Cornerstone of Southern California, Celebrating 40 Years
Call (714) 547-5375

A Partial Hospitalization Program (PHP) is a type of treatment model that provides a thorough level of care to individuals suffering from mental, behavioral, and substance use disorders without requiring complete hospitalization or staying at a treatment facility. For drug recovery, this can be an important part of a person’s transition back to a healthy, happy, and sober life. 

Transitioning back to a healthy, sober life is just that – a transition. Cornerstone’s PHP is designed to support this transition by focusing on a patient’s independence while still providing structure in their recovery and we do this by offering partial hospitalization. Throughout the day, group and individual therapy sessions are available, however, a greater emphasis is placed on creating new and better coping strategies and a support system or strategy outside of the direct treatment setting.

Is PHP right for me?

Because Cornerstone believes in working with patients to develop a plan that best suits them and their needs, this question can’t be answered with a simple yes or no. Instead, Cornerstone uses the free initial assessment to map out a treatment plan that may or may not include a stint with PHP. Further, as drug rehab progresses, there might be times where the Partial Hospitalization Program makes more sense than others so we work directly with patients to answer this question on an ongoing basis. 

Therapy group listens attentively as young woman shares

Many of our patients live in and around Orange County so that they can participate in PHP while being in familiar surroundings and closer to home and work. Being close to and working with your active support network of loved ones can be a tremendous benefit for patients. Add to that the many enriching non-drug-related activities available in Southern California and attending PHP near you can make a lot of sense for those seeking recovery.

I came to Cornerstone in 1999 overwhelmed and angry. My health was fragile due to my alcohol and drug use and I had legal troubles because of drugs.I wound up in Cornerstone’s Alternative Sentencing Program. I had two Case Managers while I was there: Robert M and Crystal O. They did their job quite differently and yet both were powerfully effective.Fast forward twenty-five years: I continue the sobriety Cornerstone gave me through the strong boundaries and support of their program and staff. I also now work ‘in the field’ of addiction recovery as an author and communicator.As a professional, I enthusiastically recommend all of Cornerstone’s programs, with special mention of the integrity of their Alternative Sentencing Program headed by Dr. Stephanie Herring; a renowned leader in this life-saving work.David Zailer — Author of OUR JOURNEY HOME, WHEN LOST MEN COME HOME, and DEATH OF A FISHERMAN.

My experience at Cornerstone was amazing. I was committed to changing myself, and they gave me all the tools I needed to do it. You will meet with the Lead Doctor and the Head Nurse, and they will help you get through those first few days of detox. I really needed them. The entire staff is very professional and kind (Maria💚). The facilities are spotless and the food is really good. You will spend time in groups getting to know people who are going through exactly what you are.They really sincerely care about you.And if you’re serious about getting your life changed, I recommend Cornerstone.Tim O’Flaherty

Saved me by pulling me out of the cycle. I was in a very very bad place. They Uber’d me about 60 miles and I’m now 6 days from 90. I’m so much happier now. Dr stone and his staff truly care. I thank God everyday for this organization. If you can’t stop, are alone, feel like no one loves you; call them please. After hours calls will forward to someone who will help. They answer their messages too. That’s how I did it at 0330 hrs.

1228 days clean from Painkillers thanks to cornerstone. I left another rehab facility after 28 days with little to no knowledge of PAWS. I soon relapsed. I stayed at cornerstone for a month and did 3 more months outpatient meetings. They kept me on the medication needed to stay off pills and I was able to see my therapist Dr Tanagho (which I still do to this day). When I felt strong enough to come off Suboxone I got put on Sublocade injections and have felt no withdrawals. Raul helped me get on disability the whole 4 months and i didn’t have to worry about paying bills. I was able to focus on taking back control of my life.The Food was awesome. I was able to quit my job that was driving me nuts and finally follow my dream of coaching full time in the sport I love. I have no doubt Cornerstone saved my life, I have no doubt I’d be dead if it wasn’t for them. Thanks to Titus, Maria, Diane, my counselor Raul, Jennifer at intake, all the drivers whose name I forgot. God bless you all, 1228 days straight and I’m not looking back. I can’t recommended this place anymore, if your sick of it all and ready to move on, Go to Cornerstone.

My experience here at Corner Stone has honestly been great. I’ve been to one other treatment center, but nothing compares to the focus and determination that these counselors and people put into us. I’m very fortunate to have come through this program and met the people that I have met.My suggestion for anybody that is planning on coming here is to do this for yourself and not no one else because when you fix whatever you have going on mentally or emotionally and get the tools that will help you succeed in turbulent times you will be successful not only one day at a time But you will also have a beautiful journey up ahead.-Difficult roads lead to beautiful beginnings-

My experience at CornerStone has been really great. Not only all the staff members like Emily, a BCH TECH, or my case manager Maria Carter who really cares, I’ve met some very Ginuwine people who are serious about helping you regain control over your life and away from drugs and alcohol.

