Ms Yi Sia is a young and enthusiastic endocrine and general surgeon who has completed fellowships in endocrine and general surgery at Western Health and Northern Health in Melbourne.

In 2021, she relocated to Oxford, UK for a third fellowship with the Endocrine Surgical Unit at Oxford University Hospitals, under the guidance and mentorship of Mr Radu Mihai, an eminent endocrine surgeon in the UK and Europe. It was at Oxford that she developed a keen interest in thyroidectomy for large retrosternal goitres, lateral neck dissection and retroperitoneoscopic adrenalectomy.

In addition to endocrine surgery, Yi also has a keen interest in acute general surgery. She performs both elective and emergency general surgeries at a number of hospitals in the western and northern suburbs of Melbourne.
