Why look by county rather than by town?
Because insurance networks, Medicaid plans and health districts are drawn by county, and because the practice nearest you may be in the next town rather than your own. This page ignores the town boundary and lists the whole county in one order: the practices most likely to answer first, closest first inside each group.
How do I ask several of them at once?
Tick the practices you want on this page and send one request. The ones that have claimed a listing answer by email; the rest are told a patient is asking for them, and their own page carries the phone number. It is free and there is no account.
