The school's 37-acre campus in central Tucson includes a 370-seat theater, science and technology center, basketball and volleyball gymnasium, band room, soccer and baseball/softball fields, a state of the art fabrication lab and a dining hall.

The idea for the Gregory School began with Ruth McCormick "Bazy" Tankersley, an Arabian horse breeder and former publisher of the Washington Times-Herald.

Roger Douglas, then rector of the St. Philip's in the Hills Episcopal Church and a small number of interested friends.

In time, an independent board of trustees was created to establish the school as a 501 c(3) entity, able to receive tax-deductible donations.

Russell W. "Russ" Ingersoll, who had been rector and headmaster at private boarding schools in Virginia and Wisconsin.

In turn, Ingersoll, working out of a rented trailer in the unpaved parking lot of the St. Philips Episcopal Church, carried out a national search for teachers to fill the necessary posts for the school.

By January 1980, he had hired the school's first teachers: Christopher Boyle of Delaware for English, Vinton Geistfeld of Minnesota for math, Oscar Morales of Tucson for languages and Howard Zeskind of Washington, D.C., for history.
