OC500 2025: GREG CUSTER 

GREG CUSTER 

EVP  

WHITTIER TRUST 

WHY: Oversees Newport Beach office of West Coast’s oldest and largest family office, a trust that made its money discovering oil in Bakersfield and founding Beverly Hills. Whittier now has 300 outside family clients with $29B in assets. Named 2020 Man of Character by OC Boy Scouts. Boards of OC YMCA and United Way. 

IN THE NEWS: Whittier Trust Newport Beach office often ranked highly on OCBJ’s Best Places to Work for midsize companies. 

NOTABLE: In line to become president of Pasadena Tournament of Roses in 2032. 

QUOTABLE: “The recently passed Big Beautiful Bill is prompting wealthy families to sharpen their financial strategies rather than overhaul them. With expanded estate tax exemptions, revised SALT deductions, and renewed Qualified Opportunity Zone legislation, affluent individuals are recalibrating how they manage wealth across generations.”
