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. As we enter our fifth year in operations, Terra Marin is the exemplification of this vision.

Teachers
 

are at the heart of our program

Teachers are at the heart of our program. With a <1% acceptance rate, we hire only teachers who can create magical learning experiences in the classroom. Our teachers have previous experience teaching in Forest, Montessori, Reggio Emilia, and Language Immersion schools. And small student-teacher ratios (5:1 in preschool through transitional kindergarten, 8:1 in kindergarten through 8th grade) allow our teachers to provide the personalized attention your child needs to thrive.
