Meet the Faculty
2021-2022
Committed to a humanistic approach, our high school teachers encourage their students to be creative, self-disciplined, and independent intellectuals capable of high academic achievement and personal growth. Faculty share and model lifetime learning by developing new classes and working with students on a range of activities — from debate to Bollywood — outside of class.

I was drawn to education because I enjoy sharing my love of finding things out.” Greg’s sons are part of the Waverly community – Kazuo ’21 and Eiji in 11th grade. (Email)

Jennifer Johnson
Jennifer is the learning specialist for kindergarten through 12th grade. Jennifer has a California Teaching Credential, a Master’s in teaching, and certification as an educational therapist. Led to a career in education by a lifelong fascination with the many different ways people think and learn, Jennifer is happiest when around children and teens and believes that most kids are naturally curious and seek challenges to stretch themselves. To support them, she explains,“Often, you just need to give them the time and space to follow their curiosity. For children who may find themselves facing tasks which are too challenging, what is often needed is support in building the skills to feel capable of meeting a challenge.” (Email)
