WWP
I started with what you linked then went directly to WWP financial statement, which I have cut and pasted.
We contributed from the beginning when they were giving out backpacks at the hospital and now contribute $19/mo. I’m statisfied they don’t abuse the public who donate.
WWP is a registered 501(c)(3) nonprofit organization with headquarters in Jacksonville, Florida. WWP’s federal ID number for donations is 20-2370934. View IRS Determination Letter.
