When she was in fifth grade, Margaret Mary “Maggie” Cleary said she remembers telling her classmates that she had prosecutorial ambitions. “I’ve always had a passion for having victims see justice,” Cleary, a UVA Law grad, said recently from her office in a building near the Culpeper Courthouse. She has served as an assistant commonwealth’s attorney for the county since 2018. Starting Feb. 1, Cleary will become an assistant U.S. attorney for the Western District of Virginia, based in Roanoke.
