Upon completing NeuroGastroenterology fellowships, Dr Kellar co-founded the QLD Pelvic Floor Centre, and established the Royal Brisbane and Women’s Hospital NeuroGastroenterology service where she leads a specialist multidisciplinary team.

Dr Kellar is a passionate clinician-researcher and member of national and international working groups. She currently sits on the Gastroenterological Society of Australia (GESA) Luminal Faculty Committee, and the GESA Education Committee. Dr Kellar led the Australian working group for the assessment and management of idiopathic gastroparesis in 2025. She is an active member of the key NeuroGastroenterology societies including ANGMA, ESNM, and the Rome Foundation (see: https://theromefoundation.org/what-is-a-disorder-of-gut-brain-interaction-dgbi/). Her key research areas include chronic nausea syndromes, gastro-psychology, and the overlap between eating disorders, motility disorders and disorders of gut-brain interaction.

Dr Kellar performs high resolution oesophageal manometry and pH-impedance testing from her Chermside rooms (contact https://mgisb.com.au/), for the assessment and pre-surgical work-up of swallowing difficulties (dysphagia) and reflux (GORD).

Here at QPFC, Dr Kellar provides collaborative, judgment-free care, working together with select GI dietitians, pelvic floor physiotherapists, and mental health clinicians as needed to improve the symptoms and quality of life of people living with chronic gut symptoms. Dr Kellar believes that listening and empowering her patients to understand their symptoms is the foundation for recovery. A clear diagnosis, supportive education, and flexible management plan are essential.

Dr Kellar performs rapid access upper GI endoscopy and colonoscopy from the updated North West Private Hospital in Everton Park, with wait times typically under 4 weeks. Patients can be referred via the link at the top of this page.

*Please note for all new referrals*

Currently limited capacity for new complex consultations – Dr Kellar can be contacted directly by your doctor to discuss urgent cases.

Patients requiring artificial nutrition support, via enteral tube feeding or parenteral nutrition, are not seen at QPFC as this requires tertiary public hospital multidisciplinary care. Please see your doctor for referral to Dr Kellar’s NeuroGastroenterology Clinic at the Royal Brisbane and Women’s Hospital if within Metro North catchment, or the equivalent service at Princess Alexandra Hospital for Metro South catchment.
