I've been getting my dental work done with Dr. Yu since summer 2007. He installed two gold partial crowns over two molars, filled some small cavities with composite, did a bruxing guard for me. So far, I'm really happy with the outcomes. He is really easy to talk to and is considerate of my financial situation, as I have no dental plan. What's more, he is really sweet and cheerful. He starts really early and works late and is still the same cheerful self. I would say that he is "called " to be a dentist.
