A supportive touch

Cornerstone of Southern California is one of the longest running treatment centers in Southern California. Cornerstone was founded in 1984 by current Medical Director Michael Stone, MD. For over 37 years, Cornerstone and its expert staff have been committed to providing the highest level of quality, and ethical care management for individuals suffering from a wide range of Substance Use Disorders and addictions.

Founder and Medical Director, Michael Stone, has been working in the field of addiction and mental health for fifty years. In 1983 he was working in a hospital called Care Unit where people were being discharged early due to insurance companies refusing to pay for further treatment. Michael began to notice that although these people were deemed medically fit and able to leave the hospital, they had not received the level of care necessary in order to maintain long lasting recovery. Many of the discharged patients would return to the hospital after only weeks of having been released, often in a worse state than they had been previously. Realizing that these patients needed a continuum of care once leaving the hospital, Michael decided to set up a sober home to do just that. Thus Cornerstone of Southern California was born.

The first recovery home was designed to help clients abstain from drugs and alcohol while educating them about their disease and the triggers that could lead them back into substance abuse. Since its very inception, Michael realized the importance of relapse prevention and it has been a successful focal point for Cornerstone ever since.

A happy couple celebrating sobriety

Cornerstone is a family run treatment center, which prides itself on its ethical treatment. Being family run, Cornerstone understands how important community, connection and family are, in order to maintain long lasting recovery.

From humble beginnings, Cornerstone has grown from a single residential recovery home into a 20 home system including 4 residential detox homes, extended care, monitored residential and sober living homes. Cornerstone also boasts an outpatient day treatment facility in Santa Ana. As community is vital to recovery, Michael has made sure that all homes and offices are within a 3 mile radius of one another, ensuring that each resident is able to feel connected and part of the Cornerstone community.

It is the truly caring staff that makes Cornerstone the best rehab I have been to. The best part was finally getting my depression medications right, after many others tried for 2 years.
