Mary Ann Clark, 74, left her building in Union around 5 a.m. Friday. Her coworkers say that is when she normally leaves for work to get to her job in New York City.
Clark's co-workers called police when she didn't show up for work on Friday morning.
"It's not like her at all, she's very sharp, she basically runs the place - she's the office manager, she's kind of like a mother to all of us, so we're very worried about her," said co-worker Hilary Ginther.
Ginther says Clark does not have any immediate family in the area.
Clark works at 'CM&F Group' in TriBeCa. Anyone with information is urged to call Union Police.
