Teachers are the heart of our community. As mentors they mirror and model the core values of our school by showing curiosity, critical thinking, intentionality, open dialogue and good humor.  Our teachers seek to recognize and honor the gifts each student brings to the table, as they strive to challenge them to new levels of mastery, and guide them in their journey to be engaged learners, self-advocates, and stewards of their natural environment.



Wendy Xa

Founding Head of School

Neuroscientist. Nature Enthusiast. Quadrilingual. Mom.


After founding Presidio Knolls, the award-winning private Mandarin-immersion school in San Francisco, Wendy had a vision for a pioneering school that could combine language immersion, nature-based education, and social-emotional learning into a unified program. With three years of operation under its belt, Terra Marin is the exemplification of this vision.


“I created my first school, Presidio Knolls, to be the school I wanted for my own two children. It was incredible to watch it become everything I dreamed of. Then, over ten years working with hundreds of students and teachers, I learned how to create something even better. That’s what Terra Marin is.”
