Mission & Philosophy

“It is the love and affection from teacher to student, and from student to teacher, that endures and continues to live on, long after the school lessons and experiences can barely be recalled.”

Jacque Grillo, June Bulletin

Since 1974, Lone Mountain Children’s Center has welcomed young children and their families into a joyful, nurturing preschool community. We are an independent, non-profit, non-denominational school located in two adjacent historic buildings in San Francisco’s Presidio.

Lone Mountain offers an inspiring environment where thoughtfully designed classrooms and expansive outdoor spaces invite exploration, creativity, and a deep connection to nature.  

Our theme-based curriculum balances independent play and teacher-led activities.  Through emphasis on traditions and daily rhythms, children experience routine that fosters confidence, self-assurance, and a sense of security.  Our long-tenured, deeply devoted teachers build meaningful relationships, nurturing each child’s sense of self while cultivating social-emotional growth, confidence, and a lifelong love of learning.

At Lone Mountain, childhood is honored, community is cherished, and love is at the heart of all we do.
