For 43 years Wilbert Mason, MD, MPH, dedicated his life and career to advocating for the well-being of children. He solidified his legacy in the area of pediatric infectious diseases through his prominent research and clinical care of patients with Kawasaki disease.

His collaboration on Kawasaki disease with cardiologist Masato Takahashi, MD, began in 1979. His clinical, epidemiological and treatment studies of patients with Kawasaki disease made him one of the nation’s most sought after physicians specializing in the disorder.

Dr. Mason was appointed to the faculty in 1974 and in 1989 was promoted to professor of Clinical Pediatrics at the Keck School of Medicine of the University of Southern California. He has continued in this role for 24 years. In 1995 he earned his master’s degree in public health (epidemiology) from the University of California, Los Angeles. He has been an outspoken advocate of education surrounding the importance and safety of immunizations. Internally at CHLA, his involvement with antimicrobial stewardship has led to safer policies and improved outcomes. Dr. Mason has been an exemplary teacher and mentor for decades of medical students, residents, fellows and faculty, demanding rigor and excellence in medical knowledge and skills with warmth and a sense of humor; he has won the Phillip E. Rothman Award for outstanding teachers from the CHLA Residency Program twice.

From 2000-2009, Dr. Mason served as the head of the Division of Infectious Diseases at Children’s Hospital Los Angeles. He has served on numerous committees and boards throughout the hospital and was the first chief medical quality control officer in 2009. He was also the medical director of Quality Systems Management and Resource Utilization. He has received countless awards for his research and clinical work and has been named a “Best Doctor” on prestigious lists for decades.
