Valerie Johnson doesn’t think there’s anything remarkable about her or her job. She may be the only one who thinks so. Hired as the university’s first and only female plumber almost 30 years ago, she is still the only female plumber on staff with Johns Hopkins Facilities and Real Estate. She and electrician Tiiu Maiste, JHFRE’s only female electrician, are part of the Facility Operations team that provides day-to-day maintenance for all the nonhousing buildings on the Homewood campus.
