For more than 60 years, The Arc has been on the front lines in making change happen for people diagnosed with intellectual and developmental disabilities. The Arc is the nation’s leading advocate for all people with intellectual and developmental disabilities and their families and the premier provider of the supports and services people want and need. The committed men and women on our board of directors are representatives from each affiliated chapter. They have experienced both the challenges and the triumphs associated with intellectual and developmental disabilities firsthand. Their personal stake in The Arc’s mission provides our volunteers, members, and professional staff with wisdom, inspiration, and guidance.
