In large cities, there may be two or three Area Agencies on Aging to cover the larger population. The Area Agency on Aging in your area may be called something slightly different. Your local library may keep a bulletin board of community services. While you are there, check for books describing health and social needs that can accompany aging. Check with the local senior center.
Many senior centers offer a hot noon meal.
Senior center staff are knowledgeable about local medical and social services. Your local Area Agency on Aging can provide information about local senior centers. Your local place of worship may be involved in directly providing services to older adults. They may also have volunteers available to visit home-bound persons. Most places of worship have at least one person on staff whose job it is to keep abreast of services available for older people in the community.
