Our story

Supported by the New Zealand Dermatological Society (NZDSI), DermNet was launched in 1996 by dermatologists Dr Amanda Oakley, Dr Mark Duffill and Dr Marius Rademaker.

Over his career, Dr Mark Duffill had collected and classified a large collection of Kodachrome clinical photographs and patient-friendly information leaflets on wide-ranging dermatological conditions. He shared these freely with his colleagues, for their education and for the benefit of their patients. In 1987, Dr Amanda Oakley joined Dr Mark Duffill in the Waikato public dermatology service, with Dr Marius Rademaker following later, in 1992.

These three dermatologists founded DermNet in 1996, forming the DermNet Development Group. Mark’s clinical photographs and patient information sheets were the cornerstone from which the website was created. Dr Amanda Oakley showed great prescience in digitalising and publishing vast numbers of images and topic pages which over the subsequent years grew to what it is today.

Since its humble beginnings, innumerable patients have willingly gifted images, hundreds of writers have written and researched content, and countless hours have been volunteered to build the world’s leading free dermatology resource. To all the contributors, we are very grateful.

Dr Amanda Oakley was appointed as a Companion of the New Zealand Order of Merit for services to dermatology in 2018. Amanda stepped down as Editor-in-Chief in 2020. DermNet then welcomed Dr Delwyn Dyall-Smith as Editor-in-Chief who worked above and beyond expectations to help DermNet through a challenging transition. In late 2021, UK dermatologist, Dr Ian Coulson was appointed as Editor-in-Chief, and DermNet continues to go from strength to strength under his Editorial leadership.
