Adult Clinical Services are comprised of four disciplines-psychology, social work, speech, and nursing-whose primary objective is to work in partnership with consumers and families to enable individuals with disabilities to live and participate in the community according to their personal goals, preferences, and needs. Social workers strive to meet the challenges of mental retardation and developmental disabilities by offering supports and solutions to the obstacles and challenges that face consumers affected by disabilities and their families. They work toward empowering consumers and families to make informed choices, to help create their own lives, and to help determine their own futures. Speech clinicians facilitate the use of a functional, appropriate communication system to allow each consumer to effectively communicate his or her thoughts, wants, and needs. By providing services to consumers within the environment and focusing on interventions that are relevant to each individual's needs, they can better facilitate the use of meaningful communication skills. Psychologists operate on the premise that most behaviors are purposeful and serve a particular function for each individual and positive interventions are more likely to enhance each individual's quality of life and produce behavior change.
