Best Corporate Do-Gooder Orange County 2013 - PIMCO
No Orange County billionaire (your Brens, your Argyroses, your Nicholases) made Forbes' most recent list of the 25 billionaires nationwide who have given the most to charity (your Buffetts, your Gateses, your Bloombergs). But one OC billionaire's global investment firm is among the top donors to those in need, and because of its corporate policy to get involved with gift recipients, many of those charities are Orange County-based. Newport Beach's Pacific Investment Management Co. (or, more commonly, PIMCO)—led by co-founder Bill Gross, whose $2.3 billion net worth as of March made him Forbes' 641st richest person in the world and 221st in the U.S.—has a $55 million-strong foundation. The nonprofit supports education, disaster relief and, to spur in-house participation, an "employee choice" selection drawn from nominations by PIMCO staffers. While Gross didn't make the list of top billionaire givers, he's no slouch, having personally given tens of millions to UC Irvine, Hoag Hospital, Duke University and Doctors Without Borders. The $20 million Gross and his wife gave to Cedars-Sinai Medical Center in Los Angeles led to this summer's opening of the Sue and Bill Gross Surgery and Procedure Center.
