I’m Tina — a Registered Dietitian, Certified Specialist in Sports Dietetics (CSSD), Certified Strength and Conditioning Specialist (CSCS), and Tactical Strength and Conditioning Facilitator (TSAC-F) with five years of applied nutrition experience.
My background spans performance nutrition coaching, military nutrition (currently an active-duty dietitian), research, eating disorder treatment, and long-term care, giving me a depth of knowledge I’m ready to use to help you reach your goals.
I founded Tina Sergi Nutrition, LLC to help female Olympic Weightlifters fuel for performance in a way that fits their life and doesn’t feel like a second job.

Between years of dance, gymnastics, CrossFit, and Olympic weightlifting, I know what it feels like to train hard and wonder why your body isn’t responding the way you expect.
Like many others, I also spent years under-fueling, obsessively tracking, and following diets that weren’t built for performance – or for my long-term health. That firsthand experience is what drives me to coach my athletes differently – with a plan that supports your PRs and your health for the long run.


While nutrition, performance, and health are important to me, I understand that athletes like me need time for fun.
In my free time, I like to read, go to the beach, pick sunflowers, spend time with my dogs, and I have a newfound love for Marvel movies!
