I worked chairside for Dr. Hing for three years in the mid 90's and can personally attest to his abilities as a dentist. He is an artist and will not rest until your teeth are exactly the way you want them.
The only reason I left was because I wanted to pursue a different career path. Dr. Hing has remained my dentist and although I live in Napa now, I still travel to his office and will not let anyone else work on my teeth, unless I need a specialist. By the way, he only refers his patients to the best specialists as well.
