Mission
Based in Miami, Florida, SebastianStrong Foundation is a registered 501(c)(3) charity that honors the life of Sebastian "Sebs Ortiz (2000-2016) by increasing awareness of childhood cancer and raising money to fund research for less toxic, more targeted childhood cancer cures. This mission was born from the example of STRENGTH set forth by Sebs during his courageous 14-month battle with rhabdomyosarcoma. Since his passing, the Foundation bearing his name has bolstered the support of donors from across the country. SebastianStrong has awarded several grants to date for pediatric cancer research.
