Dr. Song is highly knowledgeable, caring, informative, experienced, and the list goes on and on. We have been going to him for about five years. He gives us enough time and never rushes, like some other doctors. He is very thorough and detailed, and wants to make sure that he is addressing our issues and questions very effectively, and taking complete care of his patients at the same time. If you guys are looking for an allergist, please please please go to Dr. Song.
