What people are saying

Elissa C.

I have loved FDN and what it has done for my own health. I can only imagine how I am going to be able to help so many people with this. I appreciate that there is a whole team of people working together to make this the best information possible. It seems as there are many influences including MDs, NDs, and the FDN mentors that all contribute to making the information up to date as well as providing support.

I have learned so much in my FDN program. I am already a certified Nutritional Therapy Practitioner and CHEK Holistic Lifestyle Coach II, but I already know this program definitely took me to the next level of practice.

I loved the FDN program. I have been plagued with health symptoms for many years. I decided to embark on this program because I was tired of going to western medicine and naturopathic doctors and they continued to treat symptoms instead of the underlying problem. The FDN program was so much more than I anticipated. My mentor, Ann, was wonderful. The Facebook page and Friday calls give some much more additional needed information. Thank you for providing both of those.

I loved the FDN class and I’m so excited to graduate so I can start helping people with those problems that no one else can seem to figure out. Reed’s passion comes through in each and every lesson. I liked the structure of the course. Watching the videos was great for me. I liked the immersion experience and having the chance to do an R&R meeting with my mentor and get feedback. My mentor was also really understanding about my schedule and tried to accommodate me to help me reach my goal of completing the course in a certain timeframe. Overall I can’t be any happier that I have decided to pursue my passion with FDN.

First, I want to say that FDN has changed my life. When I started this program over a year ago, I was practically non-functional due to years of chronic stress followed by one VERY acutely stressful job lasting about 3 1/2 months. Using the DRESS protocols and my dream of helping people heal from chronic stress-related issues using FDN, I transformed my life and my health with the guidance of my mentor Julie. The information provided is quite in-depth and yet still understandable for me as a non-licensed practitioner. It is both accessible and scientific enough to allow me to feel like I know what I’m talking about when I share what I’m learning. The organization of the webinars is intuitive and follows a clear path. Overall, there is a wealth of information and resources available to me as a student/trainee. The availability of a mentor for the duration of my training and a personal protocol was/is an invaluable resource.
