NF, Inc. is a national organization whose mission is to create a community of support for those affected by NF through education, advocacy, coalitions, raising public awareness, and supporting research for treatments and a cure; sponsor a limited number of local groups.
Children's Tumor Foundation
The Children’s Tumor Foundation (CTF) is a non-profit medical foundation dedicated to improving the health and well-being of individuals and families affected by the neurofibromatoses. Look under "How You Can Help" to find a local chapter. The CTF sponsors an annual summer camp for children with NF.
