Bill McCarthy began his production career in 1969. After attending the Woodstock Festival, he returned to his hometown in Rhode Island and produced his first special event, entitled the "Sunfeast Celebration." The event was attended by 10,000 people and generated front page news.

In the 1970s, Bill moved to San Francisco and began working in the non-profit production field. In 1975 he initiated and co-produced the San Francisco Unity Fair. The event brought together 45 organizations and 40,000 to 50,000 people. The highlight of the event was a Reunion Concert featuring the Grateful Dead and the Jefferson Starship. Building on the success of the Unity Fair, Mr. McCarthy founded the Unity Foundation in 1976, with the mission of promoting world peace, cooperation and unity.

Since that time, he has produced, organized, or managed major events in San Francisco, Los Angeles, New York City, Washington DC and Las Vegas. The events have featured some of the most prominent people in the music, film and television industries including: Stevie Wonder, Carlos Santana, Bonnie Raitt, Melissa Etheridge, the Grateful Dead, Herbie Hancock, John Lee Hooker, Alanis Morisette, Michael Bolton, Jerry Seinfeld, Martin Sheen, Danny Glover, Patti Duke, Woody Harrelson, Edward James Olmos, LeVar Burton, Katey Sagal and many others.

For more than two decades, Bill McCarthy has worked to promote the work of the United Nations - by producing television documentaries, public service announcements, UN Charter Day Celebrations and United Nations Association Film Festivals.

Since 1998 Mr. McCarthy has produced the "Positive Spin" television program, which presents positive, innovative and solution oriented news. The program airs on cable stations in Northern and Southern California; and nationally on Free Speech TV on the DISH Satellite Network.
