Biography

Dr. Raphael Sun provides the full spectrum of pediatric surgery and fetal surgery as well as complex surgical oncology and colorectal surgery. 

He is an expert in prenatal anomalies and conditions such as congenital diaphragmatic hernia, sacrococcygeal teratoma, gastroschisis, omphalocele, congenital lung malformations and tracheoesophageal fistula. Along with pediatric surgery, he also specializes in fetal surgery including in-utero interventions such as twin-to-twin transfusion syndrome using laser photocoagulation. He also performs prenatal neural tube defect repairs fetoscopically.

Dr. Sun chose pediatric surgery because it allows him to make a lifelong difference in children’s health.  Children are born with conditions that they have no control over, and he finds it extremely gratifying to make an impact that can be life changing. As the father of two young children, who were born during his two-year pediatric surgery fellowship, Dr. Sun learned quickly what it felt like to be a parent. He understands how parents feel when they bring their children to the hospital.

Dr. Sun earned his M.D. degree from the Medical College of Virginia – Virginia Commonwealth University. He completed his residency in general surgery at Barnes-Jewish Hospital in St. Louis, where he also served as an administrative chief resident. During his residency, he completed his research fellowship at Washington University in St. Louis and his pediatric surgery fellowship at Texas Children’s Hospital in Houston. He received advanced training in perinatal/fetal surgery at Texas Children’s Fetal Center. 

When he’s not working, Dr. Sun enjoys spending time with his wife and children. He enjoys cooking for his family and traveling, and looks forward to spending time outdoors in the Pacific Northwest. He also serves in the United States Air Force Reserve.
