Sign Language Services International, Inc. (SLSI) began as Sign Language Services in 1987 to provide quality and dependable Sign Language interpreting to the Baton Rouge community. At that time, the staff had combined experience of over forty years in a variety of capacities: interpreter, educator, advocate, program administrator, Sign Language instructor, interpreter educator, lecturer, consultant, community leader, and parent. Since 1987, services have expanded to meet the changing demands of a vibrant Deaf Community.

This expansion now includes the Baton Rouge region, the state, the national, and the international levels.  Interpreting services have been provided for international conferences within the United States and overseas.  SLSI has consulted with government agencies (United States and abroad) to provide expertise in the development of testing of Sign Language and interpreting abilities for state and national certification.  A 24-lesson Sign Language course was developed to allow for a self-paced introduction to American Sign Language for those who might be interested in learning America's 3rd most common language.

SLSI is an Associate Member of the European Forum for Sign Language Interpreters.  SLSI is also helping to provide infrastructure development for the World Association of Sign Language Interpreters in conjunction with the Registry of Interpreters for the Deaf, Inc., representatives from 11 countries, the European Forum of Sign Language Interpreters, and the World Federation of the Deaf.
