The staff is great and everyone is very pleasant. However, the treatment was largely a waste of time and unreasonably expensive. 3.5 weeks of treatment and my lower back pain had not improved at all and had possibly gotten worse.During consultation with the doctor, the target date for improvement constantly shifted: Sometimes people are completely better after 6 treatments, Sometimes people need all 20 treatments, Sometimes people need to heal for 4 weeks after the treatments, Sometimes people need to heal for a couple of months after the treatments, and finally Well, sometimes a year after the treatments people suddenly feel better.After the Maybe youll feel better in a year consultation, I was billed $2,000. Thats with insurance covering part of the cost.I would very much recommend avoiding Spinal Decompression of Oklahoma and seeking treatment elsewhere.
