NUCCA, which stands for National Upper Cervical Chiropractic Association, is a specialized technique, an advanced chiropractic training, that takes into account additional information and components. From this analysis, a NUCCA trained doctor can use very little pressure to improve health, and longevity
NUCCA was developed by chiropractor Ralph Gregory in 1966 based primarily upon the work he and John Grostic had performed before Grostic's death in 1964. This new style of upper cervical adjusting technique was taught in 1966 at the first NUCCA seminar in Monroe, Michigan. Since then, there are 250 trained NUCCA doctors.
