Nancy Wlodarski, 55, an events manager for the National Multiple Sclerosis Society who presided over its fundraising walks, died Jan. 3 at her home in Chesapeake Beach, Md. She had breast cancer.

Her husband, Ed Boyle, confirmed the death.

Ms. Wlodarski spent much of her early life and career in Ohio, where she became an economic development specialist for the Cleveland suburb of North Olmsted. She was an aide to the mayor, Boyle, whom she married in 1996.

She settled in the Washington area in 2001 and worked until her death for the local chapter of the National Multiple Sclerosis Society. She led its annual fund-raising walks, which earned more than $1 million in donations each year, her husband said.

She remapped the walks to make them accessible to the handicapped and started two new walks, in Rockville and Bowie, her husband said.

Nancy Justine Wlodarski was a native of Euclid, Ohio, and a 1979 communications graduate of the University of Dayton in Ohio.

She was a resident of Chesapeake Beach in Calvert County and a member of St. John Vianney Roman Catholic Church in Prince Frederick. In her last months, she volunteered to assist the church with its food bank.

Her first marriage, to Pete Jelenik, ended in divorce. Survivors include her husband, Ed Boyle of Chesapeake Beach; a stepdaughter, Kristen Boyle of Maumee, Ohio; her mother, Victoria Oberstar of Euclid; a sister; a brother; and a grandson.
