What I Am Passionate About

Having suffered from food intolerances and digestive issues in my younger years, I developed a keen interest in nutrition. I found nutrition fascinating and truly believe in the benefits of nourishing our bodies with the right foods.  

I strongly believe that there is no one size fits all approach when it comes to nutrition. This translates to the way I work with my clients. I will never ask you to go on a popular fad diet for a quick fix or hand you a generic information sheet. At SDC, we focus on offering a premium service where you can expect individualised care under a trusted, experienced practitioner. As a university qualified dietitian, I am committed to providing evidence-based nutrition advice that you can trust. I will take the time to work with you to understand your health needs and ensure you feel 100% supported throughout the entire process. 

I am super passionate about gut health and feel very fortunate to be working in an area I love, helping those who are going through health issues I once experienced. It brings me so much joy to see  lives transformed when my clients learn how to gain control of their symptoms and enjoy food again. This inspired me to develop the FODMAP Focus Program, a structured, comprehensive program that supports clients through the 3 phases of the low FODMAP diet. This program is available to clients all around the world.

I would love to help you, get in touch to work with me.
