Our goal

Our main goal is recovery for each and every patient.

But not only that. All of us – from our program leadership to our staff members – aim to reduce the burden of addiction on our region.

We’re focused not just on providing a service, but on making our community a healthier and safer place to live, work, learn and do business.

Our mission

The mission of Overmountain Recovery is to provide the highest quality of care to those experiencing opioid use disorder, with or without co-occurring disorders, in an environment that preserves and promotes the dignity of the persons served without regard to race, color, creed, gender, economic or social circumstance, sexual orientation, or national origin.


Overmountain regularly measures and reports on the performance of our program. We track both efficiency and effectiveness measures.

Because of this dedication to quality, we’ve earned a three-year accreditation from CARF (the Commission on the Accreditation of Rehabilitation Facilities).

CARF three-year accreditation is the highest accreditation level awarded to organizations like Overmountain.

The CARF accreditation process

To receive three-year accreditation from CARF, organizations are put through a rigorous process that includes, among other requirements, live on-site surveys.

These requirements ensure our programs meet CARF’s high standards of quality and accountability.
