Patient Testimonials

I saw Dr. Klopper and his staff on a Thursday afternoon, fully expecting to be scheduled for an epidural or something a little more conservative down the road. He immediately realized that my issues were more urgent than I had realized. I was in the OR the next day for surgery on my cervical spine and home on Saturday with complete relief of my pain. As a nurse myself, I was highly impressed with the staff at CNOS and the Dakota Dunes with their care!
