Hi Barbus,
We are from the Greater Cleveland Area too. I agree that you should check out Menlo Park. I took a tour there a few months ago and they seem really good.
My daughter is starting Kindergarten next month. Currently we are going to try our local public school, but we are keeping Menlo Park in mind if it doesn't work out. Though, it will also be a long drive for us.
I too would love to hear any other suggestions.
Also, I have been thinking for a while now about setting up a Meetup group for parents of gifted children. I would love to meet other parents in the area.
