The openingWhy this idea is overlooked
Allergy symptoms drive an enormous share of primary care and ENT visits, but board-certified allergists cluster in metros with long waits everywhere else; immunotherapy (allergy shots and sublingual options) is a multi-year, protocol-driven treatment that creates some of the longest patient relationships in outpatient medicine, and the operational model (testing day, then years of scheduled visits) is unusually predictable for a medical practice.
