JCCoA is an advocacy group of volunteers whose mission is to identify and address the needs, concerns, and issues of older adults in Jefferson County, Colorado. Jefferson County Council on Aging was formed in 1974, and is the longest operating and largest county council on aging in Colorado. We welcome visitors and new members at our monthly meetings, which are open to the public. Council meetings are held the second Thursday of the month from 2 to 4 PM.
