What really makes a great coach, and what I think works so well in the PN Nutrition Certification — it’s not about telling someone to do something. It’s about knowing what questions to ask, and then leading the person in the right direction.

As I was going through the course I realized it was perfect; it’s exactly what I wanted and needed to learn. The information it taught me vs. the 4th year nutrition course I took as a Kinesiology was like comparing apples to oranges. The nutrition course was good. But the PN Nutrition Certification was that much better.

Which is better—taking the PN Nutrition Certification or going back to school?

We won’t pretend to have the perfect advice for every situation, but we do have some thoughts on this topic…

If you decided to go back to school for a nutrition degree or to become a registered dietitian, you’d likely spend anywhere from $10,000 – $20,000 USD per year. If you did a four-year degree, you’d be looking at spending upward of $40,000 – $100,000 USD.

The only problem? Most university courses lack real-world coaching opportunities. And most professors aren’t experienced coaches. That’s why many students find that they’re stuck once they graduate.

It’s also why, in the PN Nutrition Certification, we’ll share a proven coaching system that’s guaranteed to get results for anyone who comes to you for help—at a tiny fraction of the cost of attending a university.

Here’s a quick comparison…

Frequently Asked Questions

Final note

Nutrition is key when it comes to helping someone achieve their health and fitness goals—whether they want to lose fat, tone up, gain strength, feel less stressed, get better sleep, improve their mental health, or anything else.

But successful coaches realize that understanding nutrition science isn’t enough. You must also be able to effectively help others change their eating and lifestyle behaviors.

That’s what we do every day (no other nutrition certification company does this). And we’re ready to teach you the same science-based coaching method we’ve used with major health organizations, professional sports teams, Olympic athletes, and over 100,000 clients worldwide.

Of course, if now isn’t your time, we understand. We hope this helped you understand who we are and what we do. We’ll be here if and when you need us.

But if now is the time for you to build your own nutrition knowledge—or learn how to help others with their health and fitness—then the PN Nutrition Certification is everything you need to help people get sustainable results while you build a remarkable career or fulfilling side gig.

We’re excited to teach you everything we know about the science of nutrition and the art of behavior-change coaching.

But the next step is yours.

Hope to see you in the program,

– The PN Team
