Welcome to Coastal Gastroenterology

Coastal Gastroenterology was established in 2013. Our practice aims to provide a high quality and timely service for GPs and patients for investigation and management of a broad range of digestive and hepatobiliary disorders.

We provide consultation services at the Wexford Medical Centre in Murdoch and Central Specialist Centre in West Leederville. We can also provide Telehealth follow up appointments for our regional patients.

Challenges are what make life interesting and overcoming them is what makes life meaningful.


Our Doctors provide open access ‘no gap’ endoscopic services at St John of God Murdoch, Bunbury Day Hospital and Hollywood Private Hospital Nedlands.

As a patient of Coastal Gastroenterology, you will be provided with a friendly and proficient service for your medical consultations and endoscopic procedures. As part of your initial and ongoing care, you can be assured of confidentiality, an understanding of the outcome of your consultation or procedure and continued follow up care by your specialist where required.

You will also have the opportunity to provide feedback via our Patient Satisfaction Survey about your experience so that we can continue to improve our service.
