How will I find treatment centers in Moorestown, New Jersey, that also take in patients with dual diagnosis?

I'm doing a project for a class of mine. It's about dual diagnosis and I would like to get more information about it by doing some interviews and I just thought that going to treatment centers will give me more insights.
