Since 1956, Happy Hollow School has provided pre-school through kindergarten care for the Metrowest community. Located just around the corner from the Fuller and McCarthy schools, the school stresses development through self-confidence, creativity, and physical activity. One of the school's core philosophies is "learning through play." The school offers full- and half-day preschool and pre-K, full-day kindergarten, and after school programs that run until 6pm.
