OLG Crest
Who we are

A school built on grace.

Our Lady of Grace is a Catholic, language-enriched school in Castro Valley, serving children from Junior K through 8th grade. Small enough to know every child by name, ambitious enough to teach them in more than one language, and rooted enough to build them on grace.

We are the only Catholic dual-language school in the Diocese of Oakland. Families do not just enroll here. They belong here.

Built on

Unity. Truth.
Love.

The three words already in our crest, and the principles the school was founded on. Augustinian to the core, lived every day.

Unity

One community, every child known by name

Small classes, families who know each other, two heritages meeting at one table. No one belongs alone.

Truth

Our academic promise

We name each child's God-given gifts, teach with rigor, and let real effort come to light. Dual-language thinking, classical roots, real science and arts.

Love

The gospel, lived

Faith woven through the day, not bolted on. Daily prayer, sacramental life, service, and the love of Christ shaping how everyone shows up.
