Entry No. 04 / Rooms

Rooms on the ledger, and the one you can drive to.

O'Fallon serves St. Charles County; Hazelwood and Tesson Ferry serve the rest of the metro. Addresses, phones, hours, and the published patient reviews.

  • Pick the room you can reach this week. The crash location does not decide it.

Missouri Injury Clinic keeps three rooms under one name. For St. Charles County readers the answer is almost always O'Fallon, but the rule this desk keeps is simpler than geography: pick the room you can actually drive to this week. A Tuesday in Hazelwood beats a theoretical Thursday in O'Fallon. Every room runs the same published lanes, auto injuries with a diagnosis and a treatment plan, TBI and concussion rehab, and sports injuries, and every room closes from 12 to 2 each day.

Reading the hours honestly

O'Fallon is the room with the asterisk. Monday, Tuesday, and Thursday run 9 to 6. Wednesday and Friday are by appointment, which means the door is not simply open, and it also means the door is not simply shut. Call and ask. Hazelwood and Tesson Ferry run Monday through Thursday 9 to 6 and Friday 9 to 12. All three close from 12 to 2 for meetings, which is the single most common way a county reader wastes a drive. The hours here are as published on moinjuryclinic.com and are worth confirming on the phone.

The drive, county by county

From St. Charles proper, St. Peters, Cottleville, Dardenne Prairie, Wentzville, Lake St. Louis, and O'Fallon itself, West Terra Lane is the short drive, a few minutes off I-70 on the west side of the county. From Weldon Spring or the 364 corridor it is still the county's room, though a reader who works in north St. Louis County may find Hazelwood closer to the office than O'Fallon is to the house. From south of the Missouri, along I-270 or Tesson Ferry Road, the South County room is the obvious call. The crash location does not matter. Where you can get to on a weekday does.

What is the same in every room

The clinic, run by Joseph L. Hollingsworth, DC, publishes one set of lanes and one motto, putting the CARE back in Healthcare. The first visit for a crash is the same visit wherever you have it: a history, an movement and symptom examination, findings explained, and a written treatment plan before you leave. The TBI lane's named tools, vagus nerve stimulation at the tragus, neurofeedback, Alpha Stim, sensory motor integration, exercise with oxygen, oculomotor rehabilitation, and cognitive rehabilitation software, are described on the clinic's own TBI page. Ask the room you call what it offers the day you call; this desk does not publish anything the clinic has not.

Before you drive

Call first so nobody arrives at a closed door. Say it was a crash and when. Bring insurance information and what you know about the collision. If you already have an attorney, bring their contact so records can be sent where they need to go. Ask the clinic directly how a visit is billed. And remember the bright line: Chest pain, a sudden severe headache, weakness or numbness on one side, trouble speaking, a loss of bowel or bladder control, or a head injury with vomiting or worsening confusion is an emergency room trip right now, not a call to a clinic.

The one entry that matters

Get examined this week at the O'Fallon room

Say it was a crash when you call. The room is at 2163 West Terra Lane, O'Fallon. Closed daily 12 to 2.

This entry is educational and is not medical advice or a diagnosis. It is not legal advice. Only an examination by a licensed clinician can tell you what is going on with your neck, your back, or your head.

The bright line

Chest pain, a sudden severe headache, weakness or numbness on one side, trouble speaking, a loss of bowel or bladder control, or a head injury with vomiting or worsening confusion is an emergency room trip right now, not a call to a clinic. Call 911. An injury clinic is built for planned care, and a clinic that sends you to the emergency room instead of booking you is the system working.
