What Sets Us Apart
We are an independent, coed day school for students in Toddler through Grade 8. And we're located at the foot of majestic Mount Tamalpais in Mill Valley, California.
Founded in 1977, we have always been proud to say that we're a different kind of school. One that fosters a genuine passion for learning, kindness, and positive change. Our curriculum is designed to inspire students to embrace challenges, think critically, and become compassionate advocates. And within our inclusive community, every student is seen, heard, and valued.
How do we make this happen? Our answer is two-fold:
A Transdiscplinary Philosophy
We believe the highest form of academic rigor is not remembering more – it's understanding more deeply.
At Marin Horizon, students develop strong foundations within each academic discipline while engaging in a transdisciplinary approach that intentionally connects concepts, skills, and perspectives across subjects.
They learn to think like mathematicians, scientists, historians, writers, and artists, then apply those distinct lenses to authentic questions. Whether studying a watershed, designing an engineering solution, or examining the history of a community, students discover that the world's most meaningful challenges rarely belong to a single subject. They require the ability to transfer knowledge, recognize patterns, and draw connections that deepen understanding and inspire innovation.
A Journey Designed for Becoming
We believe education is not measured in years, but in the journey of becoming.
At Marin Horizon, that journey begins with exploration and unfolds through four intentional chapters - Explore, Discover, Inquire, and Become - each thoughtfully designed to meet children where they are and prepare them for the next chapter.
Woven throughout every chapter are enduring relationships. Students are known not just for a year, but over time, by teachers who understand both who they are and who they are becoming. This sense of knowing and belonging holds true for children who enter at any point of the journey – Toddler, Primary, Lower School, or Middle School. The continuity creates something remarkable: the confidence to take risks, the resilience to learn from failure, and the courage to pursue questions without easy answers.
