Dr. David Lazar is a pediatric surgeon at Rady Children's Hospital-San Diego and an assistant professor of surgery at UC San Diego School of Medicine.

Dr. Lazar earned a Bachelor of Arts in biology with honors from the University of Pennsylvania, then graduated from medical school at Baylor College of Medicine. He excelled at his general surgery residency at UC San Diego, winning multiple teaching awards and garnering departmental and campus-wide recognition for his efforts in medical student and resident education.

He served as administrative chief resident before pursuing two years of research in wound healing and fetal surgery at Texas Children's Hospital. Following his residency, he completed his pediatric surgery fellowship at Texas Children's Hospital and Baylor College of Medicine, where he gained comprehensive exposure to fetal and neonatal surgery, surgical oncology and minimally invasive surgery.

Dr. Lazar's clinical interests include prenatal counseling and intervention, caring for children with thoracic and abdominal congenital anomalies, and extracorporeal membrane oxygenation (ECMO).
