Sue Taylor Brown, the former executive director of the Maryland Psychological Association, died July 10 at her home in Columbia. She was 73.

The cause was metastatic melanoma, after a lifetime of living with Fabry disease, an inherited enzyme disorder resulting in the inability to metabolize lipids, said her husband, Robert Brown.

Ms. Brown worked 28 years for the Maryland Psychological Association before her retirement in 2003. In 1986 and 2000, she received awards from the American Psychological Association for outstanding achievement by a state or provincial psychological association chief.

Patricia Sue Taylor was born in Seattle. She graduated from the University of Oregon in 1961 and received a master’s degree in psychology from the University of Iowa in 1962.

She was an officer with the League of Women Voters in Takoma Park and Columbia. She was a founding member and president of the Pro Bono Counseling Project, which offers free mental health treatment to needy families and individuals in the Washington and Baltimore areas.

Ms. Brown was a 40-year resident of the Washington area.

Survivors include her husband of 50 years, Robert A. Brown of Columbia; three children, Karen E. Brown of Cheshire, Conn., James R. Brown of Media, Pa., and Kenneth G. Brown of Iowa City; a stepdaughter, Kaya A. Brown, of Santa Cruz, Calif.; a brother; and seven grandchildren.
