Key takeaways
- Three rooms, three numbers. Every room closes from 12 to 2 daily, so call in the morning or mid-afternoon.
- Hazelwood is the nearest room for most readers of this desk. Tesson Ferry serves the south, O'Fallon the west.
- Hours are published by the clinic and worth confirming on the call. We print only what moinjuryclinic.com prints.
- If the drive itself is a problem because of light or fog, get a ride. Nobody at the desk will think that is strange.
There is a reason this desk says "the room you can drive to this week" instead of "the nearest location." Nearest is a map question. This week is a headache question. The room that is ten minutes farther but has an opening Thursday is the right room. Here are the three, in the order most of our readers live.
North County, Hazelwood
14 Village Square Shop Ctr, Hazelwood, MO 63042. (314) 627-1411. Monday through Thursday 9am to 6pm, Friday 9am to 12pm. Closed daily 12 to 2.
Hazelwood is the room nearest most readers of this desk, which covers the north metro. Friday is a half day; if you call Friday morning, ask about the following week rather than the afternoon. Book Hazelwood →
South County, Tesson Ferry
11144 Tesson Ferry Road, Suite 200, Saint Louis, MO 63123. (314) 530-5480. Monday through Thursday 9am to 6pm, Friday 9am to 12pm. Closed daily 12 to 2.
The south room keeps the same hours as Hazelwood. If stairs or an elevator are a question for you this week, ask on the phone. Book Tesson Ferry →
Lake St. Louis, O'Fallon
2163 West Terra Lane, O'Fallon, MO 63366. (636) 280-0990. Monday, Tuesday, and Thursday 9am to 6pm. Wednesday and Friday by appointment. Closed daily 12 to 2.
The west room runs a different week: three full days and two by appointment. If Wednesday or Friday is the only day you can get there, say so on the phone; by appointment means ask, not closed. Book O'Fallon →

The 12 to 2 closure
All three rooms close from noon to two every day. The clinic publishes this; we repeat it because it is the detail that sends people to voicemail. A 9 to 11:30 call or a 2 to 5:30 call reaches a person. If you do leave a message, leave the three things: car crash, the date, headaches since, and a number that reaches you.
Choosing between them
Most readers of this desk will pick Hazelwood. If you live south of the city, Tesson Ferry is the shorter drive. If you are in St. Charles County or further west, O'Fallon. If the drive itself is the problem, because light or fog is affecting your attention, pick whichever room someone can drive you to, and get the ride. We wrote about the week between the crash and the exam, including the car, on light and screens.
One more time, because the hours above are the clinic's and not ours: confirm them on the call. We print only what moinjuryclinic.com prints and we correct this page when the clinic changes something.
What all three rooms are for
Missouri Injury Clinic, run by Joseph L. Hollingsworth, DC, publishes three lanes: auto injuries, meaning diagnosis and a treatment plan after a crash, TBI and concussion rehab after acute injury, and sports injuries. Our readers are in the first lane, and sometimes the second. If your problem is something else, say so on the phone and let the clinic tell you yes or no before you drive.
Educational reading, not medical advice. This desk cannot examine anyone; it exists to get you in front of someone who can.
