One of the most coveted party invitations, not just in Houston but also internationally, is from Becca Cason Thrash. You know you’ve arrived when the socialite and fund-raiser for the arts—she’s a board member for the Houston Grand Opera, the Contemporary Arts Museum, and American Friends of the Louvre—asks you to swing by to hobnob with celebrities and check out her gallery-worthy art collection. When she’s not busy entertaining, Thrash finds quiet time at her desk in the library of the 20,000-square-foot manse she shares with her husband, eCorp chairman and CEO John Thrash. Surrounded by paintings, this peaceful spot is where she writes countless letters and thank-you notes to artists, royalty, politicians, and philanthropists.
