How We Assign Your Clinic
Every community we serve is matched to exactly one of the four clinics, and the match is made with routed drive data rather than a radius drawn on a map.
For each town we route a real trip from the town's village hall to the clinic's street address using
OSRM, an open source engine that follows the actual road network. That returns a driving distance and a free flow travel time. We then widen the time into a range so it reflects ordinary traffic rather than an empty road, and the town's own page records the conditions behind its range, such as Route 59 congestion for
Plainfield or the Metra BNSF alternative available from
Hinsdale.
Two rules keep the list honest. A community that sits between two clinics is not assigned by guesswork; it stays under review until the routing evidence clearly favors one, which is why some nearby towns are not published here yet. And the four clinic cities never get a community page of their own, because each already has a clinic page.
The clinic named on a community page is the one the road network puts closest to you. If another location suits your week better, all four are listed on
the clinics page.
