Erin enjoys live music, traveling, hiking, and most of all loves spending her free time exploring and playing in nature with her two young boys.

Celebrations and Events

Thorne Nature Preschool values building a strong, supportive, inclusive community between classmates, families, and preschool staff. To this end, Thorne holds family events to celebrate nature and the changing seasons throughout the year. We know that learning doesn’t end when preschool ends and that there is nothing more important than family to a young child. To support nature connection for the entire family, Thorne leads family hikes and nature exploration days, as well as hosts parent education events that include childcare. Thorne believes that a healthy, rich, meaningful sense of community within the Nature Preschool, cultivates the human connection that is equally as important as nature connection.  

See the Nature Preschool Calendar to learn more about our community events and celebrations.
