Cornerstone of Southern California, Celebrating 40 Years

Cornerstone of Southern California is one of the longest-running treatment centers in Southern California.

Cornerstone was founded in 1984 by our current Medical Director Michael Stone, MD.

Founder and Medical Director, Michael Stone, has been a pioneer in the field of addiction and mental health since 1969. While working at Care Unit hospital in 1983, he witnessed patients being discharged prematurely due to insurance companies’ refusal to cover further treatment. Despite being deemed medically stable, these patients had not received sufficient care to maintain long-term recovery, often leading to their readmission in worse condition just weeks later.

Recognizing the critical need for a continuum of care post-discharge, Dr. Stone established Cornerstone of Southern California, starting with one sober living home. This first recovery home aimed to help clients maintain abstinence from drugs and alcohol while educating them about their disease and potential relapse triggers. From its inception, Cornerstone has emphasized the importance of relapse prevention, which remains the crux of its successful treatment approach to this day.

I have worked in the addictions field since 1969. Working in drug and alcohol treatment centers and psychiatric hospitals prior to opening Cornerstone, allowed me to see exactly how not to run a treatment center. My biggest motivator for opening Cornerstone was seeing patients in the hospital where I had previously been employed, having to let patients go before I believed they were ready to go. Addiction impacts the mind, body as well as the spirit, so although the body may present itself as physically fit, the mind and spirit will take much longer to heal.” ~ Dr Michael Stone, MD
