About Me


As a nutritionist and dietitian, my main goal is to enable my clients to not only achieve their nutrition goals but also to surpass them. Each of us has a goal that we want to achieve and constraints to get there. This is why I take great satisfaction in seeing my clients succeed and being able to guide them during this journey. In my opinion, everyone has the opportunity to have a healthy lifestyle, it’s just about wanting to put in the effort and going at their own pace.

I am a dietitian-nutritionist, professional graduate in nutrition and biological science from McGill University and the University of Montreal. I am also a member of the Professional Order of Dietitians of Quebec (OPDQ). During my consultations, I prioritize first and foremost the respect of dietary needs, based on convincing science, for the development of healthy sustainable lifestyles, while maintaining the pleasure of eating.

MCGC Nutrition is a Montreal company dedicated to contributing to the development of our community, especially during this difficult time. This is why I am particularly proud to present our new collaboration with ‘Breakfast Club of Canada’.

1 in 3 children now come to school hungry because of the pandemic. That’s why we have decided to support the cause and help those in need.

My journey

As for my studies, I obtained my bachelor’s degree in nutrition from McGill University and a bachelor’s degree in biological sciences, immunology and microbiology from the University of Montreal. I am also a member of the Professional Order of Dietitians of Quebec (OPDQ) and a member of Dietitians of Canada. In addition, I joined the Quebec Society of Arterial Hypertension (SQHA).

My major professional fields of practice are weight management, cardiovascular disease, hypertension, diabetes, sports nutrition and gastrointestinal intolerances including irritable bowel syndrome (IBS). I recently completed the official training course on the application of the “Fodmap” diet for irritable bowel syndrome from Monash University located in Australia which is the founding institution of this nutritional strategy and convincing research in this area.

Within my private clinic, MCGC Nutrition, we develop individualized nutritional strategies according to the specific needs and medical history of my clients/patients. Above all, I prioritize respecting food needs, based on convincing science, for the development of healthy, sustainable lifestyles, while maintaining the pleasure of eating.
