When a family has concerns about a child’s growth and development, waiting for answers only prolongs the apprehension. Our clinical mission is to provide timely endocrine services to our patients, offering quality treatment and early intervention while minimizing delays.

The Division of Pediatric Endocrinology is dedicated to training future healthcare professionals to properly diagnose and treat children with a wide variety of conditions, including growth, transgender health, diabetes, and disorders of puberty, weight, and of the pituitary, thyroid, parathyroid, and adrenal glands.

Under an affiliation agreement with UCI Health and the UCI School of Medicine, our faculty members provide training and clinical services at Gottschalk Medical Plaza on the UCI campus, and at CHOC Children's Hospital of Orange County, and a Pediatric Endocrinology clinic in Torrance, the south bay of Los Angeles.
