W.H.
S., My husband had been seeing him for a couple of years. Lots of money, time and he seems a bit better, but will always occasionally need an adjustment for his back problems. My husband, had been seeing Chiropracotors for years prior to seeing Rider. Never on quite an intense plan like Rider's though.
I had also gone through the diagnostic work up with them. They presented me with the same expectation of me doing an 18 month program. I don't have back issues, but preventative maintenance that he stated I needed. No Thanks! The quality of my life is fine with out the treatments and costs.
If you truly have some issues then Dr Rider, Lisa his wife and staff will treat you well. Just don't be led down the path with their theory, if you really don't need it.
Looks like you have gotten plenty of advise and will have to make a personal choice. Good Luck! W. H
