Read biography

John Van Der Kallen FRACP is a Rheumatologist in Newcastle. John grew up in Sydney and graduated from the University of NSW. He spent time training in many rural areas of NSW as well as completing his rheumatology training in Leiden in the Netherlands where it was obvious that the community is healthier without being dependent on cars. He has lived in the Hunter for over 18 years and has seen the Hunter Valley change dramatically with the increase in coal mining. He previously set up the Fracture Liaison Service in the Hunter New England Area Health Service but is now focused on the impacts of climate change on our health. John believes that one of the solutions to climate change is for all of us to reduce our individual emissions to zero or below. Consequently, his wife Jane and himself have a timber plantation, solar panels at home and at work and commute on their bikes as much as possible.

John Iser

Member (VIC)

Read biography

John Iser MBBS FRACP retired 4 years ago after working as a physician and gastroenterologist in Melbourne’s eastern suburbs. In addition, having come from regional Victoria where “the bush” was only a bike-ride away, he gladly accepted the positions of visiting proceduralist at Alexandra and Foster for over 20 years. While at Alexandra he was attracted to the notion of restoring land which had been cleared inappropriately. However, after setting-up a sustainable cottage, the dream of land restoration might have to be fulfilled by the next generations. John joined DEA about 8 years ago and was Victorian Chair for 4 years. For decades John has been aware of the power of big business and government to brush aside environmental concerns in the interests of profits and expediency, so it is heartening to see the attitudinal shift that is now occurring. However, he believes that DEA can accelerate this change through continued engagement with all sectors and at all levels.
