At the heart of McLean Hospital is a mission to help those impacted by mental health through treatment, research, and public and professional education. In treating conditions such as depression, anxiety, and addiction, our entire organization is dedicated to improving the lives of patients and their families with innovative treatments based on the latest research. Our staff, faculty, students, volunteers, and supporters are helping create the future of mental health research, diagnosis, and treatment based around collaboration and individual care plans that empower patients beyond their treatment.
