Our leadership

We believe leadership is not just about a title, for us it’s about collaboration and inspiration.

We foster a culture of leading by example, inspiring and engaging others to empower our people to reach their full potential and in turn contribute to collective goals.

Our Executive Committee spans five countries while our global team of circa 13,000 employees is spread across 100 offices worldwide. We don’t add up years spent in the industry as a measurement of success or leadership qualities, we simply look to recruit the best talent and put the right people in the right positions to deliver the diverse mix of skillsets required to drive our business forward.
