The mission of the Mental Illness Developmental Disabilities Coordinating Center of Excellence is to make life better for people with dual diagnoses of mental illness and a developmental disability. We help create access to expert assessments and recommendations. We train and educate people to provide services that address their needs in both areas. We support mental health and developmental disability systems to get to know each other, talk to each and improve how they work together. We help communities build their knowledge and resources for serving this population.
