Share: Kristal Espinoza wakes up at 2:30 a.m. to her iPad alarm to get ready to go to work. She takes a shower, brushes her teeth, and drives from the San Gabriel Valley to South Los Angeles for work when the sun is nowhere in sight. She doesn’t even eat breakfast because there’s not enough time until her first break. Her shift at the hospital cafe starts at 4:00 a.m., and doesn’t end until 12:30 p.m. Follow:
