We are delighted that you have chosen to consider receiving care at SunCloud Health. We are a recovery-focused therapeutic community. The SC team is comprised of a multidisciplinary team of health care providers who help you develop an individualized treatment plan to reach your goals. Our team consists of psychiatrists, registered dieticians, registered nurses, psychologists, therapists and counselors whose specialties include addiction, eating disorders, mood disorders and trauma recovery. The community at SunCloud includes you, fellow patients seeking greater health themselves and the SC staff. At SCH we focus both on the primary behavioral symptoms interfering with your life, as well as the underlying biological, psychological, social and spiritual factors, including adverse childhood experiences, that interfere with your ability to live a meaningful, joyful and free life. We use evidence-based treatment modalities to execute our mission to provide integrated care to persons with complex, co-occurring conditions who have not been adequately helped by treatment models that focus on one “primary” condition. We use a sophisticated treatment approach addressing multiple co-occurring disorders at the same time, under one roof in an integrated fashion.
