After months of getting the run around - 2 rounds of antibiotics and 2 rounds of steroids. Dr. Daian is the doctor who ordered the chest x-ray that showed that I had a mass in my chest. I have bee a patient of hers for over 20 years.

Dr. Daian should be voted "BEST DOCTOR OF THE CENTURY". She is kind, caring, compassionate, knowledgeable and goes way beyond to see that she gives her patients the best care she can. She always returns phone calls in the same day. She is by far, the BEST DOCTOR I have every gone to and recommended her to friends and family. She takes the time to listen and help which most doctors don't do nowadays. She never rushes you and you can ask her all the questions you have and she will figure out the best solution to your illness. I WISH there were more like her in the medical profession. Most doctors give you the scheduled 10 minute visit and refer you to a specialist. They don't even 'try' to help or figure out what is wrong. Dr. Daian is truly 'one of the best" in the medical profession.

I have never met a doctor with such empathy and genuine concern, Dr. Daian goes over and above the normal expectations, and beyond..she takes her time and listens to everything said..I can not rate her high enough. Is she a doctor? Or, an angel? I think both! I am most grateful to her, and highly recommend her to anyone!

I cannot say enough about Dr. Christina Daian!! It is very hard to find a doctor who has brilliance and a bed side manner.. She is absolutely amazing! Even her staff is pleasant to deal with.. That never happens.. She is also very accessible, she even called to check on me over the weekend! That is so unheard of this day and age.. Choose her!,
