Empowering Children with Pediatric Cancers through the Power of Patches! The Oliver Patch Project (OPP) is a 501(c)(3) nonprofit corporation whose mission is to create a fun, engaging platform where children with childhood cancers and their families can connect through a series of unique patches created by artists and designers just for them. We empower kids to find their inner warriors, as they endure life changing milestone events, by providing a bit of sunshine throughout their entire cancer journey from discovery through completion. The project is supported by donations and all the fun is provided to our Warriors 100% free of charge. We believe in the power of positivity to promote healing.
