How will I find treatment centers in Corsicana, Texas, that deal with dual diagnosis cases?

My neighbor is an alcoholic, and he happens to be depressive as well. He's asking for my help in finding a treatment center for him. He has helped me out a lot of times when I needed help with something. I don't want to let him down now. So if anyone out there has any suggestions, please share them. Thanks.
