Doris J. Martin, 82, a former medical laboratory technician who later became a real estate office administrative assistant, died March 13 at Fairfax Nursing Center.

She had Alzheimer’s disease, said a son, Mitch Martin.

From 1990 until her retirement in 1995, Mrs. Martin worked as an administrative assistant for a Coldwell Banker Real Estate office in Annandale. In the 1980s, she worked as a medical laboratory technician at Sentara Potomac Hospital in Woodbridge and American Medical Laboratories in Fairfax.

Doris Jean Sharp, a Los Angeles native, was a 1952 education graduate of California State University at Long Beach. She taught grade school in the Los Angeles area before moving to the Washington area in 1969.

She was an Inova Fairfax Hospital volunteer and an elder of Clifton Presbyterian Church.

A longtime Clifton resident, she moved to the Fairfax Nursing Center in December.

Her marriage to John Martin ended in divorce. Survivors include four children, Rand Martin of Sacramento, Mitch Martin and Eric Martin, both of Clifton, and Kristin Bennett of Fredericksburg; 10 grandchildren; and two great-grandsons.
