ISSAC teachers are life-long learners who bring culturally rich backgrounds, professionally diverse experiences, and complementary talents to the team.

Our teachers are committed to ISSAC team-teaching methodology by working continuously together to fine-tune lesson plans and regroup students for differentiated learning. So while a teacher may lead a homeroom or subject matter, the role changes periodically. An ISSAC student is a student of all ISSAC teachers.

As the pandemic hit, Shainna started mixed aged nature learning pods at the forests, parks, and beaches along the San Mateo coast, with her daughter as one of her new students. Along with Waldorf and Gymboree trained teachers, the children learned about the ecology of the area, sang songs, constructed crafts, played cooperative and inventive games, climbed trees and were engineers at the beach. At the same time, Shainna tutored First Grade homeschoolers at family homes. She organized fieldtrips, scheduled guest speakers, and helped build a strong community.

Oceania Class

Ms. Susie

I began my teaching journey 25 years ago as a graduate teaching assistant at Cal State University Los Angeles. While there, I learned and practiced the ideas and philosophies of Paulo Freire and bell hooks. Those are still remarkable, creative, and transformative ideas that I strive to apply in my classroom. After finishing my MA in Language Arts; Communication Studies, I earned my CLAD Credential, and began teaching in K-12 schools. I worked with students of multiple ages, abilities, cross cultural, and socio-economic backgrounds.

When my four children were very young, I became interested in language development and began instructing EFL and ESL students from all over the world. These experiences gave me a varied spectrum of students and cultures, and have informed my instruction to allow for and adapt to various learning styles, cultural strengths, and the various individual talents in our learning environment. My own learning continues as I take Art courses and enjoy reading great books. In my spare time I love to go hiking, swimming, and take in live performances. I believe each student has a story, a hope for a future, and a reason to be exactly where they are. It is my desire to facilitate learning in such a way that the journey to your goals is affirming, insightful, and produces quality results. I am eager to work with you in safe, encouraging, and challenging ways forward.
