We’re proud to share that our three affiliated practices—Psych Atlanta, Georgia Psychiatry & Sleep, and Roots Behavioral Health—are now part of the Hightop Health family. While each clinic has built its own legacy of trusted care, we’re taking the next step forward—bringing everything together under the Hightop Health name.

This change is part of our commitment to creating a premier, clinician-led outpatient mental health group that sets a new standard for comprehensive, compassionate care. Though the brand is evolving, nothing about your experience is: same expert teams, same innovative treatments, same personalized approach. Now unified by a single mission—to deliver better mental health care that inspires hope and lasting healing.

This transition won’t affect your care—but it will enhance the way we show up, work together, and serve communities across Georgia, Texas, and beyond.
