About Us


To watch 7-year-old Dorothy McCollum, she certainly doesn't seem halfhearted. But in fact, she was born that way. One of her two ventricles was undersized and ineffective, so her blood was getting very little oxygen. She had, essentially, half a heart. Dorothy was only five days old when surgeons performed the first of three challenging operations to literally reinvent her heart. Today, Dorothy is a typical kid. Like many little girls, she loves gymnastics, and now she's putting her whole heart into it.
