Cornerstone of Southern California at a Glance
Cornerstone says it treats all types of substance use disorders. Its site names alcohol, fentanyl, heroin, cocaine, methamphetamine and other amphetamines, prescription drugs, Xanax, cannabis, ketamine, MDMA, kratom, Spice, other stimulants, and newer synthetic substances. Its dual diagnosis and mental health program covers anxiety, depression, PTSD and trauma, ADHD, OCD, and bipolar disorder.
Therapy includes one-on-one sessions, group therapy, family and couples therapy, cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), EMDR for trauma, and relapse prevention therapy. Medication-assisted treatment is offered when it is clinically appropriate. The center says psychiatrists, therapists, and nurses are available around the clock for residential clients.
Residential clients live in homes rather than a hospital unit. The center says residents have their own bedroom, along with catered, balanced meals that can meet dietary needs, plus yoga, meditation, and exercise classes. Photos show a comfortable lobby, living rooms, and a game room with a pool table. Treatment length ranges from about 7 to 90 days based on need, and an extended care program offers more structure for people who need extra time.
Family involvement is a core part of Cornerstone's approach. The center also lists an LGBTQIA2+ support track, an alumni program with a mobile app, aftercare planning, and online treatment. It offers legal support for clients with court cases, including help with alternative sentencing. Incidental medical services (IMS) are available within its residential homes.
All of Cornerstone's homes and offices are in Santa Ana and nearby parts of Orange County. The center serves clients from Irvine, Anaheim, Newport Beach, Huntington Beach, Tustin, and many other nearby cities. This close layout makes it easier for people to step down from residential care to outpatient programs at the same drug and alcohol rehab in Santa Ana.
