The American Behcet's Disease Association (ABDA) is a 501(c)(3) nonprofit organization dedicated to supporting, educating, and empowering individuals and families affected by Behçet's disease, a rare and often misunderstood autoimmune condition. We provide trusted educational resources, patient support programs, advocacy at the state and federal levels, and fund initiatives that advance research, improve diagnosis, and expand access to care. Every donation helps us build a stronger, more connected community while working toward a brighter future for everyone impacted by Behçet's disease.

Originally known as the American Behcet's Foundation, the organization was established in 1978 in Orange County, CA, by Sheila Gregory, the mother of a young Behcet's patient. The name of the organization has changed throughout the years, but its mission of support, education, advocacy and research continues. In 1986 the organization was moved to Rochester, MN. In 1987, it was incorporated as a nonprofit organization under the name of American Behcet's Association (ABA). The Medical Advisory Board was established in 1988. The Internal Revenue Service granted 501(c)3 nonprofit status to the ABA in 1989. The name was changed to American Behcet's Disease Association (ABDA) in 1989, with the purpose of clarifying the nature and mission of the organization.
