In 2002, Dr. Goodstein led the highly successful Deaf Way II conference in Washington, DC., a week-long celebration of Deaf cultures which brought together 10,000 people from around the globe to discuss and celebrate deaf scholars, artists, students, and citizens. In 2004 Gallaudet awarded Dr. Goodstein Professor Emeritus status in recognition of his significant contributions.
