About Greenbriar Treatment Center
Greenbriar Treatment Center is a long-standing Western Pennsylvania substance use treatment program located at 800 Manor Drive in Washington, PA. The center is now part of GRC Advanced Recovery Network, the same organization that operates Gateway Rehab — a consolidation that means clients moving through Greenbriar have access to the broader GRC continuum of care and clinical resources across the network.
Clinically, Greenbriar offers a complete continuum: medical detox for clients in active withdrawal, residential treatment for those who need 24-hour structure during the early phase of recovery, and outpatient care for step-down support and longer-term maintenance. The program is accredited by the Joint Commission (JCAHO) and uses evidence-based approaches including cognitive behavioral therapy, individual counseling, and group counseling. Treatment serves men and women with substance use disorders and co-occurring conditions, including clients arriving through the court system.
Greenbriar’s Washington, PA location sits in a campus-style setting on Manor Drive, designed to give clients enough separation from day-to-day triggers without isolating them from the support of family during treatment. Within the GRC network, the campus is one of several touch points clients may use as they progress from detox through residential and into outpatient care.
Payment options reflect the broad network reach: Medicaid, private insurance, TRICARE, state insurance plans, and self-pay are all accepted. For admissions, the main line is 724-378-4461; the GRC central line is also accessible at 1-800-637-4673. Prospective clients and families can also visit gatewayrehab.org for current intake information across the GRC network.
