Saint Mark’s is a school uniquely designed to honor childhood.

Intentional Space for Learning

Our campus, located in the heart of tree-filled Altadena, is on a scale that is welcoming and inspiring for children. Many of our classes are conducted outside or in labs, where students can develop their intellectual curiosity by exploring, learning, and playing in a dynamic, hands-on setting.


Our school’s focus on these younger years provides the best foundational education possible. With a low student-to-teacher ratio, the relationships between students, faculty, staff, and families help create a vibrant home for learning and growth. As students transition into the upper elementary years, our curriculum and culture solidify their self-confidence before they head into adolescence. Our school prides itself on shepherding students through every step of these formative years of childhood, positioning students well as they transition to the next stage in their education and beyond.


Over the last decade, we have built special outdoor classroom spaces to help bring the curriculum outside. Daily, our teachers and students use these areas to engage with what they are learning through exploration, discovery, and play. Schedule a one-on-one tour with our Director of Enrollment Management to see our beautiful campus.
