School History

St. Isidore school, located in the gorgeous San Ramon Valley, opened its doors to the public in September of 1962. The school staff along with four sisters from St. Francis of Philadelphia served students in grades 1-8, the first class graduating in 1967. The school was thriving and in need of a Kindergarten Program which was added to the campus in 1982.  A few years later a new lobby was built, along with additional resource rooms and classrooms.

Our community of inspired students, committed teachers, and dedicated parents continued to grow, resulting in an increase in the student body. In 1997 the school began offering two classes per grade level, making it the largest Catholic School in the East Bay.  That year a state of the art Technology Center and Science Lab were also added. The gorgeous Rose Sandoval Library was completed between the years of 2011-2012 and quickly became a favorite among students. 

Exciting changes continue to happen on campus including the introduction of the TK program in 2016, Jr. High Math Classroom in 2017 and a major classroom remodel in 2018. The remodel included floors, cabinets, paint, lighting and raised ceilings.  The school and parish continue to oversee numerous construction and maintenance projects including the installation of a security gate at the office and Kids Konnection entrances. SIS is committed to providing students with an engaging learning environment with 21st-century technology. 

St. Isidore School was granted Blue Ribbon Status in 1994 and continues to hold WCEA and WASC accreditation.
