“Dr. Donald Epstein has accomplished incredible intellectual feats related to understanding the role of the nervous system in the human experience. His model of spinal-neural integrity has led to open doors where previous models of subluxation left me at a dead end with no where to go to expand my understanding. His genius completes much of the puzzle that our chiropractic ancestors started putting together long ago. No matter what your background or orientation, any chiropractor would benefit by being exposed to both his concepts and his hands.”
