Glenmont's first school opened in 1926. Built at a cost of $50,000, the Glenmont School had 136 students enrolled in its first school year. Miss Ruth Burroughs was the first principal. The Glenmont School was located at 12210 Georgia Avenue (then called Brookeville Turnpike), on the site of land to which the Glenmont Fire Station relocated to in 2016. The brick schoolhouse had four classrooms, two special department rooms, and an auditorium. It was built after the consolidation and closure of schools in Aspen Hill, Layhill, and Wheaton. The Glenmont School served students who lived in Glenmont, Aspen Hill, Layhill, and Wheaton. The Cissel-Saxon Post of the American Legion donated an American flag to the Glenmont School in 1928. Major E. Brooke Lee donated a memorial flag pole, which was dedicated in the memory of Paul Latene Hull, who was killed in action in France during World War I.
