Acadia Healthcare is a United States-based mental health care company headquartered in Franklin, Tennessee, founded in January 2005 to develop and operate a network of behavioral health facilities. The company operates 253 treatment facilities across 39 states and Puerto Rico, offering a range of care for behavioral health and substance use disorders, including detoxification, residential addiction treatment, residential treatment for dual diagnosis, acute psychiatric inpatient hospitalization, medication-assisted treatment, and outpatient programs such as partial hospitalization programs and intensive outpatient programs. Acadia states a mission to provide care in supportive environments that enable patients to regain hope, with a management approach that emphasizes collaboration and flexibility. The organization employs between 1,001 and 5,000 people and has pursued growth through partnerships and new facilities in 2026, including a 144-bed behavioral health hospital in Apopka, Florida opened with Orlando Health, and a joint venture with Methodist Jennie Edmundson Hospital. Acadia went public in 2011, and in May 2026 a Delaware Court of Chancery stayed a shareholder derivative action in light of an agreement in principle to settle related claims involving fiduciary duty and the use of confidential information.
