Daniel León Calvo, or “Dani” as he is known to family, friends and supporters, is an 11-year-old boy who lives with his parents and older brother in Costa Rica. Dani, an honor student with a wonderful passion for life, has a rare blood disorder known as Pure Red Cell Aplasia or Diamond Blackfan Anemia. Only four other children in Costa Rica have this disease right now, and only 35 cases per year are diagnosed in the United States and Canada combined.

In 2016, doctors at Cincinnati Children’s Hospital in Ohio agreed to take on Dani’s case and perform a bone marrow transplant, a procedure that can completely cure Dani and allow him to live a normal life. #TeamDani is currently working hard to raise $1 000 000 to pay for this life-saving procedure and give Dani a long, happy and healthy life.
