We provide real treatment for real people. At The Positive Achievement Center at Chapman, we strive to provide patients with compassionate, safe, effective treatment for substance addiction. As a hospital-based treatment center, our patients have access to a supportive community of credentialed medical staff and quality medical care. We believe that high-quality addiction recovery programs should be accessible to everyone. If youâre serious about seeking recovery–not just treatment–we want to help. We accept most major insurances and specialize in treating patients covered by Medicare and Tricare.
