I Have a Loved One Ready to Get Help With His Addiction.?

I am located in the North East and need advice on an interventionist, a drug rehab and alcohol treatment center. I am not sure where to start. Any help on treating someone with an addiction problem would be appreciated. Thanks!
I should add that I am in the North East US. In Mass.
I have found the help I need. It took me a minute… The phone number listed below was posted incorrectly. I found them at 800-762-5433. And you were right. They were wonderful. Everything is set up. My SO will be entering treatment some time next week. Thank you!!!
