Allison Fitzgerald (Grech) is a paediatric Registered Dietitian with over 10 years’ experience supporting infants, children and families across a broad range of nutrition concerns. She earned her Bachelor of Science (Health), Masters of Nutrition and Dietetics, and Doctor of Philosophy (PhD) in Medicine and Health at The University of Sydney in Australia, where she lived before relocating to Toronto with her family in 2023.

Allison has extensive experience in tertiary paediatric hospitals in Australia and Canada, where she has worked across a broad range of clinical areas including general paediatrics, cardiology, respiratory, and paediatric and neonatal intensive care. She currently works at The Hospital for Sick Children (SickKids) in Toronto, where she provides nutrition care for children with inherited inborn errors of metabolism.

Allison’s doctoral research focused on maternal and infant nutrition and the gut microbiome, and the impact of COVID-19 on parenting and health behaviours. She has clinical and research interests in nutrition across the first 1,000 days of life; from conception to two years of age.

Outside of work, Allison is a mother to two busy little boys, both of whom have had their own challenges with feeding. Allison brings both professional expertise and personal experience to every family she works with, ensuring recommendations are evidence-based, practical, and aligned with their unique goals and circumstances.
