Jillian is an Accredited Practising Dietitian (APD) with the Dietitians Australia (DA).  

She is an Associate Member of the Australasian Society of Clinical Immunology and Allergy (ASCIA) and proud to be affiliated with the Compass Immunology Clinic in Brisbane.

Jillian is a mother of three children with over 20 years experience as a Clinical Dietitian and Nutritionist.  Her passion is providing practical strategies to improve nutrition related issues:

  • based on best practice healthcare guidelines

  • tailored to individual circumstances

Jillian understands that meal times are not straight forward for many children and families. With differing information available online, in the media and within our social networks, it is often difficult for parents to follow a single plan with confidence.  Jillian's approach is genuine and caring and without judgement.
