Dr. Madaan and his staff are tremendous - I was taking allergy shots from another doctor while my asthma was uncontrolled. Dr. Madaan stopped those, controlled my asthma first and then resumed them after updating my allergy profile. It has been now 11 months and I am completely off ALL medications! It does not get any better than this, as far as I am concerned. It was a waste of time and thousands of $$ to see my previous allergy specialist.... live and learn, I guess. See Dr. Madaan so you can get better before you get frustrated! From what I know, all severe and complicated cases are sent to him.
