CLINICAL TEAM

Our ‘Team’ approach means that our Medical, Clinical and Administration Teams work together to provide each patient with what they need. Addiction and mental illness are medical conditions that need to be treated medically and with counseling. It’s this combination of treatment (dual diagnosis) that sets us apart from other treatment facilities.

Each year, Tellurian provides much needed help and assistance to more than 8500 people around the country via treatment and a wide range of support services. Tellurian continues in its mission of optimizing every patient’s chance for recovery by making recovery a reality for all individuals and families seeking help.
