The Team
The people
behind the care.
Credentials that
speak quietly.
Our clinical staff includes board-certified addiction psychiatrists, licensed therapists specializing in trauma and co-occurring disorders, and medical professionals with decades of experience in private care settings.
Staff-to-client ratios are kept deliberately low. You will know your care team by name. They will know yours.
