Community-Based Care for Every Stage of Recovery
Founded in 1969, Keystone Substance Abuse Services serves as York County’s central resource for treatment, prevention, and recovery. Its main campus, Youth Center, and Prevention Center allow people to access help close to home. As a nonprofit, Keystone provides affordable, evidence-based care through grants, insurance partnerships, and sliding-scale payment plans, ensuring finances never stand in the way of recovery.
Integrated Treatment and Medical Support
Keystone offers 24-hour withdrawal management with nursing and medical supervision to ensure client safety during detoxification. Residential care focuses on women’s recovery, including expectant and postpartum mothers who receive priority admission. The facility also provides outpatient and intensive outpatient programs that combine individual, group, and family therapy with ongoing recovery management. Integrated treatment addresses both substance use and co-occurring mental health conditions to promote lasting stability.
Specialized Programs and Real-World Impact
Programs are designed to meet clients where they are. Gender-responsive services, such as Women of Substance and Men Under Construction, build life skills, address trauma, and strengthen family and work readiness. The Journey program supports young adults through therapy, peer support, and access to medications for addiction treatment (MAT). Keystone also offers DUI/ADSAP, legal, and workplace evaluations to help clients rebuild daily life while progressing in recovery.
Whole-Person Support and Community Connection
Beyond treatment, Keystone helps clients navigate housing, employment, and social services, with transportation assistance and peer mentoring available. Its onsite HIV education and testing program offers rapid testing and prevention education. The facility’s multi-building campus features accessible entrances, indoor lounges, and flexible therapy spaces. Through education, aftercare, and outcome tracking, Keystone continues to evolve its programs, helping individuals and families in Rock Hill find strength, connection, and hope in recovery.

Trust Score
A simple A–E grade that offers a quick view of how much confidence you might place in a facility. It’s not a guarantee of quality or outcomes, but a data-informed tool to help guide your search. More on our methodology.
Commission on Accreditation of Rehabilitation Facilities
CARF reviews rehab programs to make sure they provide respectful, effective, and personalized care. For addiction treatment, CARF uses standards developed with the American Society of Addiction Medicine (ASAM), so this accreditation shows the program follows trusted, evidence-based guidelines for treating substance use.

Across the site, our team has conducted over 1,000 pre-admissions calls to better understand the patient experience, interviewed facility clinical leaders, performed facility background checks, and compared our information against trusted public data sources.
Our research process begins with data from the Substance Abuse and Mental Health Services Administration (SAMHSA), accrediting bodies including The Joint Commission and CARF, government licensing agencies, and other trusted sources. From there, our team conducts significant original research, including:
- Pre-admissions calls: We speak with admissions staff to get a candid picture of patient experience.
- Background checks: We review complaints from past clients, media reports, actions taken by accrediting bodies, and positive recognition from notable organizations.
- Clinical interviews: We have in-depth conversations with clinical leadership, often lasting up to one hour, that give us a better understanding of clinical care.
- Data partnerships: We ingest and analyze exclusive data that provides information about in-network insurance status, cost, and more.
Research varies by facility. Each facility profile shows which research steps we completed and when each step was last performed. Learn more about our research process and background checks.
How we evaluate treatment facilities
These data help us develop a Trust Score for each facility—a simple letter grade that helps you assess how much confidence to place in a facility based on the information available to us. Trust Score considers accreditation, operating history, notable recognition, and concerns identified during our background check. Our Trust Score is an objective rating that is never influenced by advertiser payment. Learn more about our Trust Score methodology.
Important disclaimer
We cannot guarantee the quality of treatment at any facility. We cannot independently confirm the accuracy of every data point, and some information may become outdated or change over time. A Trust Score is a starting point, not a guarantee of treatment quality or outcomes. Please contact us if you would like to update or correct facility information.
