Are there any good non-denominational private schools in Cincinnati?

The Seven Hills School is a private school in Cincinnati with no religious affiliation. It's actually the largest, independent private school in Ohio that's not church-affiliated. Seven Hills provides a private education to children all the way from pre-K - 12th grade. (The Seven Hills Upper School is a college prep school as well.) It's overall a very highly ranked institution that offers a great education, but it isn't cheap. Depending on the child's grade level and the family's financial situation, a year will cost anywhere from $5,500 - $19,850.
