My Name is Dr Lt Sagi Kalev,
My Name is Dr Lt Sagi Kalev and FDN is truly one off a KIND!!!! FDN -P was and after 14 years is still my to go to program. I joined FDN on Mr Reed Davis second class and from the start I knew that Mr Reed didn't create the course for the money but only to make health provider's like myself BETTER!!! As a Veteran my word is my VALOR and no matter if you are an MD- DO-ND- NMD- NP- PA extra you will be amazed how your outlook at healing and helping your patient's :)... You will be their Hero for a life time. I have Graduated from 3 Universities..on top of IFM- A4M- UFM,,,, EVERY single time I get asked " how are you so well rounded and what did you do to get there?... FDN program is a NO Brainer.
Response from Functional Diagnostic NutritionNov 25, 2025
Dr. Kalev, we are incredibly honored by your words and your service. To hear that FDN remains your "go-to" foundation after 14 years—and alongside such impressive credentials—is exactly why Reed started this mission. Thank you for being such a valued part of our history and community!

No Regrets!
From the first module I listened and learned from I knew this was the right place for me! As a health and wellness coach I wanted a way to offer testing for my clients! Learning that testing and not guessing is the motto at FDN! I not only learned the the why but the why and what to do for my clients! Quality thru and thru from the material, to the support and the likeminded people I met. Get started today, you won’t regret it for a second!

Certification Far Exceeded My Expectations Plus Continued Education Opportunities
The FDN Certification was everything I didn't know I needed. I set out to get a certification to further my work as a practitioner and I got so much more than I could have imagined, including a supportive community, continuous learning opportunities, and the knowledge and tools to truly make a difference in the lives of others on their health rebuilding journeys. I would recommend FDN time and time again to those who are looking to get into or further their career in the health space.

"Everything I didn't know I needed" is such a wonderful compliment! We’re thrilled that the community and ongoing education have been just as valuable to you as the core curriculum. Thank you for recommending us to future practitioners—we’re lucky to have you with us!
