FROM OUR FOUNDER – REED DAVIS
FROM OUR FOUNDER – REED DAVIS
Over 20 years ago, I recognized clients were caught in a “cycle of trial and error” and I committed to being the last person they needed to see. While working with top leaders in alternative medicine, I ran thousands of labs on thousands of people and learned to identify “healing opportunities.” Using all-natural, drug-free protocols I made my own observations about who got better and who didn’t, codifying which “general principles of health building” would outperform “specific treatments” being provided by standard and even alternative medicine.
And through this work I then developed the Functional Diagnostic Nutrition Certification Course and D.R.E.S.S. for Health Success
Protocol to educate and empower as many people as possible to get well and stay well naturally, so they, in turn, may empower others to do the same.

Being an FDN Practitioner allows me to help others around the world also find the missing pieces of their health puzzle so they can get back to feeling like themselves again too.

FDN gave me the confidence to implement new teachings in my business immediately, and it has helped me grow personally and professionally in so many ways. As an IIN graduate and health coach I felt I could help more individuals if I could dig deeper, and FDN has given me the tools to do that!
– Deb Pomeroy, St. Charles, IL

As an FDN practitioner’s client, I saw how quickly the approach helped me get to the root of my health issue despite doctors saying there wasn’t one. Have being a client, I knew I had to take my IIN education to the next level and become a FDN to help others like me.
