Where Pediatricians Work Some pediatricians work in an office, either alone or with a group of other doctors, while some work in a hospital, health maintenance organization, clinic, or medical school. Still, others work as locum tenems doctors, traveling around a city or around the country, filling in for other doctors on a part-time basis.
A pediatrician is a doctor who takes care of children from birth to age 21. Most pediatricians will say they love children and want to help children, adolescents, young adults and their families. Pediatricians have careers that are flexible, varied and rewarding.
