Dr. Park is a great dentist and he seemed like a really hard worker. He didn't smile much, probably because of all the kids he has to deal with every day, but he is such a nice person and very concerned about everyone. His sister was a hygienist in the same office and she was very thorough (and did a better job than most of the other ones). I will, however, agree that the front office staff couldn't care less about anyone. They were always pretty cold. I am now 30 years old and my mouth is (almost) cavity-free thanks to the great care I received from Dr. Park for so many years. I'm sure he will be retiring soon, and that will be a great loss to the Portland dental community.
