In a discipline where many surgeons are very clinical, and simply view their patients as a “case number”, Jason is an exception. He likes to learn about his patients – their families, their lifestyle, their hobbies, where they work – because this not only helps him to form a far more accurate picture of the individual he is treating, but it helps put his patients at ease.
Jason is a fellow of the Royal Australasian College of Surgeons and is a member of the Australian Medical Association. He is also a member of the Gastrointestinal Society of Australia and a Post Graduate of the Medical Council of Victoria. He is also a member of the OSSANZ; The Obesity Surgery Society of Australia and New Zealand.
Jason has appointments to the Medical Advisory Boards of the Western Private, and Epworth Freemason Hospitals and is a Medical Director of the Hobsons Healthcare Facilities; located in Altona, Sydenham, and Werribee.
Aside from being one of the most respected and accomplished surgeons in his field, Jason is committed to not just treating a disease, or performing a procedure.
His understanding of the sorts of emotional responses individuals can undergo when considering elective or necessary surgical procedures sets him apart from many of his contemporaries and allows him to put people at ease and give them the confidence that they have made the right decision for their health and wellbeing.
Undergoing any surgical procedure can be a very confronting, even traumatic experience for some individuals; Jason understands this and he strives to make the entire process as easy as possible for his patients, which not only helps to reduce their anxiety toward the procedure itself, but creates an immediate sense of trust between patient and doctor, a connection that is imperative when a patient is required to place their faith in a surgeon who is about to perform a complex procedure on them.
