“It’s definitely worth the money. Worth every penny. Best investment you can make, both for your clients and for people in your life. I think all health coaches should go through this."

Margie Bissinger, MS, PT, CHC, CFNC

“I have learned more than I ever could have imagined. These teachings and this community have provided resources and guidance far beyond my expectations. Going through Full Body Systems has allowed me to see possibility and feel confidence in taking care of clients who previously seemed overwhelming." 

Stacy Day, BSN, RN, CH, CFNC

“I have been through several other courses with either a focus on lab work or an eye to functional methodologies. FBS was by far the richest in content, learning, support, accountability, and freshness. Now that I’ve been through FBS I have so much more to offer my clients and a whole new way of really engaging them in their wellness journey. If you are thinking about FBS, just do it. You won’t regret a moment.”

Crissy Luna, CIHC, INHC, CFNC

“I have taken several holistic nutrition programs over the years and none of the programs compare to Full Body Systems. This is the best nutrition training and it’s a must for all healthcare practitioners including doctors, dietitians, and nutritionists.”

Esi House, CFNC

“Coming from a conventional nursing background, I found that although I intuitively knew that treating symptoms wasn’t really addressing people’s health, I didn’t know why or how. Full Body Systems has taught me the anatomy and physiology that explains “what’s going on in there” in a way that I didn’t learn from my nursing education.”

Jennifer Nathanson, NP, CFNC
