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 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.
