He has a proven record of growing organisations, both organically and through M & A. Giam is widely recognised for his leadership in the areas of innovation, culture change, and both digital and business model disruption.

As an accomplished global executive, Giam believes he can add value in supporting leaders of complex companies that are challenged with their growth strategies or are facing issues around changing existing business models. His own leadership experiences have built his deep understanding of how to lead strategically and identify effective routes to ensure that desired outcomes are achieved. He is passionate about equality in all its forms and has been recognised through a number of industry awards for diversity and inclusion.
