Founded in 1850, San Domenico School is the longest-standing independent school in California and a vibrant, forward-thinking community serving students from kindergarten through 12th grade. Rooted in the core values of Study, Reflection, Community, and Service, we prepare students not only for academic success, but for lives of purpose, integrity, and impact.
Our K-12 structure offers a seamless educational journey that nurtures intellectual curiosity and personal growth at every stage. Younger students benefit from role models and mentorship from older peers, while older students develop leadership skills and a deep connection to community. This continuity fosters a sense of belonging and stability, ensuring students are known, supported, and challenged as they grow.
San Domenico embraces international diversity, welcoming students from across the globe in our vibrant high school boarding program. Our diverse perspectives enrich classroom discussions, foster empathy, and prepare graduates for leadership in an interconnected world. No matter where our students call home, SD offers a supportive, college-preparatory environment where learning continues beyond the classroom through shared experiences and cultural exchange.
Set on a breathtaking 515-acre campus in Marin County, our school offers unparalleled opportunities for learning and exploration. From creek-side science experiments to mountain-top hikes, the natural environment inspires focus, creativity, and environmental stewardship. State-of-the-art facilities support innovation in academics, arts, and athletics, while expansive open spaces encourage play, movement, and reflection.
Excellence with purpose is our hallmark, combining rigorous academics with a commitment to kindness, ethical decision-making, and service. Students are empowered to think critically, collaborate effectively, and lead with compassion. Our graduates leave with the confidence and skills to thrive at top colleges and to contribute meaningfully to an ever-changing world.
At San Domenico, education is more than preparation for the next step; it is preparation for a life well-lived.
