I give this dentist very high marks. I don't care how big his waiting room is! He is very bright and knowledgeable and he does not rush treatment. I went to him back in 1998 or so and then moved to SF. After a bad experience (defective crown margin) with a dentist in SF, I went back to DR. Ho. The main reason I returned was that a crown he installed in 1998 has stood the test of time: no discomfort, eating problems, flossing problems, etc . . . After repairing the other dentist's work, we have moved onto some other areas of treatment. I had a broken tooth and he made a partial crown using CAD-CAM modeling. It works great, with no sensitivity. I did not feel like he ever pushed any treatments on me. I wish that I had stayed with him after I moved out of Palo Alto. It is well worth my drive from San Francisco to go to a dentist who is very well-educated but also technically proficient and careful.
