About us

The Cornerstone Mission

Cornerstone was founded in 2017 in Scottsdale, Arizona by Estil Wallace. After changing his life through recovery, Estil felt a great calling to bring healing and transformation to those struggling with addiction as he did. Estil understood the formula to a successful long-term recovery. A team was assembled and has since grown exponentially from its humble beginnings. 

We emphasize: 

  • Human connection
  • The development of character and integrity
  • The willingness to change and therefore heal
  • Embracing accountability 
  • Learning to take the hard way 
  • Giving back

The Cornerstone pHILOSOPHY

Cornerstone’s philosophy is simple. Addiction thrives in isolation, and the antidote to isolation is true and real human connection. Our Scottsdale rehab facilities are where true healing, connection, and transformation can occur. It’s where those who were once broken by addiction can become alive again. 

We believe in helping people broken by addiction to heal mind, body and spirit. By overlapping science with spirituality, we create an environment where a seemingly miraculous healing event sufficient to bring about recovery can and does happen rapidly. 

We know the way out of addiction
