Jenner has been an Australian newspaper and magazine cartoonist for over twenty years, drawing professionally and non-professionally in both the Australian and US scene in the small amount of time outside his duties as a full-time doctor. He is currently working in a city general practice, and has adopted the anonymous pen name Jenner as an ethical courtesy. Although a daily strip on the Internet is four years old, his Doc Rat character has been appearing in medical and non-medical magazines for over a decade, including Bush Alert, vicdoc and the Medical Journal of Australia. Jenner currently editorial cartoonist for Australian Doctor Weekly.
