Cornerstone of Southern California

1950 East 17th Street, Suite 150, Santa Ana, California, 92705
Cornerstone has chosen to adopt Relapse Prevention as it's primary focus, because of the high rate of relapse following traditional treatment. Cornerstone believes chemical dependency is a disease that is chronic, progressive, treatable but not curable. It is a disease that can be placed in remission but is also prone to relapse. We believe both the disease and its Relapse are best treated through physical stabilization, psychological education, self-confrontation and social rehabilitation. We believe those seeking treatment are not guilty for having their disease but are responsible for its management. We believe abstinence is the beginning of the recovery process. Full recovery is total lifestyle change. We believe relapse is a Process not an event. A process that can be Identified, Interrupted and Managed. Cornerstone offers quality treatment programs at reasonable rates in Southern California . We accept most Insurance.

Facility Highlights

  • Tradition of Excellence
  • Individualized Treatment Planning
  • Quality Care


  • Aftercare Support

    Addiction recovery does not end with discharge after completing a rehab program. Facilities that offer aftercare planning and/or support work with patients to ensure sustainable recovery by helping to plan and make arrangements for transitional or sober living, help with housing, vocational counseling, etc.
  • Family Program

    Research shows that the odds of successful, sustained recovery from addiction are far higher when family members and loved ones are involved in treatment. Drug and alcohol addiction often have genetic roots, whether related to substance abuse, mental illness or both. Family dynamics also play a role and, often, family members are the first to realize a loved one has developed an addiction. Also, it’s important for family members to understand and embrace the lifestyle changes that are required to sustain recovery.

Cornerstone is a shining example of recovery excellence. In an industry wrought with corruption and often dubious motives, Cornerstone stands as a model 2 emulate. Keep in mind you will have to buy into and adhere to the philosophy of Alcoholics Anonymous. But that's pretty much every Treatment Center in the United States of America. There are many notable & reputable doctors and scholars that don't buy into AA, but you won't hear them mentioned at a US-based treatment facility. In any case if you find yourself on this page best of luck to you or your loved one in sobriety.
    After the many conversations I've had with their staff trying to accommodate my loved one into their program, they are EXTREMELY rude and only care about money. They seem so bothered when I ask questions like I'm supposed to know all about rehab or something. Pathetic.
    Official Facility Response:

    Your experience was unfortunate and unusual. There is no date provided in your review but hopefully you did get help for your loved one. Insurance benefits have become very difficult to explain to prospective clients. Often it is impossible to check benefits at the time of crisis on weekends and during non-office hours.

      Apparently right at this very moment Cornerstone has kicked my daughter off of their property and will not release her personal belongings or information so she can complete her treatment elsewhere. Apparently they have decided that with 5 or so days to go they need to extend her treatment . For what purpose? And now they are holding her things hostage. For a facility that supposedly is focuses on healing and betterment I guess it only depends on how many $$$ are involved.
      Official Facility Response:

      20% of all clients are scholar-shipped to some degree if motivated. Clients are asked to leave when they are deemed a danger to the community or severely disruptive and even then we attempt to get the client placed elsewhere in an appropriate program. Personal belongings are made available as soon as possible as are medications once they have been checked by our physicians.

        DO NOT send your loved one here. This place is all about money. They aren't professional and and the staff has NO RESPECT.
