Dr. Tsai has done extensive dental work for me over the many years I've been his patient, and his technical skills are the best I've ever had, and I've had 40 plus years of major dental problems! He did my front teeth crowns last year, and my smile has never looked better. Every crown and bridge he has ever done for me have been a perfect fit from the start, because he really takes time to make sure the crown prep work is done correctly. He's very much the perfectionist while working in my mouth! Never, ever had a bad experience with his dental work. He does the teeth cleaning so that he can fully examine your entire mouth, while a hygienist does the polishing. He's very careful to ask how you're doing through a procedure, wanting you to have a comfortable experience, and he will provide nitrus oxide if requested. His office staff is wonderful, friendly and very helpful. His wife, Dr. Kelly, is also extremely skilled, kind, friendly and a great dentist also. Even though the office style is very dated, and he can have a seeminly gruff personality at times, he's very caring and kind. I highly recommend Drs. Tsai and Kelly, and their wonderful office staff.
