From Curls & Cleats to Higher Performance.
I grew up in Nashville (Yep, I’m a unicorn as they say) home of Fried Chicken and Goo Goo Clusters. It was not unusual to have homemade Buttermilk Biscuits with Chocolate Gravy for breakfast. Sports and performance have been a part of my life from as long as I can remember. This pic is me at about 6 years old. Already in cleats (and curls, of course).
Along the way, I’ve worked with NFL, NHL, and PGA athletes, Division I competitors, executives, and artists—and I’ve spoken for organizations like KPMG, LBMC, Belmont University, and many others. But at the end of the day, what matters most to me is helping you build a healthier relationship with food, performance, and yourself.
I’m the author of The Metabolic Makeover, Limitless, and Your Unique Fizeek!: A Girl’s Guide to Faith, Fuel, and Finding Your Superpowers (a USA Today Best Seller in 2025). I also hosted the podcast Fuel, Sweat, & Science with Dr. Tiff, where I shared research-backed strategies to help people fuel their bodies and unlock their potential.
When I’m not coaching, teaching, or speaking, you’ll probably find me on the hunt for Nashville’s best sno cones or hanging out with my Cocker Spaniel, Tucker, who keeps life fun and a little chaotic.
Decades of Dedication
I have spent over two decades developing what I believe to be the MOST successful, and sustainable approach to creating a lifestyle of health and performance. The SCIENCE of understanding how your body uses Food as FUEL, and turns SWEAT into the body you have worked so hard for. Once I had mastered this for myself, I knew I had to bring that same foundation of scientific principles to all of the rest of you.
I'd love to meet you!
Give me a call and let's talk about your challenges and fitness goals.
