Dr. Yen is my dentist and he is an absolutely wonderful man and an incredibly good professional who gave me no pain at all besides tiny tiny discomfrt which is usual, and I had to get a lot of work done because I had not seen my previous dentist for several years, and now, everything is great and I have no worries at all if I need something done to call up my friend Dr Yen because I know he is the A+ #1 very best in the practise. This is true. I recommend him highly. And, just as a co-incidence, today is his birthday 16-may, so wish him a happy birthday if you are in touch, and tell him "Joe Quinn" sent you. (and try the massage vibration chairs to relax, before and even during work... superb luxury treatment if you ask me, and very convenient location right in the heart of midtown manhattan, very reasonable and professional. -- JQ
