Delta Zeta’s national philanthropy, supported by both collegiate and alumnae chapters, is speech and hearing and The Painted Turtle camp. Delta Zeta's partnerships with and The Painted Turtle
and The Starkey Hearing Foundation
were announced at the 2006 National Convention. All of these important programs provide additional volunteer and giving opportunities for collegiate and alumnae members.
Chapters also support local and national speech and hearing organizations, such as Gallaudet University in Washington, D.C., the only four-year liberal arts school in the world devoted wholly to the needs, instruction, and training of young people who are deaf, and the House Ear Institute, which is one of the world's foremost research, teaching, and treatment centers in the field of hearing.
