The Arc of Tri-Cities vision is to empower everyone with Intellectual and Developmental Disabilities (I/DD) to make informed choices. Thereby they will become independent, productive people fully integrated in their communities and in the fabric of society. Through programs, services and supports, persons with Intellectual and Developmental Disabilities will be viewed as people first to achieve their full human potential.

"Disability is a natural part of the human experience and in no way diminishes the right of individuals to live independently, enjoy self-determination, make choices, contribute to society, pursue meaningful careers, enjoy full inclusion and integration in the economic, political, social, cultural, and educational mainstream of American society."
