Team executive medicine

Dr John Cummins MBBS, MPH (USA), FRACP

Consultant Physician, CEO and Practice Principal at Executive Medicine

Completing his medical degree in 1984, Dr Cummins was inducted into the prestigious Royal Australian College of Physicians in 1992 and trained for a further 2 years 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. He commenced a search for the perfect wellness and preventative practice, giving his people the optimal chance of thriving and surviving based on the lifestyle practices of the longest living race known to man such as the Okinawans and the Sardinians.
