An intervener is a person who regularly works one-to-one with an individual who is deaf-blind. Deafblindness is a low incidence disability that describes individuals with varying degrees of vision and hearing losses. The combined loss often compromises the ability to access information in the environment or to communicate effectively. Interveners, by contributing communication and information, provide a medium through which deaf-blind individuals can link to the people, things and events in the world. Interveners provide services in educational settings for students, as well as in early intervention and community settings. The improvement of the social and emotional well-being of individuals with disabilities, is the goal of interveners.
