Came across this thread. I was at KidScope in 88-89. My understanding is that it wasn't an official branch of KHK, but it was started by KHK people (I'm not sure if that meant staff, graduates, or families). Maybe enough parents got sick of being out of towners and driving to Cinci. I do remember some of the staff 7 stepped from KHK.
I 7 stepped a few months before they closed (but I think there were only six phases). It was in this nasty, run-down strip mall. It was weird--several parents pulled their kids a few weeks before. I showed up for my required monthly Fri. meeting (I was an out of towner) and all the girls were wearing makeup and jewelry. They tried to keep us 7 steppers who were still within the six months to keep having our weekly Sat. meeting. It happened for a couple of months and then fizzled. I wonder whatever happened to our files? I would love to get my hands on mine!
