The Crohn's & Colitis Foundation is a non-profit, volunteer-driven organization dedicated to finding the cures for Crohn's Disease and ulcerative colitis, and to improving the quality of life of children and adults affected by these diseases.

It was founded in 1967 by Irwin M. and Suzanne Rosenthal, William D. and Shelby Modell, and Henry D. Janowitz, M.D.

The Colorectal Cancer Alliance was founded in 1999 as the Colon Cancer Alliance, by a group of 40+ survivors, caregivers and friends who saw the need to educate the public about colorectal cancer and provide support to those affected by the disease.

Though it began as a simple online support group, the passion and vision of those involved began a nationwide movement. Following the sudden death of integral founder Marshall Kragen and the National March to Conquer Cancer in 1998, the group intensified their efforts.

Communicating by e-mail and meeting in online chat rooms, they created the organization’s name, logo and mission. From there, they built the legal and administrative framework, providing the foundation for all current Colorectal Cancer Alliance initiatives.
