Dr John Cummins MBBS, MPH (USA), FRACP

Consultant Physician, CEO and Practice Principal at Executive Medicine

Completing his medical degree in 1984, Dr Cummins completed a further seven years of advanced physicians training and was inducted into the prestigious Royal Australian College of Physicians in 1992, followed by a further two years study in Minneapolis, USA, completing his Masters in Public Health and a Fellowship in Adolescent Medicine.

Whilst successfully training to be an expert diagnostician, John has always found it tragic that people are diagnosed with a terminal illness that could have been entirely prevented or even cured if diagnosed at an earlier stage.
