From the first minute of walking into Dr. Sun's office over 2 years ago to today, I have never had such superb health care and concern from a doctor! Except for my now deceased Dr. Irving Guttenberg! They both have a committment to superior care and concern for their patients! Dr. Sun is ALWAYS available and willing to work with you to find out what the cause of your illness is and to CURE it. She is relentless in determining what is wrong...she will do all the necessary testing and will fight for you to get what you need when you need it...she is by far one of the ultimate best ever!
