Peter Lamdin, Environmental Educator (he/him)

Peter has been involved with the Hitchcock Center, off and on, since 1975 (when it was The Long Plain Nature Center). He helped run summer camp and did school programming, before becoming a classroom teacher at the Fort River School in Amherst in 1980. When Peter retired (or “expired” as one young Fort River student put it) in 2013, he was able to return home to Hitchcock, once again doing programs in elementary schools during the school year, and starting Leadership Training Camp during the summer. Peter continues to work on Leadership Camp, but has re-retired from elementary school programming, and can be found birding, biking, skiing, gardening, playing guitar, and grand parenting when he can, given that his grandchildren live in California. email

During the school year, Jeff teaches our Homeschool II Program, Nature Play Afterschool Program, and classes that visit the Hitchcock Center on field trips.
