The Otto Armleder Memorial Education Center is located in downtown Cincinnati.

The school was founded in large part by Cincinnati businessman Carl Lindner, Jr., in 1989 on a 25-acre (100,000 m2) plot of land.

The construction of the Edyth B. Lindner Elementary School adjacent to the original campus building took place in 1992.

It is home to CHCA's Upper School students in the ninth through twelfth grades.
