The mission of Cooperative Elder Services, Inc. is to empower seniors and adults with medical or cognitive challenges to age-in-place by serving their health and socialization needs and providing support for families. Founded in 1978, CESI currently operates private, nonprofit adult day health programs in Arlington, Burlington, Concord, and Groton. We serve 600 at-risk seniors, adults with disabilities, and their caregivers, who reside in 54 cities and towns in the greater Boston area. CESI participants make 40,000 daily visits to CESI’s centers each year. CESI provides participants with an environment that supports their whole health: one in which they can socialize with peers, participate in meaningful activities, exercise their minds and bodies, learn to manage their chronic diseases, and maintain compliance with physicians’ orders. CESI programming furthermore provides participants’ family caregivers with the services and support they need to provide for their families’ physical, emotional, and financial well-being. CESI’s adult day health centers are staffed by licensed nurses, geriatric care and Alzheimer’s specialists, service coordinators, and program aides, with regular consultation by an Occupational Therapist and Registered Dietitian.
