I need to find substance abuse treatment centers in Connellsville, Pennsylvania. How?

I especially want to find one that are willing to take on individuals with cases of dual diagnosis. I'm doing a research on the disorder, and I would like to interview some people who are afflicted with it, hence the search for treatment centers that have patients with that illness.
