What should a drug rehab program possess?

I'm looking for the tell-tale signs of a good rehab program since my father have decided to have an older brother undergo one. His life got all messed up when he found out that his gf for five years cheated her thrice. I wanna help my brother find a rehab that will take good care of him.

Please help.
