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.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.

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
