About Us


Dr Ammar Nagree

Ammar undertook his undergraduate medical degree at Sydney University and Westmead Hospital, followed by an internship and residency at Gosford Hospital (NSW). He did his Basic Physician Training at Royal Hobart Hospital (TAS) followed by Advanced Training in Gastroenterology and Hepatology at the Prince of Wales Hospital (NSW).

Upon completion of his specialist training he worked in Tanzania for 10 months, training local staff in Gastroenterology, Hepatology and Endoscopy. This was followed by 18 months of post fellowship training at the Royal Free Hospital, London, well recognized as an international centre of excellence in Hepatology. Following this he completed a further 18 months at St Mark's Hospital, London, which is a leader in Gastroenterology and Endoscopy services.

He is now based mainly in Rockingham/Waikiki (40 minutes south of Perth, WA), consulting as a general Gastroenterologist and Hepatologist at the Waikiki Specialist Centre and performing endoscopic procedures at Waikiki Private Hospital. He has also started to consult at the Wexford Medical Centre (Murdoch) once a fortnight and perform endoscopic procedures at St John of God Hospital (Murdoch) on a Saturday, ideal for busy working people who find it difficult to take time off work during the week.

He is currently consulting and performing endoscopic procedures at St John of God Hospital (Subiaco) and the GI clinic (Myaree) and is doing research work in Inflammatory Bowel Disease with Professor Ian Lawrance.

Shanela is actively involved in research and international conference presentations both in general gastroenterology and inflammatory bowel disease.

Dietician Services

Ms Caitlin Schipp

I am a passionate dietitian who enjoys working closely with people to improve their general health and wellbeing, and those with more specific medical concerns requiring nutritional support.

I am now excited to be part of Dr Nagree's practice as I have a strong interest in gut health and will be consulting at the Waikiki Specialist Centre.

My interest in gut health and nutrition was sparked at a young age when my sister and father were diagnosed with coeliac disease, requiring a strict gluten free diet.This first hand experience has given me an in-depth understanding of the impact that diet can have on everyday life.

I currently work as part of a holistic multi-disciplinary team at the Thrive Wellness Centre (Ascot) and volunteer at the Better Health Program.
