Greenhouse Treatment Center CEO Anthony Walters

Anthony Walters, CEO

"I believe that we have the ability to make a difference in the lives of individuals temporarily overwhelmed by addiction. That is no small thing. We offer individuals freedom from the chains of addiction. The work we do matters. And there is hope. We see people get better every day. We are in the business of hope and this is tremendously rewarding."

In 2018, Anthony Walters joined Greenhouse Treatment Center as its chief executive officer. Walters brings more than 20 years of experience serving individuals with addiction and mental illness to his position as Greenhouse CEO. As a strong leader in the industry, Walters has helped multiple facilities to not only increase patient satisfaction but also the overall standard of care. Walters is often invited as a keynote speaker for major organizations in the field and serves as a mentor to aspiring CEOs in the industry. Walters strongly believes that addiction treatment works and that there is hope for individuals suffering from addiction and mental illness. Walters encourages his staff to deliver the highest quality of care by providing outcome-oriented, evidence-based treatment that empowers patients to break the chains of addiction and live healthier lives.

Walters is a family man who has four children and has been married for over 20 years. His passion for helping others, along with his dedication and commitment to delivering the highest quality of care in the field, stems from his grandmother. He observed from a very young age that his grandmother was a healer and always tried to extend a helping hand. Witnessing this as a child led Walters to a lifelong career of helping those in need.

Walters was the 2004 winner of the Arkansas Mental Health Institute’s Practitioner of the Year Award and the 2006 recipient of the Jeannie D. Weiss Award for Professional Excellence.
