Meet Our Team

Our Team



We’ve assembled a highly-credentialed team of doctors, therapists, and specialists. They have collectively worked with thousands of clients throughout their careers in helping adolescents and young adults struggling with drug and alcohol abuse and/or mental health issues like depression, and anxiety.

We firmly believe a highly experienced, dedicated team with a passion for working with teens and young adults is the single most important piece of a program. Our team is fully committed to our mission of relentlessly pursuing successful clinical outcomes.
