Dr. Nguyen is a very reliable doctor. He will take the time to answer all of your question so you will not feel like you are being rush. It easy to get an appointment with him. And if he is ever in doubt, he will refer you to a specialist immediately. His staff are wonderful too. The wait at his office has never been more than 15 minutes. Also, he will take the time to return your phone call too. Hardly any doctor does that any more.
