Our teachers support the unfolding individuality of each child as they guide them through their early years of understanding themselves and each other. The wealth of training, experience, and dedication they bring to our nests every day defines the Mountain School and the unique experience we offer.

Celeste grew up in a large family in the Midwest, obtaining degrees in Political Science from Indiana University and Waldorf teacher training from the San Francisco Extension of Rudolf Steiner College.  She believes that the young child seeks kind, joyful, and wise adults that can help them become who they were born to be, and that Waldorf education gives teachers the tools to help this happen.  Celeste began her teaching career by starting a preschool in her home, following the Waldorf early childhood curriculum. She has substitute taught at The Mountain School since 2010, serving in all teaching aspects at the school. She’s also taught at Marin Waldorf (where her three children attended K-8) in sub and volunteer capacities in both early childhood and grade classrooms and at The Hummingbirds’ Collaborative School.
