Nikki Orlov
32, Lincoln Park
Third-year resident, appointed one of three chief pediatric residents July 2011–July 2012, at The University of Chicago Medical Center

With a 1-year-old daughter at home, it’s a wonder how she manages her work schedule: Seven months out of the year, Orlov works an average of 80 hours a week, and every fourth day she works a 30-hour shift. She says she couldn’t do it without the endless support of her husband and their families, among them a nanny who’s been in her family since Orlov herself was 6 months old and who is now helping her raise her own daughter. “I know Lilah’s being cared for by people who love her just as much as I do,” she says.
