Sarah Hodder — Program Coordinator

Ms. Hodder handles every aspect of CELF’s Students for a Sustainable Future EXPO, from recruiting exhibitors to organizing volunteers.

When she is not working on the EXPO, she is co-chair of the Chappaqua Central School District Environmental Committee. Ms. Hodder holds a B.A. magna cum laude in English and American Literature and Language, from Harvard University.
“[CELF’s] course was profoundly important to me. I was already committed to teaching kids about the environment, but this course drove my commitment up several notches. As a result of what I learned, I plan to change the focus of my enrichment class… to refocus on systems thinking, and imbuing the kids with an understanding of our ecosystem, and how various human activities affect it.”
