Dennis is a contributor to discussions on the topics of leadership, ethics and organisational purpose.


Few whistleblowers get to tell their tale to receptive audiences and to grow and learn from the experience. Dennis Gentilin has, not by blaming others, claiming heroic status or reliving the events, but by placing his experience into a broader perspective that draws on research and practical implications for leaders. His writings and talking about ethical failure provide practical guidance for all leaders and questions why and how otherwise good people behave badly.

Dennis was an engaging keynote speaker and panelist at a recent CAANZ event on business ethics. His personal experience coupled with his research in the area made his insights and contribution invaluable. What is most impressive about Dennis is that he has reflected on his experience in such a way that it does not narrowly or negatively define him, but rather allows him to share the compelling lessons associated with it in a powerful way.

Dennis did an outstanding in-house presentation to senior representatives of Australian superannuation funds on how ethical failures come about and how they can be avoided. I appreciate Dennis’ contribution to ACSI’s work on ethical culture and whistleblowing as well as his contribution to the public debate on this important topic.

Louise Davidson, CEO, Australian Council of Superannuation Investors (ACSI)


Dennis possesses a deep academic intellect and interest in business ethics, combined with extensive leadership and change management experience in the corporate sector. This unique blend of skills, competencies and capabilities makes Dennis an engaging and authentic keynote speaker who inspires enthusiasm, reflection and humility through an allocentric view.
