Mark Edward Hollingsworth, an accountant and co-founder of a health care company, died July 25 of lung cancer at his West Friendship home. He was 48.
Mr. Hollingsworth was born in Washington and raised in Bethesda.
He attended St. Albans School and graduated in 1980 from Walter Johnson High School in Bethesda. He attended St. Mary's College and the University of Maryland, College Park, and earned a bachelor's degree in accounting from Towson University.
A certified public accountant, Mr. Hollingsworth worked with several accounting firms in Baltimore before co-founding Ruxton Health Care Inc., a Columbia-based company that owns and operates nursing and convalescent centers in several Middle Atlantic states, with Eamonn Reilly.
