He is really smart and current on the research. He figured out a problem my daughter had with chronic sinusitis that no one else could. He found a defect in her immune system using a state-of-art, simple blood test that most other doctors I meet have not even heard of. If you live far away, you may not want to go to him for the 'standard' allergy problems because if you need shots driving that far twice a week could be hard. But, if you've got a stubborn asthma problem or a kids who is sick all the time and no one knows why, he's really the best I've seen.
