Evan was born on June 4, 1990, to a pair of highly successful lawyers. His mother, Melissa Thomas, graduated from Harvard Law School and practiced tax law as a partner at a prominent Los Angeles firm before resigning to become a stay-at-home mother when Evan was young. His father, John Spiegel, graduated from Stanford and Yale Law School and became a partner at Munger, Tolles & Olson, an elite firm started by Berkshire Hathaway's Charlie Munger. His clients included Warner Bros. and Sergey Brin. Evan and his two younger sisters, Lauren and Caroline, grew up in Pacific Palisades, an upper-class neighborhood bordering Santa Monica in western Los Angeles. John had the kids volunteer and help build homes in poor areas of Mexico. When Evan was in high school, Melissa and John divorced after nearly twenty years of marriage. Evan chose to live with his father in a four-million-dollar house in Pacific Palisades, just blocks from his childhood home where his mother still lives. John let young Evan decorate the new home with the help of Greg Grande, the set designer from Friends. Evan decked out his room with a custom white leather king-size bed, Venetian plaster, floating bookshelves, two designer desk chairs, custom closets, and, of course, a brand new computer.
