30th Anniversary

CSD (also known as Communication Service for the Deaf, Inc.) opened its doors on Nov. 1, 1975, in Sioux Falls, S.D. The South Dakota state legislature provided funds - matched by the South Dakota Association for the Deaf - to help create CSD.

What began as a one–person venture now covers 27 offices throughout the nation (along with 1,500 employees).

CSD offered services like interpreting and TTY repair in 1975, and today operates the telecommunications relay service for 35 states, along with an array of human services. From serving only Sioux Falls, S.D. in 1975 to the entire nation today, CSD looks forward to serving you.
