I Need to Find Drug Rehabs in Lewiston, Maine. How Will I Do This?

I have to do this for my brother, who is currently suffering from heroin addiction. Our parents are both away, and I’d hate to give them the news. So now I have to take care of everything, including getting my brother treated. I plan on telling my parents this, but not now. I don’t want them to have to worry. My brother says it’s best not to tell them now too. He says to wait until he’s on the way to recovery. Can anybody tell me how I’m going to find drug rehabs?
