"As a healthcare provider "in the know" about advanced nutrition principles and functional medicine I thought I knew everything I needed to about celiac disease and non-celiac gluten sensitivity. Boy was I wrong! After reading Nadine's book and attending her speaking events I am convinced I have only scratched the surface. She has truly provided a much needed resource to people from all walks of life to understand their condition and how to live a healthier lifestyle. I am so grateful she is available in our community to educate others on this subject."
