Is There a Drug and Alcohol Rehab in Brooklyn, New York?

My colleague Dave approached me yesterday to tell me about his secret: he is addicted to alcohol and drugs. I was surprised about what he said and I asked him why he decided to tell me about it. He told me that he needs my help. He asked me if I know a drug and alcohol rehab somewhere in Brooklyn. He said that he finally gathered the courage to admit his problems and he asked me to accompany him to a rehab. I think he’s doing the right thing and I’m very proud of him. Please help us find a rehab in Brooklyn. Thanks.
