Physician Bio

Dr. Tang says that since the birth of his first child, he has realized how much he truly loves being a father and a pediatrician.

“I believe that the practice of pediatrics should blend the science of medicine with the humanity of family, sprinkled with a touch of humor. I do take my job seriously and I am aware that parents have entrusted me with the care of their child’s well-being. I am also aware that there are many ways to treat a given illness or concern and we, as physicians, must tailor the management in the context of the patient and family.”
