Our School Leadership

Wendy Xa
Founding Head of School
Neuroscientist. Nature Enthusiast. Quadrilingual. Mom.
Wendy envisioned a model that blends language immersion, nature-based learning, and social-emotional growth.
At Terra, this vision thrives through a trilingual (Spanish and Mandarin immersion), project-based, nonprofit forest school rooted in the IB framework. With a focus on rigorous academics, global awareness, and flexible band scheduling by skill level, Wendy’s approach ensures every student is challenged, supported, and prepared to become a compassionate global citizen.

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.
