This should not be at the cost of people's work-life balance, and he constantly drives a 'work smarter, not harder' approach with people and processes. He constantly reminds the team that everything they do is about adding value for clients, and if it's not adding value, then why are they doing it?

"I love bringing the best people together to solve problems. My mantra is that we should always aim to onboard that person who is smarter than we are. I am committed to investing in the personal development of our people and encouraging everyone to reach their full potential."
