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.

Since November 1984, 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, mental health disorders, and addictions.

Founder and Medical Director, Michael Stone, has been working in the field of addiction and mental health since 1969. 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.

Dr. Stone 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 a 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 upon leaving the hospital, Dr. Stone 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, Dr. Stone realized the importance of relapse prevention and it has been a successful focal point for Cornerstone ever since.

Our Mission

From detox, to primary rehabilitation, our extended care program and outpatient treatment, we are able to care for our clients until they feel they have all the necessary foundations to fully heal their minds, bodies and spirits.

Our Vision

Rehabilitation should be an enriching experience that fosters personal growth and self-discovery. The process of recovery teaches you new skills to live a joyous, healthy life with clarity about your future goals in mind.

You’re not just a patient at our center, you become part of the family. We work hard to ensure that your aftercare plan is personalized. You can also join us as an alumnus – we’d love nothing more than having you continue your journey with us.

#1 Ongoing Community Support

Our Alumni

The Cornerstone Alumni is a support group for those currently in treatment or who have been recently out of care. 

At Cornerstone, we have witnessed people healing from addictions and families reuniting. Our Alumni program offers ongoing support on a long-term basis by ensuring our graduates don’t fall off the wagon or relapse once they leave campus – but instead, get welcomed with open arms into new life norms that will help them heal in ways only possible through community engagement!

The Cornerstone Alumni are a shining example of how sobriety can be fun, exciting, and worth sharing with others. They attend meetings, activities, or panels to show that they’re still in the game and flourishing in recovery. 

Our Alumni program provides continuing guidance and encouragement to help with your recovery process as you begin building new habits that will sustain long-term sobriety.
#2 Recovery Is A Journey

Our Creed

We’re committed to helping each client feel like the most important person in our lives; because they are. That’s why we treat them with understanding, fairness, and professionalism at all times. 

The residents of Cornerstone never stop working hard on their recovery; as well you know, it takes a village after all… But these people aren’t just statistics or broken automatons – They’re human beings who have feelings and emotions just like you (or maybe even worse than your own).

At Cornerstone, the work we do begins and ends with each client. This means that every single one of us is measured by how well every person is treated; this is what makes or breaks a person in recovery. 

We treat everyone respectfully while also maintaining an air of dignity so as not to underwhelm those who deserve nothing less than excellence from themselves when dealing with the pains of recovery.

Throughout his career, Michael Stone, MD has been involved in treating and helping over 80,000 addicts on their journey to recovery.

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
