Supermodel and philanthropist Petra Nemcova founded her charity, Happy Hearts Fund, in 2006 with a mission to rebuild safe, resilient schools in areas impacted by natural disasters. Since its inception, she has been involved on a daily basis. Her initial work in an executive capacity has helped establish the structure, vision and strategy that positioned HHF for long-term success. She has led HHF to benefit more than 50,000 children and 500,000 community members thus far. Happy Hearts Fund & All Hands have now merged to form the organization All Hands and Hearts - Smart Reponse. Nemcova swings by BUILD to discuss the new organization's goals.
