The school was founded by Bessie Henry, an educator from Philadelphia, as a co-ed day school located on what is now the
Colorado College campus at 126 East Cache La Poudre Street, first called Miss Henry's School and later San Luis School. In 1917, the school became an
open air school, holding all of its classes outside. Henry remained the principal through 1921, then Marie Fox Potter became principal (styled as headmistress) in 1922. The school purchased the property at 2555 North Chelton Road, at the base of
Austin Bluffs, and expanded the San Luis Ranch School into an exclusive girls' college preparatory school. In 1942, Mrs. Ena Curry became principal of the school. The school operated at the Chelton Road location until closing in 1951. The former school site on Chelton Road was purchased in 1960 by the
Benedictine Sisters of Mount St. Scholastica Community of Atchison, Kansas and developed into the girls' preparatory school Benet Hill Academy, which operated from 1963 to 1982. The site currently serves as Benet Hill Monastery. ==References==
