Diagnosed at 20 with rheumatoid arthritis, she could no longer work at 30.

"By the time I quit working, I hurt all the time. It took me forever to get out of bed and the rest of my day was a struggle to do anything, starting with brushing my teeth. I had the life quality of a blob."

Linda's pre-treatment x-rays showed scoliosis. Three weeks into care, she had her first complete night of sleep in 18 years. Fourteen months after starting The Pettibon System, Linda began shopping, cleaning, and cooking. "I treasure being able to do these mundane activities," says Linda. "The Pettibon System has given me back my life."

Functional Nutrition

Course Description

Functional Nutrition covers labs, immune system, brain function, blood lipids, endocrine system, digestion system and lifestyle habits (poor and great). This course will help and assist practitioners to be more equipped to evaluate each unique patient from a lab work and systems approach. These procedures are a great foundation for full body systems review. Some patients may need further testing outside of these procedures; however, these procedures are initially designed to guide practitioners into the proper diagnosis or guide them into further advanced testing. Once the proper diagnosis has been attained then nutrient recommendation guides are provided for exposing the practitioner to the world of nutrition.

This class is for practitioners to introduce, revitalize and renew their sense of importance for the nutritional and lab evaluations of a patient. Practitioners educate many of their patients on nutrition and lifestyle changes; however, very few of them truly analyze or evaluate what the patients needs are (on the inside as well as lifestyle). Documentation of the lab analysis and the nutritional evaluation, what is seen, preformed and tested, is an important key that one cannot miss. One cannot prove, disprove or improve that which he cannot measure. By reviewing the multiple systems from a nutritional and lifestyle approach, measuring it and putting together how it connects with other areas of the body, how each system interrelates and what other tests might be needed we can properly arrive at the precise problem(s). We use patient’s objective measures through our testing to understand each patient’s condition completely and comprehensively in order to properly diagnose. From the diagnosis we can then start formulating a plan on whether or not we can help this patient. The communication to each patient during the education processes, in regards to their health problem(s), labs, nutrient deficiencies and their nerve system, is crucial and can make the patient want services or reject services. Our primary goal is for each attendee to gain the appreciation for analyzing labs, nutrient deficiencies and lifestyle problems. Most importantly our goal would be to help show how to measure them!

Time to Complete

The clock starts running as soon as you register. You'll have 30 days to complete the course. If you are not able to complete the course within those 30 days, contact us at to request one free course extension (30 days). There will be a $20 fee for each additional 30-day extension.

What's the process for getting CE hours?

We send a monthly report of doctors who have successfully completed the online courses to the coordinator at Palmer College and PACE (Providers of Approved Continuing Education) at the Federation of Chiropractic Licensing Boards at the beginning of each month. The doctors' chiropractic regulatory boards are then informed by the CE providers. Not all boards accept online courses for CE hours and not all boards accept courses from Recognized PACE Providers. We have listed all the CE Re-licensure Requirements for the US and Canada so you can verify what your board accepts.  Hours in this report are calculated based on time spent to complete a course up to the amount available.

Some states and provinces require the doctor to submit the certificate of completion. It is your responsibility to know the process with your state/province. If you are responsible for submitting your hours, be sure to print out the certificate once you finish the evaluation at the end of each online course.

(Need assistance in a hurry outside of the monthly report? E-mail for assistance, there will be a $25 filing fee.)
