The HEC is located at 7300 State Road, Parma, OH.
It is NOT at UH Parma Hospital. Do NOT go to the hospital!!!!
The HEC is a former elementary school building, and is set off a bit from State Road, but there is a big UH sign where you turn in. There is plenty of free parking. Click on the link below to see a map.
Basically, from I-77, (either north or south) you take Exit 153, Pleasant Valley Road, and head east towards Independence for about three and a half miles. Turn right onto State Road, go only 0.2 miles, then a left into the road leading to the HEC.
