Erin Santos is a freelance writer, blogger and president of the Isabella Santos Foundation (ISF), a nonprofit organization dedicated to raising funds for neuroblastoma and other pediatric cancers. Erin and her husband founded ISF when their 2-year-old daughter, Isabella, was diagnosed with neuroblastoma. Though Isabella passed away in 2012 after a five-year battle, the foundation continues its mission in hopes of saving other children. Erin blogs about life during and after Isabella's cancer fight on her blog Summer of the Dragonfly.
