Missouri Injury Clinic keeps three rooms in the St. Louis metro, and this desk's only advice about choosing between them is geographic: pick the one you can drive to this week without the drive itself becoming the reason you put it off. Readers in north county are nearest Hazelwood. Everything below is as published on moinjuryclinic.com; hours are worth confirming on the call.

The daily closure, stated once more
All three rooms close from 12 to 2 every day. Readers who call at 12:30 and get no answer sometimes conclude the clinic is closed for the day and give up. It is not. Call before noon or after two. For O'Fallon on a Wednesday or Friday, the room is by appointment, which means the call matters even more.
What to say when the room answers
State that it was an auto injury. Give the date of the crash. Say where it hurts today in one sentence, and say whether your head was involved. Ask for the earliest opening. Entry 07 has the full script and the list of what to bring. If you already have an attorney, bring their contact so records can be sent where they need to go; you do not need to have decided anything about a claim before you get examined.
What the rooms do
The clinic publishes three lanes: auto injuries, meaning diagnosis and a treatment plan after a crash; TBI and concussion rehab after acute injury; and sports injuries. Joseph L. Hollingsworth, DC, runs the clinic, whose stated principle is putting the CARE back in healthcare. For the concussion lane it names vagus nerve stimulation, neurofeedback, Alpha Stim, sensory motor integration, exercise with oxygen, oculomotor rehabilitation, and cognitive rehabilitation among its tools. If your problem is in one of those lanes, you are in the right place. If it is something else, say so on the phone and let them tell you yes or no before you drive.
Which room, by where you are
This is not a service-area claim; it is driving sense. North county, Florissant, Ferguson, the airport corridor, and readers coming down I-270 from the north are nearest Hazelwood. South county, Affton, Oakville, Mehlville, and anyone who thinks of Tesson Ferry Road as home turf are nearest the Tesson Ferry room. St. Charles, O'Fallon, Wentzville, Lake St. Louis, and the I-70 corridor west of the river are nearest the O'Fallon room on West Terra Lane. Readers in the city or the central corridor should pick by traffic, not by loyalty.
