Rosemary Powers Goodwin, who ran a private psychotherapy practice for about two decades, died June 3 at her home in Chevy Chase. She was 72.

The cause was brain cancer, said her husband, Frederick K. Goodwin.

Mrs. Goodwin practiced from her home office from the early 1980s until shortly before her death. From the late 1970s through the early ’90s, she was a clinical social worker and psychotherapist with Georgetown University Medical Center’s substance-abuse treatment program.

Rosemary Julia Powers was born in Richmond, Minn. She settled in the Washington area several years after receiving a bachelor’s degree in history from Saint Louis University in 1963. She received a master’s degree in history from American University and a master’s degree in social work from Catholic University.

Mrs. Goodwin was a volunteer psychiatric social worker at Montgomery Hospice and a lector at the Shrine of the Most Blessed Sacrament, a Catholic congregation in Washington.

In addition to her husband of 49 years, Frederick K. Goodwin of Chevy Chase, survivors include three children, Kathleen Hayden of Severna Park, Frederick K. Goodwin Jr. of Annapolis and Daniel C. Goodwin of Springfield; a sister; a brother; and 10 grandchildren.
