one of Orange Avenue's most architecturally significant church buildings since the mid-twentieth century. The 380 Orange Avenue address places the preschool directly on Coronado's main commercial corridor, in a James W. Reid–designed sanctuary — the same architect who designed Hotel Del Coronado in 1888 — that gives the preschool a physical setting no purpose-built childcare facility on the island can match. A 1:7 teacher-to-student ratio keeps classrooms at a scale that supports individualized attention for children ages two through five, and the church campus's outdoor courtyard and garden spaces provide shaded play environments within the 92118 village grid. The Orange Avenue location means parents combine drop-off and pickup trips with village errands and commutes, and the preschool sits within walking distance of the Coronado Ferry Landing bayfront, Spreckels Park, the Coronado Public Library, and the residential blocks that house the majority of Coronado's young families. The program's church affiliation provides a faith-integrated early childhood curriculum alongside structured pre-literacy, numeracy, and social-emotional development activities, and the preschool feeds graduates into Village Elementary School on G Avenue, Coronado Baptist Daycare extended-care programs, and other K–5 entry points in the CUSD system. Aquatic safety awareness programming connects families to Crown Cove Aquatic Center on Coronado's bayfront, where age-appropriate swim instruction begins at the preschool level and continues through the competitive aquatics programs that define Coronado Island's water-sport culture. The 92118 ZIP code's walkable village scale means every enrolled family lives within a 10-minute commute of the 380 Orange Avenue campus.
