Cornerstone, located in Greenwood, South Carolina, is an outpatient-based provider offering an Intensive Outpatient Program (IOP) for adults working through substance use or co-occurring concerns. It is one of just three facilities in the local area offering IOP-level care and one of three offering services in Spanish, making it accessible to a broader range of individuals and families. The program includes care for opioid use and chronic pain, a combination shared by only a handful of nearby providers.

Cornerstone works with couples navigating recovery together and uses motivational interviewing as part of its therapeutic approach. Ambetter insurance has been reported as accepted, and financing or payment plans are available for those managing treatment costs. Together, these features describe a community-based outpatient option for people seeking flexible, language-inclusive care close to home.
