Pediatrix Medical Group, Inc.
A physician-led medical group that provides specialized care for women, babies, and children, staffing and managing hospital units like neonatal intensive care units (NICUs) across the country. Founded in 1979 by two neonatologists as South Florida Neonatology Associates, it later renamed itself MEDNAX before returning to the Pediatrix name in 2022 — a word built from "pediatrics." Its clinicians care for roughly one in four babies born in the United States.
