Who is OrthoMO?

OrthoMissouri (or OrthoMO for short) is a musculoskeletal practice featuring six physicians and a friendly, seasoned staff to meet your needs.

Ortho + MO > The Greek root for orthos means “straight and upright.”
> MO is the abbreviation for Missouri, which differentiates it
from other “M” states.

Why does this matter? It’s because we aim for “straight and upright” as it applies to both our patients and our practice. Patients want to return to their best life and as a practice, we promise straight talk. We will intently listen to you and keep all lines of communication open, every step of the way. We know that efficient service makes all the difference, so we promise to promptly take care of you. Just as the abbreviation of MO differentiates it from other states, we aim to distinguish our practice with our prompt attention.

What you can expect

Your best life is our goal. It’s that simple.

We have great confidence in the training and experience of our physicians. We trust our friendly and very capable staff to see you and hear you. New technology is always a bonus. And convenience! We do our best to provide for all your musculoskeletal needs under one roof (and if that’s not possible, we are on the phone to find the most suitable option for you). All of these are important and necessary to your experience. But equally important is our promise to promptly address your needs so you can return to your best life.
