The NUCCA spinal corrective procedure is based on measurable and tested procedures that have been developed starting with the work of Dr Ralph R.Gregory and Dr John F. Grostic in their collaboration between 1941 and 1946.   

As Dr Gregory founded the NUCCA organization in 1966, he wanted an organization that was founded on tested and proven principles and procedures.  The Board of Directors created an organization designed to be tested, advanced and refined.  Due to the great complexity of the Atlas Subluation Complex, and its detrimental effects on the health and physiology of patients, Dr. Gregory started the Board Certification Program.  This program was initially a testing program that allowed doctors to advance their level of skill in the understanding and reduction of the ASC.  In the late 90’s Dr Marshall Dickholtz Jr. worked to develop the program into a testing and mentoring program which continues to be refined today.  The program is the foundation of NUCCA’s educational process.   

While all members who practice the NUCCA procedures are encouraged to be actively engaged in their ongoing learning and development, the program is voluntary.  In order to assist the public in finding help we have developed a Locate a Doctor Function that endeavors to explain what the different competencies achieved by the membership mean.  In any procedure where the complexity is high and skillsets are individual, it can be challenging to understand what is meant by a group and their trade’s venacular.  With that in mind, our goal is to make finding a qualified practitioner simple.

How to use the NUCCA Doctor Directory:

Depending on a patients location, access to levels of education and experience among practitioners can vary. While our organization is continually working to create more highly skilled practitioners, we suggest using this directory to help patients find the most qualified doctors.  The capacity of a patients recovery and physiological alteration can depend largely on the training received.
