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.
