About Our Recovery Centers

About Cornerstone Healing Center

Established in 2017 in Scottsdale, Arizona, Cornerstone Healing Center’s substance abuse treatment programs were inspired by Estil Wallace, who, after his journey to recovery, was compelled to provide a platform for others to experience the same transformative healing that reshaped his life. With an intuitive understanding of addiction and the essentials for lasting recovery, Estil created a dedicated team that has grown remarkably from its modest origins.

At Cornerstone, we underline the importance of:

  • Authentic human connection: We believe meaningful relationships are crucial for successful recovery.
  • Character development and integrity: We foster a nurturing environment for our clients to grow and evolve, emphasizing the value of honesty and strong moral principles.
  • The willingness to change and heal: We encourage our clients to embrace change as the first step towards their healing journey.
  • Accountability: We promote responsibility for one’s actions, as it empowers individuals during their recovery.
  • Learning to embrace challenges: We instill resilience in our clients, teaching them the value of perseverance and growth from adversity.
  • Giving back to the community: We advocate the practice of altruism, encouraging our clients to contribute positively to society as part of their recovery process.

Our Vision

Our Vision is to create a safe environment for healing and long term recovery from drug addiction and alcoholism. Through passion, structure, soul-searching, and fun; we seek to change lives from the inside out.

Our Mission

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 happen rapidly.

This facility is different from any other rehab that I have been to. I have had many failed attempts at getting and staying sober since I was 16. Mostly due to a majority of the treatment centers that I had went to not having much help with aftercare. They would get you clean for however long the stay was and then release you with no tools or foundation to build on. Cornerstone immersed me in the 12 step recovery program. The PHP groups were extremely therapeutic for me. They took me to Recovery meetings every day of the week. They have extremely nice houses to go back to while you’re not at the clinic. Most importantly, they set me up with an aftercare plan that put me on a path to success. Before I left they made sure that I was set up with a sober living, a job, and also made sure that I had made good progress in my 12 steps. After I got out I was sent to IOP, and every week they have a navigator who makes sure that you are doing well and helps you with any obstacles you may be facing. All of the staff truly cares about every individual who comes through this place. Unlike a lot of treatment centers, cornerstone is not in it for the money. Thanks to them I have been able to maintain long term sobriety. I am the happiest I have been in my entire life. I will forever have gratitude for cornerstone and to all of the staff that helped me, and continues to help on my recovery journey.

I watched my loved one struggle with an addiction to alcohol for over fifteen years. In 2022 he was at the worse I had ever seen. I suggested a multitude of things to quit, however, I knew that he needed help and was convinced that this was not going to end well. I had seen the program of recovery outlined at Cornerstone and convinced my loved one to make the 1,800-mile drive across the country. It saved his life. I hardly recognize this man today. From hustling me to pay for "just one more night" at a hotel, to having his own apartment in a year is a miracle. Cornerstone provided him a safe place and provided every tool possible including inpatient treatment, A.A., therapy and counseling, IOP and helped with his transition into the mainstream of life. I’ll be forever grateful.

this place saved my life 100%. the whole staff genuinely cared about me and were only trying to help me grow. i have confidence again and goals to achieve. coming from someone who was very suicidal and a bad alcoholic before treatment, i’ve completely done a 180°. i loved my house managers lacey and jazz who were both extremely important to my recovery. my primary therapist Lori was such a sweetheart and i could tell she genuinely cared about my life and wanted to help in any way she could. i feel like i’ve finally found my place in this world and most importantly myself and that’s all thanks to God and Cornerstone.
