Are there substance abuse treatment centers in Ellwood City, Pennsylvania that handle dual diagnosis?

I need to know how I'm going to find treatment centers that are ok with taking in patients that have dual diagnosis. My neighbor has that illness and seeing him struggle with it pains me. Can anyone give me tips on how I'm going to find treatment centers? I would really appreciate it. Thanks.
