My Passion for Healthcare

Over the course of my training, I have come to understand that the various aspects of an experience can enhance the quality of a patient’s medical care. I believe every pediatric patient encounter is an experience with three sides - the patient’s, the parent’s and the physician’s. This has been my guiding principle as I approach the goals and concerns for each patient and parent.
