Team

Our People

When asked, “What makes Green Hill special?” our response is always the same: our people. The Green Hill team is composed of experienced clinicians, academics, professionals, and persons in recovery. While we bring a diverse set of skills to help young adults navigate the recovery process, we all share a commitment to our core values and the belief in personal growth.
