Greg Hitchen, Group Chief Executive, Terrapinn

Greg Hitchen  

In my roles at Terrapinn, I have been privileged to create and develop many of our global event brands. And in developing many people who have become leaders at Terrapinn and across the events industry. I have enjoyed working directly in Australia, Asia, Africa, the Middle East, Europe, the USA, and Latin America in a 35-year career.

I am highly focused on growing Terrapinn’s business, which is increasingly about acquisitions. My current passion project is MOVE, our mobility event series.

Events is a highly rewarding and dynamic career, and Terrapinn is a wonderful, creative, and merit-based company. My career is a testimony to the opportunities available to all.
