My son saw Dr. Wasserman for about 6 months quite frequently as we tried to get his allergies under control. (Peanut and pine nut severe; constant respiratory issues the fall/winter/spring around his first birthday.)
Wasserman was very thorough, and in a life-threatening allergic reaction, this is the guy I want treating my son.
For the routine maintenance stuff, he's too aggressive with medications for my taste. We still check in with him, and I'm glad to have him on my roster of medical professionals, but he's not our first line of defense for anything short of anaphylaxis. I love that he personally answers emails within 24 hours. We adjusted dosages that way when the allergy meds were making my son too sleepy.
I use a lot of homeopathic stuff, take the kids to the chiropractor, feed all natural/mostly organic food with very limited sugar, and try to keep dust-collecting stuff away from the kids bedrooms (carpet, curtains, stuffed animals, etc.).
I started the chiropractor after the meds (and probably the summer sunshine and fresh air) had gotten the respiratory issues under control. I used the meds faithfully for about 2 months, and now only use them if my son is really congested or dripping alot to make sure he can sleep. The chiropractor has turned out to be more effective at reducing the respiratory issues and ear infections than any medication. I highly recommend chiropractic as a supplement to traditional medicine. There are a lot of things the chiropractor can nip in the bud which left to run rampant would end up needing antibiotics.
Good luck. The key is a doctor you feel confident in, who fits with your style, who also has a reputation of being good at what he does. The best way to get a referral is to ask a doctor you know in the same specialty, but who doesn't directly compete for patients. So if you need a pediatric allergist, ask an adult allergist (who doesn't see kids) who they would take their own child to.
