    Dr. Quon, as always, conducts a thorough examination while providing a running commentary on what he's seeing and his thoughts/diagnosis relating to the exam. He has an excellent bedside manner and is never condescending or obtuse in his explanations, particularly when answering any questions or concerns I might have.

They both not only demonstrate a very high level of professional skills, but at same time are very presentable and caring in their interaction with you.
