In 1982 the two schools merged, creating the only Catholic, independent, coeducational college-preparatory school in the region. The Glen Oak School building became the Gilmour Academy Lower School in 1986.
Gilmour Academy has changed over the years, from the creation of its Middle School in 1974 to the continual addition of new facilities. But it has never strayed from the teaching of Holy Cross founder Blessed Fr. Basil Moreau, C.S.C., “We shall always place education side by side with instruction; the mind will not be cultivated at the expense of the heart.”
