Innovations in Pediatric Emergency Care

Stanford Pediatric Emergency Medicine is committed to research, innovation, and pediatric-centered care that creates an atmosphere of comfort for young patients and their families.

Our 25-bed, state-of-the-art pediatric ED is separate from our adult ED and our physicians are also Stanford School of Medicine faculty, representing some of the most innovative minds, trained in leading-edge best practices.

A Level I Pediatric Trauma Center, we offer comprehensive 24-hour emergency care that includes direct access to world-ranked pediatric specialists. 

Santa Clara County has recognized Stanford’s Marc Andreessen and Laura Arrillaga-Andreessen Pediatric Emergency Department as a comprehensive care center for its ability to handle a broad spectrum of medical emergencies in young patients.

Our pediatric emergency department melds expert care with pediatric-centered space

Stanford's Marc and Laura Andreessen Pediatric Emergency Department opened in 2022, and provides a bright, light-filled space abounding with images of nature and interactive installations designed to calm both patients and parents. The pediatric-focused space is fully staffed with board-certified pediatric emergency physicians and pediatric emergency-trained nurses and technicians. They provide the highest level of care for ailments ranging from ear infections to complications of chronic or congenital diseases, sports or school mishaps, to major trauma. Child life specialists, who distract and educate children during exams and procedures, have received graduate-level training. Read more.
