The organization founded and operated Montessori preschool and elementary classes in rented locations throughout Cleveland.

In 1964, a donation of a classroom building and property on Fairmount Boulevard in Cleveland Heights enabled the east side school to have a permanent location.

In 1977, the east and west side schools separated, each retaining the name Ruffing in honor of Mary and Jim Ruffing, who led the Cleveland Montessori Association in its efforts to introduce Montessori to Northeast Ohio.

With a current enrollment of 326, Ruffing in Cleveland Heights operates from a large, new facility, built according to LEED principles.
