Using a biopsychosocial framework, this article presents cutting-edge issues of older adulthood and considers emerging roles of social workers with older adults and their families. Research, education, and policy perspectives that will advance social work knowledge, skills and resources in aging are proposed. Social work as a profession is challenged to lead the way in making "everything old new again."
