Millbrook School is a private, coeducational preparatory boarding school located in Stanford, New York, United States. History Millbrook School was founded in 1931 by Edward Pulling. Pulling was a graduate of both Princeton University and Cambridge University, and he taught at Groton School and Avon Old Farms as well as private schools in the United Kingdom. While at Avon, Pulling began to think of creating his own school. His philosophy for a school was heavily influenced by the traditional setting he experienced at Groton and in the UK, as well as the progressive ideology that Avon possessed. After searching for suitable grounds to house the school — including an offer from then Governor Franklin D. Roosevelt to build in Hyde Park, New York — Pulling and his wife decided on the Stephenson farm just five miles (8 km) outside Millbrook in nearby Stanford, New York. After the purchase of the property, Pulling drafted his first board of trustees, which included Endicott Peabody Sr., who was headmaster at Groton, and Henry Harkness Flagler, who became the first President of the Board of Trustees. With the generous support of the Flagler family and Pulling's father-in-law Russell Leffingwell the campus increased from the original farm buildings to include much of the current campus infrastructure. Environmental Stewardship Environmental Stewardship is one of the five core values of Millbrook School and the school has contributed in many ways with having Trevor Zoo on campus, building solar panels that will source and generate electricity for the entire campus, and building school's architecture with LEED certification. Trevor Zoo Trevor Zoo is the only zoo in the United States that is located inside a high school. The founder of the zoo was Frank Trevor, the first biology teacher at the school. The zoo houses 180 exotic and indigenous animals representing 80 different species, 10 of them endangered. It is accredited by the AZA, the Associations of Zoos and Aquariums. Millbrook students participate with care of the wildlife in the zoo. A curriculum called Zoo community service, mandatory for 9th graders, encourages students to engage in animal husbandry, diet preparation, and veterinary medicine. Notable alumni S.
