Dr. Hiura gave me gum grafting surgery on 3 tooth. He's very experiened, friendly and gentle, so are the staff, the whole experience was as good as it gets (given it's not the most fun experience.) He even called me the next day (on Saturday) to make sure everything was ok.
If you have any periodontal work done, I'd highly recommend him. I don't have much experience with periodontists (thank god!), I'd say he's the best in town.
