"I became who I am because my parents volunteered in class."  --Mahatma Gandhi

At St. Isidore School, the parent and school communities work collaboratively to ensure that every student achieves success academically, spiritually, socially, and emotionally. We offer a nurturing environment, helping to prolong the innocence of youth. Parents are encouraged to play an active role in the education of each child by mentoring and volunteering on and off campus through classroom assistance, community building, and fundraising events.

Together we partner to make a difference in our community and beyond, leading efforts to assist those in need of support and generosity. We are truly at our best when helping others. Throughout the year we participate in outreach programs by giving to the Knights of Columbus, Monument Crisis Center, Loaves and Fishes Soup Kitchen, Contra Costa Food Bank, and sister schools in our diocese.

Educating children from Transitional Kindergarten through the eighth grade allows parents and children the opportunity for extended time together, helping to develop strong connections and deep roots. We recently initiated an alumni program that aims to keep students, families, and friends connected and a part of our school community.
