Wendy Xa

Head of School

Two-time school founder. Neuroscientist. Mom.


Terra Marin is Wendy’s “encore project” after founding Presidio Knolls, the award-winning private Mandarin-immersion school in San Francisco.


“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.”
