The Division of Pediatric Hematology/Oncology is one of 18 divisions in the Department of Pediatrics of the Stanford University School of Medicine, and currently includes 30 faculty members.  Our faculty are in the midst of one of the most stimulating and diverse intellectual environments, which embraces innovation and celebrates unconventional ideas and new perspectives. The Division faculty together strive to excel at the three traditional academic medical center missions:  outstanding clinical care, excellence in training and education, and impactful research. 

The faculty are organized in two sections, hematology and oncology, and are supported by a partnership between Stanford University School of Medicine, Stanford Cancer Institute  and Lucile Packard Children’s Hospital with Stanford Children’s Health Network. 

This year a new inpatient hospital will allow for expansion of patient care along with clinical and translational research. As well, new research and academic buildings will start construction in 2019 to house growing programs. 

Three faculty members serve two partner sites in the Northern California Bay Area, California Pacific Medical Center (San Francisco) and John Muir Hospital (Walnut Creek), with the remaining faculty located on the main campus (Palo Alto). 

Our renowned faculty are experts in all areas of the field of pediatric hematology and oncology,  and are members of a newly established world-class immunotherapy program. Our faculty play a significant role on numerous local, national and international organizations.
