A key part of the American women’s soccer team, Mia Hamm and her team achieved victory at the 1996 and 2004 Olympics. She started the Mia Hamm Foundation, which focuses on two missions. The first is to provide support for bone marrow transplant patients and their families. This mission hits home for Hamm, who lost her brother Garrett in 1997 to complications resulting from aplastic anemia. At the 2001 Garrett Game — the all-star game her foundation runs to raise awareness and funds for bone marrow disease research — Hamm reunited bone marrow donors with their recipients. It was a moment she describes as her most satisfying off the field. The foundation’s second goal is the development of programs and initiatives for young women in sports, which of course needs no backstory.
