health personnel through more efficient intervention strategies, including teamwork and case management approaches. In 1969 Barker co-founded, with psychiatrist-psychoanalyst Karl D. Hawver M.D., the Potomac Psychiatric Center in the Washington D.C. suburbs. The clinic focused on treating individuals and families with mental health problems and family relationship issues. Barker specialized in family therapy, couples therapy, and group psychotherapy. In the clinic's Capitol Hill office in Washington, Barker treated the families of many U.S. Members of Congress and other government officials. In 1979, Barker joined the faculty of The Catholic University of America, where he taught master's and doctoral students and guided their dissertation researches. During this time he wrote over 100 articles in professional journals, created and edited the Journal of Independent Social Work from 1986–1991, and produced textbooks on couples therapy. He was consultant to the Ladies Home Journal column “Can This Marriage Be Saved” in 1987 through 1989 and its counselor-expert. He wrote a best selling book “The Green Eyed Marriage” which led to his conducting a series of workshops for people and their families with jealousy problems. Together with faculty at Catholic University he helped establish two new schools of social work in Santiago and Valparaíso, Chile, and he taught courses at the Escuela de Trabajo Social at the Pontificia Universidad Católica de Valparaíso for three years beginning in 1988. Since 1990 he has focused his career to the development of The Social Work Dictionary and other publications. He has also worked extensively as a consultant to organizations that write questions for professional state licensing boards, to testifying in courtrooms about family and custody issues, and as a researcher and advocate for homeless persons. Barker is married to Dr. Mary Elizabeth Donovan, formerly of the education faculty at the University of Puget Sound. They have three sons and one daughter. Case management innovations Early in Barker's career in the 1960s, President Lyndon Johnson's Great Society programs necessitated tremendous increases in the numbers of social service and mental health workers. The National Association of Social Workers (NASW) was awarded grants from government agencies to help find ways to remedy these shortages. Barker and Thomas Briggs were employed to conduct and administer these studies. They observed numerous state and federal institutions and experimented with different ways staff members could help hospitalized clients and their families. The Barker-Briggs model of using teams to provide these services was later used as
