Cagle and Hahn are with the Oklahoma Spine Hospital http://www.oklahomaspine.com/ It is a physician-owned hospital that specializes in neuro-spinal surgery and pain management.

I don't believe they are officially affiliated with Mercy, although some of the Docs may still be able to do surgeries there.

I worked with the former management group of this hospital on some PR / Marketing campaigns some years back when they first opened. The hospital is supposed to be top-notch. I cannot speak from the view as a patient, however.
