KeyStone Center

2001 Providence Avenue, Chester, Pennsylvania, 19013
At the Keystone Center, we acknowledge that the change process is different for every person. One way in which we frame a person’s desire or intention to change is through a model called the Stages-of-Change, which is also known as the Transtheoretical Model. This model suggests that making a difficult change such as stopping the abuse of drugs or alcohol takes place in different stages.

Facility Highlights

  • Experiential Therapy
  • Motivational Interviewing
  • Cognitive Behavioral Therapy


  • Family Program

    Research shows that the odds of successful, sustained recovery from addiction are far higher when family members and loved ones are involved in treatment. Drug and alcohol addiction often have genetic roots, whether related to substance abuse, mental illness or both. Family dynamics also play a role and, often, family members are the first to realize a loved one has developed an addiction. Also, it’s important for family members to understand and embrace the lifestyle changes that are required to sustain recovery.
  • Dual Diagnosis/ Co-Occurring Disorders Treatment

    These two terms describe a person who is not only addicted to drugs or alcohol, but also has a mental or emotional illness, such as depression, anxiety, bipolar disorder, etc. Facilities that treat patients with dual-diagnosis or co-occurring disorders provide psychiatric treatment in addition to drug and alcohol rehabilitation services.

I am currently going through something with a loved one that is admitted here, and let me just say the staff here are VERY unprofessional. I myself was admitted here back in 2015 and they purposely overdosed me and I was in a comma for 3 days. I would NEVER recommend ANYONE to go here.

Keystone was my third treatment center, and just like the addiction gets worse for me so did my rehabs. Keystone is like a zoo most days - locked out of rooms all day, overcrowded, court ordered non enthused patients, rehab romance central. However, bottom line is if you truly want to get sober and change your life, you can do this anywhere. I've been sober since Keystone for 3 and a half years - its not the rehabs fault a person does not stay sober. There are better rehabs, but for me with no insurance and out of options, I'm grateful for Keystone.

My son has been in three detox/rehab facilities in the past year and a half. The KeyStone Center seemed to be the most structured and gave us hope for a positive outcome. Halfway through rehab my son\'s insurance ended and on August 1st he was discharged as fast as they could get the paperwork done. The very next day my son went to the state run offices and immediately got his insurance reinstated. But this was all too late for his rehab. I feel that with all the resources the Center had they didn\'t try hard enough to contact the right office to get my son\'s insurance reinstated while he was still there. What a huge disappointment.
