Our Purpose

Our Purpose

Cornerstone Care Centers Incorporated’s primary purpose is to provide sober living homes and housing assistance grants to recovering alcoholics and addicts. Cornerstone Care Centers also aims to educate those in early stage recovery about longer-term recovery living alternatives. Many addicts struggle with the challenge of staying sober in the days following a release from a treatment center or hospital, and Cornerstone aims to mitigate this by providing immediate housing assistance.
It is Cornerstone’s intent that no one is denied the opportunity to succeed in the quest for sobriety. It is also crucial that families are educated and understand the processes involved in obtaining sobriety.

Who We Can Help:

There are a number of circumstances in which sober housing may a helpful solution. All that is required is an established commitment to remain substance-free and live a sober life.
Cornerstone can assist the following individuals:
  • Recovering addicts and alcoholics
  • Those at risk of institutional placement
  • Persons transitioning from institutional settings
  • The homeless
  • Entrepreneurs looking for guidance on how to start their own sober living environment
  • And more



Newly sober men and women are extremely vulnerable to relapse. While a sober living environment (SLE) cannot diminish the risk of relapse entirely, a supportive and substance-free environment can lower it, oftentimes significantly so. Research has shown that a recovering addict has a far greater chance of remaining substance free if he or she lives with others who have also embraced a sober lifestyle.
We believe—and research has shown—that safe, stable, sober living environments are an essential part of a successful, long-term sobriety.

The free services we offer, include:

Help finding adequate housing

We can help people locate sober living homes that provide interim support and services for those wanting to live a sober lifestyle and who are potentially at risk of institutional placement, those transitioning from institutional settings, those who are homeless, and especially any person struggling with drug or alcohol addiction.

A variety of housing options

Sober living environments can be offered in apartments or homes, or in congregate settings that may be larger than residences typically found in the community.

Long-term, community residences

We can help people locate long-term housing in stable, supportive community living. The variety of community residences we refer people to are safe, affordable, accessible and stable and will help foster sobriety and recovery.

Short-term housing

We can help those who have recently left the prison system, a rehabilitation or mental health facility and are in need of temporary, month-to-month housing.


Financial assistance

For those who are eligible, we offer financial assistance in order to offset the costs of an SLE residency. Some of the ways we can help lower expenses include: grants, sliding scale fees and donor beds.



We offer educational information to those struggling with drug or alcohol addiction and their families.

Sober living homes can help those in recovery in ways that are real and measurable. As research has shown, sober living environments (SLEs) work. Several studies have found SLEs to be a key component of a successful and long-term recovery.
If you would like to make a donation to a cause where your efforts will directly impact those suffering from the mental illness of addiction, call 855-287-8763 or click the “donate” button to be redirected to our PayPal page.

100 percent of all the donations received go directly towards funding someone’s stay in a sober living home.

Cornerstone’s generous board members have agreed to personally fund all overhead expenses, including any staff salaries. This is done in order to show donors that we are sincere about our mission to help others and so that donors may rest assured that 100 percent of their gifts will be used to help those who need it most: The men and women in the US and around the world who are in desperate need of a safe and sober place to live.
