On November 1, 1915, this first state-accredited high school in Santa Rosa County opened its doors for students. It was organized and financed under the leadership of County Supt John T. Diamond of Jay. Professor A.D. Keen, a graduate of Emory University, administered the school program along with a self-trained faculty. This institution was known as the Santa Rosa County High School, as it was then the county's only high school. As other communities in the county soon added grades or built new high schools, the school in Milton became known as Milton High School.
