I grew up inside the world of elite sports performance. My father, Mackie Shilstone, spent 43 years working with over 3,000 professional athletes — Serena Williams, Michael Spinks, Peyton Manning, the San Francisco Giants, and many more. The methods that produced those results were built on real science. I watched that up close my entire life.

Our family operated nine GNC franchise locations for 26 years before selling in 2022. Working inside the supplement industry at that level — and holding four NASM certifications — I kept seeing the same pattern: people buying products and following programs that didn't reflect what the research actually showed, and seeing the results they wanted.

Since then, I've spent three years teaching New Orleans about the latest health and wellness research as an on-air contributor for WWL-TV (CBS). I've worked with individual members of U.S. Army Special Operations Command to build custom recovery and performance programs. And I've helped people navigating GLP-1 medications protect their muscle mass and maintain their VO2 max — because losing weight and losing health are not the same thing.

MaxWell Nutrition is the platform I built so that the same standard of science-backed coaching is available to anyone who's done renting their health and ready to own it.
