Geoffrey Walter Edelsten (2 May 1943 – 11 June 2021) was an Australian businessman and former physician known for founding the health care company Allied Medical Group. Edelsten was a general practitioner whose unconventional clinics and luxurious lifestyle attracted media attention in the 1980s. He owned mansions, helicopters, and a fleet of Rolls-Royces and Lamborghinis with license plates such as Macho, Spunky and Sexy. His multidisciplinary clinics – the forerunners of modern corporate medical practices – were open 24 hours, and were fitted with chandeliers, grand pianos, and mink-covered examination tables.
