Do you live near a military base/post? I know with the AF they contract docs on top of their ADAF docs. If so, contact that local installation hospital, specifically the allergy unit, explain your situation and ask if they use a contracted allergist. If they say no, ask them who they use as a Tri-Care referral.
Military members will be referred out to Tri-Care insurance providers. Many of these docs are retired or Guard/Reservists. They know exactly what the military is looking for when it comes to waivers because if the military has to refer them out (economy) it means a higher level of testing that they don't or can't offer on base/post.
I would add that to remember DoDMERB DQs, but it is the commissioning source that will be in charge of the waiver process. IOWS, be careful reading into if someone did not get a waiver. USMA is a different commissioning source than AROTC. AROTC may grant a waiver, whereas, USMA may not. Vise a verse.
