About Us

A Pediatric Academic Medical Center

CHLA is a provider of more than $125 million in community benefits annually to children and families. As the first and largest pediatric hospital in Southern California, CHLA relies on the generosity of philanthropists in the community to support compassionate patient care, leading-edge education of the caregivers of tomorrow and innovative research efforts that impact children at our hospital and around the world.

Keck School of Medicine of the University of Southern California

Children's Hospital Los Angeles is among the world’s finest pediatric keck_logo.jpgacademic medical centers due in large part to its association with Keck Medicine of the University of Southern California for three-quarters of a century.
