Glenview Academy shares a proud history with its sister school, the Gramon School, which was founded by Ruth Newman in her own home in South Orange, New Jersey. Beginning with two pupils, the Gramon School quickly developed a reputation for educational excellence and its enrollment began to increase dramatically. Within a very few years the school had grown so large that it had to be relocated to the South Orange Community Center.
Gramon's reputation and enrollment continued to grow over the years, and in 1994, after three additional moves, the school came to its new quarters, a modern, air-conditioned, one-story facility in Fairfield.
In September 1986, the school was divided into separate elementary and secondary programs, and the elementary program, Glenview Academy, found its first home back in South Orange. The school's early success led to its relocation in two years to a modern facility in Cedar Grove. After an eight-year stint there, Glenview Academy once again came home in 1998 to share the Fairfield facility with Gramon.
