The Arc Portland Metro was founded in 1953 as a grassroots disability justice movement by a small but deeply invested group of parents of children experiencing intellectual / developmental disabilities. During a time when there were few effective resources to meet the needs of this community, they emerged as a growing body of tireless champions for early disability rights and resources. Anchored in these enduring principles of equity, inclusion, and opportunity, The Arc Portland Metro continues the work of advocacy, support, placemaking, advancement, and empowerment to help people experiencing IDD achieve their greatest potential.

The Arc Portland Metro is a local affiliate chapter of The Arc of the United States and The Arc Oregon.
