not the exact same webpage, but I also found the same info on other webpages (searched "AAP catch program"): https://pediatrics.aappublications.org/content/143/6/e20182551

The Community Access to Child Health (CATCH) Program: A 25-Year Retrospective

Funding CATCH began with support from generous donors. It continues to rely on charitable gifts to sustain its grant program. In addition to strategic AAP Board support through the operating budget and allocations from the Friends of Children Fund, CATCH has sustained itself by philanthropic investments from Pfizer, the National Dairy Council, and the Magic Pebble Foundation. Additionally, the personal philanthropy of many AAP members has supported the ongoing effectiveness of the program.
