I was sentenced to spend 6 months at Cornerstone from 2/2018-8/2018 and have remained clean since. During my time there, Dr. Stephanie Herring provided invaluable support during one of the hardest times of my life. I greatly appreciate the support I experienced during my time at Cornerstone. I was given the opportunity to figure out how recovery works for me and am happy with my life.

Cornerstone was there for me at one of the lowest points in my life. I had been flown suddenly to California by a rehab called Sobertech. I didn't find out until arriving in Laguna Beach that they told me false info. I was lucky enough to find a hospital to stay at where I heard about cornerstone. It was an amazing part of my life. I cherish those memories. And while life hasnt been easy I'm still off Dope to this day. I'd love to give back somehow. They really cared. And it was a blessing I found them. Forever grateful to cornerstone and all the amazing folks I met employees and patients alike. 🙏

Maria, Diane, Dr Herring, Ashley, and all the nurses are top notch. I couldn’t be happier with everyone and everything here. My experience has been absolutely life changing. Love everyone here. 10 stars if I could and if u waste your time going anywhere else you’re a fool.

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.

We are so happy to hear that Doctor Herring has returned to Cornerstone. Our attorney referred us to her 13 years ago. We are eternally grateful for her and Cornerstone and their Alternative sentencing program.
She was there for us in our scariest moments and stood by our family through it all! She was truly a guardian angel and has helped thousands of people and their families.
Dr. Herring continues to stay in contact with us and shows us nothing but genuine love and support! We LOVE her and are so grateful for her support through all the court proceedings and her heart and compassion. She has become part of our family!❤️
We’d recommend Cornerstone to anyone that needs substance abuse and mental health treatment who have legal charges.

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.

Staff members are super nice and friendly. Dr. Stone does his best to keep you comfortable thru detox. Highly recommend this place. I called 4th of July and left a message, they text me back right away that same day.

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.

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.
