A quiet year for the housing heiress who saw her net worth remain steady. Guerin, 78, inherited most of her wealth from her late father, Nathan Shapell, after he left her a 43% stake in his homebuilding company, Shapell Industries. Founded in 1955, the company’s major developments include Porter Ranch in the San Fernando Valley, East Lake in Yorba Linda and Gale Ranch in San Ramon. Following Shapell’s death in 2007, the company’s home-building division sold to Pennsylvania-based Toll Brothers for $1.6 billion in 2013. Aside from inheritance, Guerin also owns commercial real estate properties. Shapell continues to own and develop retail, office, medical office and multifamily properties. For her part, Guerin built a spec home in Beverly Hills that sold during the height of the Covid-19 pandemic for $23.5 million. Philanthropy: The Cedars-Sinai Guerin Children’s pediatric medicine center opened in 2022, built with a $100 million donation from the Shapell Guerin Family Foundation. Guerin previously served as chair of the Cedars-Sinai Health System board and president of its Women’s Guild. Art: Guerin has produced several theatrical shows including “Leap of Faith” and “Amadeus.” Family: In 2013, the Guerin Family Pavilion opened at the Skirball Cultural Center, a Jewish educational institution in Brentwood. Guerin’s father was a Polish-born survivor of the Holocaust. In 2018, the U.S. Holocaust Memorial Museum honored her parents with a posthumous tribute. She and her husband, Paul Guerin, received the museum’s National Leadership Award.
