About Me


I’m extremely passionate about evidence-based nutrition and dietetics, and the use of clinical reasoning to provide safe, practical and quality patient-centred care.

In my work with clients, my approach to the assessment and treatment is always personalised and holistic, paying particular attention not only to the client’s diet, but also their lifestyle including their mental health and current stress levels, their physical activity and quality of sleep.
As well as extensive experience in supporting clients with a range of gastrointestinal conditions I’m passionate about women’s health and the role of nutrition in fertility (male and female).
