Sports, Running, & Triathlete Dietitian Nutritionist

How many times have you second guessed yourself about your nutrition as a runner or triathlete due to information overload? Maybe you’ve sized up your competition on the starting line questioning your own body size?

I remember it like it was yesterday. I was in junior high school at the regional cross country meet. I requested a small t-shirt size for pre-race pick up and was denied because those shirts were being saved for the ‘smaller girls’. My friend and I even joked that we were considered the ‘big girls’, but deep down inside, I know we both felt our insecurities bubbling to the surface when we stepped on to the starting line the next day. This was just the beginning.

From eyeing up body size of competitors, to coaches that emphasized backing off the snacks, and teammates that would only eat lettuce after doing a 20 mile run, it all influenced my trajectory in the sports nutrition world.

I’m on a mission. A mission to separate facts from fads. To change the message in the endurance community from ‘skinnier is better’ to one that celebrates the health and performance no matter the body size.

Fueling doesn’t have to be complicated. As a sports, running, and triathlete dietitian, I help endurance athletes shift their mindset to create an athlete nutrition program that will help them achieve their performance-related goals through my Fly Higher nutrition coaching process!

Sports & Endurance Dietitian Nutritionist

From being raised in a Portuguese household to participating in countless softball tournaments, I grew up in a space where food was celebrated and shared among family and friends. After discovering the nutrition and dietetics career path, I became a dietitian nutritionist to help others find the same joy in food and movement.

After my softball days, I geared my own athletic path towards triathlon, trail running, and ultramarathons. During this time, I witnessed fellow endurance athletes struggle with their relationship with food, fueling, and body image.

Using my combined training in eating disorders, Intuitive Eating, and sports nutrition, I’ve made it my mission to guide endurance athletes towards their goals. Using a weight-neutral and anti-diet lens, we work together to create an athlete nutrition program that meets each endurance athlete’s specific nutritional needs while helping them achieve their goals. 

My nutrition philosophy is that food is fuel – but food is also for joy, pleasure, and celebration. Food choices and exercise abilities hold no moral value. All bodies are good bodies, no matter the size, and you deserve nourishment, self-care, and permission to exist in the endurance sports space!
