William was an incredibly funny, exuberant, smart, kind, loving, and, of course, a handsome five-year-old boy who loved Legos, Star Wars, Super Heroes (especially Batman), dinosaurs, and animals. He had just finished kindergarten when he was diagnosed with medulloblastoma, the most common kind of pediatric brain cancer.

Like his hero Batman, William faced extreme hardship with extraordinary strength, courage, and determination. He underwent numerous surgeries, 6 ½ weeks of radiation, and chemotherapy, only to relapse two months after completing treatment. In the end, he died at the age of seven, not from cancer but from the terrible complications caused by high-dose chemotherapy with Stem Cell Rescue. He was unable to recover and died in January 2017. From that tragic day, the nonprofit William’s Warriors Inc. (82-3254490) was created to help other pediatric cancer patients and their families.

The Foundation has a 2-part mission: www.williamswarriors.org

The first is to fund pediatric brain cancer. William’s Warriors supports the Wechsler-Reya Lab's research at Columbia University's Herbert Irving Comprehensive Cancer Center. The Wechsler-Reya Lab "focuses on improving outcomes for patients with medulloblastoma, the most common malignant brain tumor in children".

The second is to improve the quality of life for all children undergoing cancer treatment. We supply Cohen Children's Medical Center, Stony Brook Children's Hospital, and NYU Langone Hospital Long Island with art and craft supplies all year long, as well as provide 1st-time admission Creative Care Kits for children facing their 1st inpatient treatment. Additionally, we provide free Creative Care Kits upon request to children receiving treatment in New York State.
