Overview

Dr. David Freyer joined Children's Hospital Los Angeles in January 2008. As Director of the LIFE Program, he oversees all aspects of its services, which include clinical assessments of more than 350 patients annually, research regarding their long-term outcomes, and training of fellows, residents, and other health care professionals in the care of childhood cancer survivors. His clinical and research activities have focused principally on cancer survivorship and cancer control, including the recognition, management and prevention of short-and long-term morbidity of treatment, as well as health care transition for young adult survivors of childhood cancer, adolescent and young adult (AYA) oncology, palliative care, and decision-making at the end of life. Dr. Freyer is a member of the Children's Oncology Group where he serves as chair of the AYA Committee, on the Steering Committees for the Survivorship & Outcomes and Cancer Control Committees, and on several protocol and administrative committees. Dr. Freyer graduated magna cum laude from DePauw University, obtained his medical degree from the Des Moines University College of Osteopathic Medicine and Surgery, and completed post-graduate medical training at Chicago College of Osteopathic Medicine and Hospitals, Rush University Medical Center and the University of Michigan Medical Center. In 2007, he obtained a MS degree in Clinical Research Design and Statistical Analysis from the University of Michigan School of Public Health.
