High School Faculty

At Sacramento Waldorf High School, education always takes place within the context of relationship, whether it is in the classroom, in the lab, on the playing field, on the working farm, in the studio, on stage, or in any of our many campus venues. The smaller size of our school allows students to develop meaningful relationships with both peers and teachers.  Young people are challenged to consider the ethical components of their studies in life and in our school community.

Andrew May

What Andrew loves most about teaching is how organically learning grows and develops throughout life when guided with intention and meaning. A Humanities teacher in grades 9-12, Andrew enjoys teaching at a Waldorf school because he is able to continuously learn and grow through his work with students and colleagues. “Early in my life, I realized how amazingly transformative and exciting it can be to help someone learn something they did not previously know. To this day, that feeling remains central in my work to help others become who they are meant to be.”

Andrew holds a BA and single-subject teaching credential in English Education from California State University, Sacramento. Andrew is currently an MEd candidate in Antioch University New England's transdisciplinary healing education program.

He obtained a Waldorf High School Teaching Certificate from Rudolf Steiner College. As a student teacher at a Waldorf-methods high school, Andrew fell in love with Waldorf education and decided to become a Waldorf teacher.

Before joining Sacramento Waldorf School, Andrew taught Humanities at Waldorf School of the Peninsula in the Bay Area. In addition to teaching high school, he has taught English as a Foreign Language to adults in Busan, South Korea.

A Citrus Heights resident, Andrew lives with his family and enjoys reading, writing, cooking, hiking, and being run ragged by his young children.

She loves teaching from the phenomena, which awakens and nurtures curiosity, while the curriculum strengthens developing intellects and social consciousness. She says, “Waldorf students are not afraid to care. Young adults are far more capable than they give themselves credit for. They deserve to be challenged by teachers who care about them as individuals, and who are passionate about their subjects.”

Currently, Christine teaches algebra 2, biology, speech and debate, and healthy cooking in the high school. She holds a BS in Botany from University of California, Davis, an MS in Plant Pathology from University of Georgia, and a PhD in Mycology from Virginia Tech.
