I also think you'll like their record keeping protocols and promptness. As I said they process a lot all of the time so IMO, and remember I'm a native New Yorker, it was the most polite, responsive and effective support staff of any medical place I've ever been in.
They do this cool thing with scratch tests with pen and a piece of tape to take a film of the boundaries of the actual wheal. Sicherer, and Dr. Li were the two main doctors we interacted with and busy as they are they always replied timely to questions via email. The nurses were always great with the kids. The one con for me was the effectiveness of Sicherer's researches studying under his wing--didn't care for them saw too much of them initially. Sicherer himself is an incredible person and was a pediatrician first before researcher with DS1. But if I had to do it over again Dr. Nowak would have been an equally great choice. She's been a primary author on many papers herself.
Every time DS1 went in for an appointment he also got to go to a museum
and Times Square Toys R Us. Remember to keep your receipts for travel costs it should be tax deductible.
The Northeast being what it is geographically Boston would be an equally viable option IMO. I don't know what that does to your drive. While we didn't bring the kids to Harvard/Brigham/CH, I was a patient at B&Y/Harvard. The discovery coming out of allergy there seems... accelerated. In relation to a response post I owe ajas, I idly wonder if the internal review board fast tracks Boston because they seem to get more 'experimental'. They also seem to have more clinics for kids in how to deal with aspects of life with allergies. You get the added bonus of NEAQ, MOS, art, MIT natural history, and all the FA restaurant laws. We couldn't because too many top 8 allergens but with fewer allergens it's probably enjoyable.
