I’m Dr Kate Marsh, an Advanced Accredited Practising Dietitian, Credentialled Diabetes Educator and Health & Medical Writer based in Sydney, Australia.

My goal is to help people with diabetes, women with PCOS and individuals following or wanting to adopt a plant-based diet through my work as both a healthcare professional and writer.

My interest in diabetes and nutrition began after I was diagnosed with type 1 diabetes at the age of ten, and met my first dietitian. This led me to studying dietetics and then diabetes education. Today, I combine clinical practice as a dietitian and diabetes educator with my work as a health and medical writer.

In 2015 I was awarded the inaugural ADEA National Credentialled Diabetes Educator of the Year, a reflection of my goal to make a difference to those who are living with and at risk of diabetes.

I am well supported by my long time receptionist Mette, who will be your first point of call when you contact us and can help you with any questions about my services, booking an appointment, appointment details, consultation fees and rebates.