I received “outstanding” treatment during my time at Cornerstone Rehab. The knowledge and coping skills I have gained will definitely keep me on track throughout my sobriety. The staff from the Rehab Techs, Nurses, Case Manager(Maria Carter), Drivers and my House Manager all the way to the management team were always very professional and willing to assist with all of my needs.

I am extremely grateful to the entire staff at Cornerstone. Case managers are always available to listen, and help you adapt. The doctors and nurses are very precise and safe at every stage of recovery. The techs and site managers are always available to make you comfortable and to answer questions.I came in very uncomfortable, as expected. But I had all of my questions answered, given the tour, shown the schedule, and introduced to people and other elements, in line with my comfort level.Aside from the staff, they allow you to live with and establish co-dependency with other patients. Some with very similar problems, and some with a different set. Group sessions, activities, and living together all come down to one commonality though – finding the path and the strength to recovery.A very special shout to Case Manager, Maria Carter too – I have never known anyone who exudes hope and positive energy like her. She listens to you, and hears you. Truly dedicated to making us successful.

I am so grateful for Cornerstone. since entering this program I have been gifted hope back into my life. I have gained the courage to enroll in school, the opportunity to rebuild family relationships, and build a sober network and life! this program supported me in a way that made restarting in a new state possible. I have been in treatment many times before here, but gained new insight and tools past my previous knowledge. I love that the transition has been smooth from PHP all the way to sober living. My therapist was absolutely amazing and my case management team was incredible as well!

Cornerstone has been such a blessing in my life. Out of all the treatment centers I could’ve gone to, I’m so fortunate I landed here. The staff was helpful, and friendly. It felt as if they knew from experience what I was going through. My case manager Diane, was instrumental in helping rebuild my life and getting me out onto the road of recovery. I absolutely love my sober life today and I can’t imagine I would be here without Cornerstone!

It was literally the turning point in my life. Staff were incredible and the curriculum was just what the doctor ordered. I’m so grateful for Cornerstone. Just celebrated my 1st year of sobriety last December and I would definitely recommend Cornerstone to anyone who truly has a desire to solve the drink or drug problem.Shan Mir

How long does a PHP last?

The length of time a person spends engaged with a PHP varies greatly. At Cornerstone, we believe wholeheartedly that recovery is neither a race nor a competition. Rushing any stage of the treatment process can cause a relapse. With this in mind, the length of stay each person requires within our PHP is completely dependent on the needs of the individual. Our day care program runs seven days a week, but your personalized treatment plan will determine the number of days in the week that you need to attend. The aim is to maintain abstinence, build strength, and provide you with the tools that will propel you into a life free of drugs and alcohol.

What’s PHP like? What can I expect from treatment?

Our comprehensive recovery program with leading addiction professionals will begin at 8:30 a.m. every day. Some of what you can expect is listed below:

  • Group Therapy:  Delivered by qualified addiction professionals these groups are designed to develop the essential skills needed for maintaining abstinence. Focusing on subjects such as relapse prevention, stress management, life skills, coping skills, and addiction education you are encouraged to listen, participate, and learn.
  • Individual therapy:  You will meet regularly with an assigned addictions therapist. Here you work intensively to further explore addiction and maintain abstinence.
  • Medical assistance: A medical team is available to treat and care for you. Many clients still suffer from physical complications due to their substance abuse and require medical oversight during withdrawal and detox. Your comfort is important to us and we are confident in addressing any medical needs that arise.
  • Planning for Aftercare: We encourage a client-led aftercare plan; together we begin to build the future. This can include things like our sober living homes right here in Southern California or participating in our alumni programs.  Meeting your needs individually by making sure all bases are covered and having a solid aftercare plan in place can be the difference between life and death.
  • Holistic Approach: Cornerstone’s holistic approach to addiction includes activities and sessions such as yoga, meditation and mindfulness, music, and art therapy along with a wide range of social activities. Used in conjunction with traditional treatment modalities, we are able to deliver a rounded and balanced program.

Days at Cornerstone PHP usually end mid-afternoon. Groups can be emotional as well as informative so time for reflection is advised. Make the most of your recovery community at Cornerstone by planning an activity for the evenings, whether that be attending a meeting or having fun; the free time granted by a PHP is best used constructively.

Am I Allowed to go Home at Night?

Yes, but we have noticed that many clients find home life challenging, especially in early recovery. The chaos that addiction causes can make returning home difficult. Cornerstone provides Licensed Recovery Homes; these are safe and sober environments that are perfectly situated for those engaging in our Partial Hospitalization Program. Remember – stable and supportive housing is vital in recovery.
