Did You Know?

We have been training health coaches longer than any other program? Check out our origin story here: 

The Perfect Complement™ to Medical Treatment

If you have a serious medical diagnosis or are under the care of a physician for medical treatment, you can still come to us for help. Our general principles of natural health-building serve as a grounding program during any medical crisis, and can often reduce the need for medication and surgery.  

FDN® is considered by many physicians to be the Perfect Complement™ to evidence-based medicine.




“As long as the progress of the stress cascade is not so compressed that our observations cannot be capitalized on, our method will always improve the health of our clients” ~ Reed

It's time to take care of you!

Whether tending to the needs of loved ones or achieving professional goals, it’s difficult to put forth your best effort when you’re exhausted and overwhelmed. Chronic issues–digestive, hormonal, or glandular—can leave you feeling discouraged and incapable, and even negatively impact the way you look.


Our FDNthrive® practitioners have seen it all. We know that dysfunction comes from imbalance, and we have the tools to teach you how to reverse most of your symptoms. And once you’ve achieved natural, sustainable wellness and feel and look your best, you can focus on the people and things around you with new energy and clarity.
