Gisele Bündchen is a busy working mom – but she’s never too busy for family.
So when husband Tom Brady’s sister Nancy Brady asked her to pitch in to raise money for Accordia’s Infectious Diseases Institute, which helps fight disease in Africa, she was happy to oblige.
“Family is very important to me and Nancy’s passion for funding Accordia’s training program after her fellowship in Uganda is inspirational,” says Bündchen. “We are blessed to have families that support each others philanthropic endeavors.”
