GT Dave, founder and CEO of GT’s Living Foods, is widely credited with bringing kombucha into the mainstream U.S. market. Starting in the mid-1990s from his family’s kitchen in Los Angeles, he transformed a homemade health drink into a billion-dollar brand, now the leading kombucha company in the world. Known as the “King of Kombucha,” Dave built his business without outside investors, maintaining full ownership while expanding into wellness beverages that emphasize authenticity, probiotics, and natural ingredients. His story reflects both entrepreneurial persistence and a passion for health-driven innovation.

Geoffrey H. Palmer, founder of G.H. Palmer Associates, is one of Los Angeles’s largest apartment developers, with more than 13,000 units across the metro. He stamped downtown with Italianate mega-complexes like the Medici, Orsini, Piero, Da Vinci, and Lorenzo, and reshaped policy with the 2009 appellate win Palmer v. City of Los Angeles, which limited rental inclusionary mandates under California’s Costa-Hawkins Act. A prolific Republican donor, he remains a powerful—if polarizing—force in L.A. real estate.
