I need to find drug rehabilitation centers in Ephrata, Pennsylvania. How?

I never thought there would come a time when I would be worrying about something like this. You see, ever since my mom and dad separated, my mom has turned into a drug addict. Of all the people who could be addicts, I never thought my mom would be one of them. But now here we are, on this road, wanting so much to do what we can in order for her to revert back to her old self. She has already realized the folly of her actions and is now willing to change. Any suggestions as to how to find drug rehabs?
