Faculty & Staff

Our high school students are confident, critical thinkers who meet the world with curiosity and a sense of purpose. When asked why they feel prepared for life beyond high school, students will often answer “their teachers.” Each faculty member is a specialist in their field, and most have advanced degrees along with years of training and experience in Waldorf education. All are deeply committed to student success.
