Our vision is to be a centralized resource for quality communication access among Deaf, Deaf-Blind, hard of hearing, and hearing people. We aim to be responsive to the dynamic communication needs and preferences of the communities we serve. We also strive to support the continued growth of interpreting practitioners and to assert a positive influence on the advancement of the profession of sign language interpreting.
