We are chiropractors & researchers


We always ask, “Why do you, the practicing or future chiropractor, need to know this?”

Course Material

Course Material

We have worked hard to ensure that the course material is the absolute latest scientific material, yet seen through a practising chiropractor’s eyes. 

All course materials are referenced with reputable scientific publications, and they are discussed from the chiropractic perspective.
