Dietetic Intern @ Compete Nutrition

Sarah Martel, BASc, is a graduate student and dietetic intern studying to become a Registered Dietitian through the Masters of Health Science in Nutrition Communication at Ryerson University.


Sarah completed her undergraduate degree in nutrition at the University of Guelph, where she obtained a Certified Personal Trainer certificate. She also completed a certificate in Nutrition for Sport & Performance through Niagara College where did a placement with the UofG’s campus sports dietitian.


Sarah’s passion for nutrition began after quitting competitive swimming in high school. Afterwards, her perceptions of nutrition and fitness had many ups and downs as she navigated young adulthood. Having now improved her relationship with food and exercise, she became inspired to help others do the same through her social media platforms and hopes to continue doing so as a future RD.
