Nature's Classroom

What Nature's Classroom does

Nature's Classroom, Inc. is a Massachusetts-based non-profit organization founded in 1973 by Dr. John G. Santos to provide residential environmental education to school groups, primarily serving grades 2-8. The organization operates two interconnected service lines: School Programs, offering 1-5 day immersive outdoor field trips with NGSS-aligned science curriculum, field groups of 12 students, special interest classes, and team-building activities; and Prindle Pond Conference Center, a year-round retreat and event venue hosting weddings, professional development workshops, and family gatherings. The infrastructure spans 600+ acres in Charlton, MA (Hilltop and Pondside facilities, plus the Hemlock Building) and 125+ acres in Swanzey, NH, with combined capacity for up to 300 individuals across dormitory, condo, and cottage-style lodging. There is no proprietary technology platform; the value proposition rests on five decades of curriculum development, on-site trained teaching and medical staff, ServSafe-certified kitchen operations, and a strong referral network among New England school administrators. The go-to-market motion is sales-led, relying on free informational presentations to teachers, parents, and school boards, with schools funding participation through field trip budgets, state STEM initiatives, grants, and donations. The organization is governed by a Board of Trustees and, following the founder's passing in July 2023, continues operations under the leadership of Stefan Sage as President & Treasurer.
