" Being a colorectal and general surgeon and cancer researcher in Sydney, my career in medicine has been driven and shaped by my passionate desire to help people, push the boundaries of medical advancements, enhance scientific knowledge and provide hope for those with critical illness.
Having the knowledge, skill and abilities to help others through critical life-threatening illnesses is a rewarding experience. The mastery of surgery and scientific research requires discipline, attention to detail, determination and altruism. It requires patience and sacrifice.
I intend to make a difference by improving the health of Australians, on both an individual and community scale, through my dedication and commitment to medicine. I have a particular interest in cancer research and teaching, and am passionate about being a well-rounded surgeon who has the knowledge, experience and clinical and technical expertise to be able to make a real impact to the lives of others." - Dr James W. T. Toh
