  • Needy Children’s Christmas Fund – Operated by First United Methodist Church of Denham Springs, this fund assists families with children at Christmas. The church asks local elementary school principals to submit the names of two needy families. The church then calls each parent regarding the children's wants/needs for Christmas. The gifts are delivered the week before Christmas so that the parent may put them out on Christmas morning.
