HSDC’s Interpreting Services Program is a centralized resource for quality communication access among deaf, deaf-blind, hard of hearing, and hearing people in the Seattle area and the rest of Washington State.  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. SignOn Interpreting Services was founded in Seattle in 1997 and became a program of Hearing, Speech & Deaf Center in 2011.  In 2017, ASLIN joined forces with HSDC’s SignOn department and the two became Interpreting Services at HSDC.
