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.

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.
