Preston’s League is a childhood cancer non-profit, volunteer based, 501 C-3 charitable organization committed to providing basic necessities to patients and their families through a weekly wish list program within the Duke Pediatric Transplant and Cellular Therapy Department (DPTCT). Our wishlist program is every week, 52 weeks a year. Preston's League was founded by Celeste and James Winslow in memory of their son, Preston, who passed away following a long battle fighting Acute Myeloid Leukemia.
