Can someone tell me how to get contact information of addiction treatment centers in Monahans, Texas?

I want to ask around because I want to know whether any will be willing to take in my friend's son, who happens to have dual diagnosis. I do know that not all addiction treatment centers are adept at handling cases like his, so I really want to make sure before I give my friend some suggestions.
