Founded in 1976, Rainbow Montessori began on a small school site in Campbell. Operations expanded over the years to include six more small school sites located across the South Bay Area. In the mid-80's, those seven small schools were consolidated into three larger schools, which were eventually consolidated into the current site, located on the former campus of Sunnyvale High School.

Our current site affords us the space to provide care and education for over 900 children, ranging in age from six weeks to twelve years. The Montessori program is utilized in all preschool, kindergarten, and elementary classrooms.
