I've been pleased with this practice in NJ. I see Dr. Graffino for allergies and like her a lot--you can scroll through the drs in that link. The staff are really nice too.
National Jewish in Denver, co is at the forefront of allergy/immunology I believe, and may be worth a consult visit. They are geared to taking out of state patients.
Asthma/reactive airways, allergies, irritants that aren't allergens, gerd, viral and bacterial infections--they're interwoven with cause and effect, and it is hard- to say the least- to tease out what is going on.
