Our Promise

How Is Recovery.com Different?

We believe everyone deserves access to accurate, unbiased information about mental health and recovery. That’s why we have a comprehensive set of treatment providers and don't charge for inclusion. Any center that meets our criteria can list for free. We do not and have never accepted fees for referring someone to a particular center. Providers who advertise with us must be verified by our Research Team and we clearly mark their status as advertisers.

Our goal is to help you choose the best path for your recovery. That begins with information you can trust.
