Mark Oostergo

Principal Psychologist

Mark has an unique blend of proven experience and expertise in mental health and a deep understanding of how organisations can create systemic change to create healthy and successful workplaces.

Mark has a broad background, beginning his career serving nearly a decade in the Australian Army as a Psychology Officer. This provided him the opportunity to provide individual, team, and Organisational Psychological intervention both in Australia and overseas on operations.

During this time, Mark also had the privilege of working with Australia’s elite Special Forces in human performance, workplace mental health, and selection and assessment. Mark concluded his career in the Australian Army as the commander of a health centre with over a hundred staff across multiple professions. He was awarded an Australian Defence Force Gold Commendation for his motivational and supportive leadership in this role.

As a psychologist, facilitator and coach, Mark has worked across industry in human factors, human performance, workplace mental health strategy development, psychosocial risk assessment and management, and leadership development.

He is passionate about providing solutions that impact 5 in5 employees, not just the 1 in 5 who may experience mental ill-health at anyone time.

Mark has applied these skills across industry including professional sports (Western Force Rugby and NRL), police and emergency service agencies at the state and federal level, mining and resources, professional services, and finance and insurance.

Mark has helped countless senior executives find the best versions of them so that they lead through wellbeing.
