And here's the mission of the ECF generally:
We offer a broad spectrum of programs, a calendar of workshops, support groups, online resources and emergency financial assistance to support the unique, essential needs of all who work in performing arts and entertainment. We assist everyone working in theater, film, television, radio, music, dance, opera and circus, whether on stage or on camera, behind the scenes or below the line. Administered through our offices in New York, Chicago and Los Angeles, these programs help people across the country to solve problems and make positive changes in their lives.
