Meet the Nutriology Team

The world of wellness is a noisy place. And let’s be honest – not every “guru” has your best interests at heart or the credentials and experience that you deserve.

Nutriology is different. Which means your results can be different. And it starts, if you’ll forgive our pun…at the core.

Nutriology’s team of experts curates an effective and sustainable plan for each member,  which means that you get the benefit of the best information on the market with simple, actionable strategies that fit into your busy life and lifestyle.

These experts include registered dietitians, certified trainers, credentialed wellness experts, member success managers, product designers, tech developers, and more. 

Our team is 100% committed to your success, from Day 1. Meet some of the Nutriology team members who will be guiding you through your health and wellness journey.

The Team

John Chesley

Founder and CEO

I founded Nutriology because I believe that each one of us – regardless of our age, or our circumstances – deserves the opportunity to enjoy our meal time experience, develop our fitness confidence with safe and effective workouts, and live our best life.

And because frankly, I didn’t see any programs on the market that fit my needs.

Here’s the deal…I’m not a personal trainer. Or a registered dietitian. Or a master health coach. (I’ve simply surrounded myself with some of the best in the business, as you’ll see below!)

I’m a business owner, with a background in brand development and finance. I’m a husband and a father. And I, like you, have tried all of the wellness and weight loss strategies out there. I have waded through tons of information and recommendations, both good and bad, and I realize the source is a distinguishing element.

As you begin your Nutriology journey, I will be right beside you, cheering you on and also listening to your feedback. My commitment to you is that if you invest in yourself, and in Nutriology, you will always have access to me, whether it’s in the role of Nutriology founder, or in the role of Nutriology member. (Because, yes, I really do follow my own program.)

I would like to introduce you to the incredible team of wellness and tech experts who not only contribute to the program but who are highly trained, experienced and passionate individuals who will make sure that you finally experience the lifestyle change you’re looking for.
