The Summit Country Day School is a private, Catholic, co-ed school in Cincinnati. Its Montessori preschool celebrated its 50th anniversary in 2013 and is one of a few schools in Greater Cincinnati to offer academic instruction to children as young as age two. Founded in 1890 by the Sisters of Notre Dame de Namur, the school is now operated by an independent board of trustees. Originally only a school for girls, it has expanded over the years to include boys' enrollment and an athletic program.
