The Tri-County Office on Aging (TCOA) has been the leader of assistance, advocacy, and planning for senior citizens and their families since 1974. Serving Michigan's Clinton, Eaton and Ingham Counties and the Cities of Lansing and East Lansing, TCOA is the state designated Region VI Area Agency on Aging. Senior citizens, family members, hospital staff, home health agencies, and neighbors depend on TCOA for direction, referrals and services for our community's aged disabled adults.
