Mark Holmes


Mark co-founded Circadian Australia, leads our team and draws on a successful career in international leadership to ensure that we optimise outcomes for our clients and their people. He also draws on his own recent health experiences in managing his Obstructive Sleep Apnoea, which drives his passion for helping others suffering from sleep disruption and the related health outcomes. Mark is now the first to admit that like many people he was in denial about his OSA and the toll his disrupted sleep took on his health, effectiveness and alertness.

He is now a passionate advocate of sleep disorder treatments and lifestyle changes that can deliver amazing improvements in sleep quantity, alertness, health and wellbeing.
