Potrero Kids (PK) is a year round, Spanish bilingual, dual-campus preschool operated by the Potrero Residents Education Fund (PREFund). Open from 8:00 a.m. to 6:00 p.m. and serving three meals a day, PK provides high quality preschool services to the working families of San Francisco's Potrero Hill and Eastern Neighborhood communities. PK's first campus is a unique concept -- a private bilingual preschool located on a public elementary school campus. Considered a pilot program, the Potrero Kids at Daniel Webster (PKDW) preschool is integral to expanding community support for Daniel Webster Elementary School while also providing a much-needed preschool option in Potrero Hill. In the fall of 2012, PK expanded to include a new campus on Third Street (PK3).
