Peggy was born in Escondido, California, and lived on her parents' citrus ranch until she was 17 and came to the Los Angeles area for college. Peggy accepted an honor scholarship to Occidental College, later transferred to the University of California, Los Angeles, and finished up at Wright MacMahon Secretarial School. She worked in the purchasing department of a small defense firm and later became a one-woman office for her former boss in his new company.
Peggy married William E. Bloomfield, and together in 1947 they founded Web Service Co., a coin-operated laundry business. This venture was when automatic washers first appeared, and the business grew rapidly. Peggy was the "office," and her husband managed everything else. They spread out gradually, until the company finally covered all of the Sun Belt across the country. She is still active on the Board of Directors, as Secretary and Chair of stock records. Web Service's national headquarters is located in Redondo Beach.
Peggy has one stepdaughter, Carole, and Bill and she have two children: Joanne Hunter and William Bloomfield, Jr. Together, they have eight grandchildren and six great-grandchildren. Her husband passed away in 2004.
At UCLA, Peggy is active as a member of the Board of Councillors of The UCLA Foundation, Chair of the Chancellor's cabinet of the Chancellor's Associates, a member of Women & Philanthropy, and participates with other groups. She serves on the board of the Westwood Village Rotary Club Auxiliary and the Concern Foundation. Also, Peggy is active in her Bloomfield Family Foundation, plus being a supporter of the Jonsson Cancer Center at UCLA, KCET, the Music Center, and Childrens Hospital Los Angeles. She is a member of the Mayflower Society and the D.A.R, as well.
