Julia Celestini

Verified registered dietitian. Our team has personally checked the credentials of this dietitian.

Oakville, Ontario


Julia completed her dietetic internship program at SickKids hospital, where she learned from world-renowned experts of pediatric health & nutrition. Julia witnessed first-hand how nutritional interventions have the potential to improve health outcomes and change lives. During her internship, Julia developed a passion for nutrition support in gastrointestinal conditions. After completing her internship, Julia returned to SickKids to work with the incredible patients, families and interprofessional team as a clinical dietitian with the liver and small bowel transplant team and currently works within the Group for Intestinal Treatment and Function (GIFT) team.

Outside of the clinical world, Julia realized there was a gap in evidence-based, individualized nutrition support in her community. In 2019, Julia opened her private nutrition practice in Burlington. Through her work in private practice, she quickly found her passion for supporting children with digestive health conditions in the community.

Julia is trained in the low FODMAP diet for irritable bowel syndrome through Monash University and she supports pediatric clients with growth difficulty and gastrointestinal concerns (including irritable bowel syndrome, inflammatory bowel disease, food protein-induced enterocolitis syndrome (FPIES), food allergies, constipation, diarrhea and reflux).

In 2021, Julia expanded her private practice by opening Happy Bellies Nutrition. She is now joined by 2 incredible dietitians and together they provide excellent nutrition care for children and families across Ontario.

Julia’s mission is to help children and teens take control of their digestive troubles, form positive relationships with food and lead happy lives.

1:1 nutrition support is available from the Happy Bellies Team for all ages and services are 100% virtual. 1:1 counselling is available for Ontario, New Brunswick, Nova Scotia and New Foundland and Labrador.
