In his role, Puthiyamadam is responsible for effectively executing the firm’s strategy within its Advisory service line and has direct oversight and responsibility for the service line's innovation, growth agenda, operations, financial performance, and quality.

“Grant Thornton is a team of dynamic individuals with a well-established and successful Advisory Services practice,” said Puthiyamadam. “I look forward to building on that foundation by working to set a bold new ambition for the team. We’ll adopt a tech-centric mindset, pursue innovation and growth, and deliver high-quality outcomes for clients across a range of industries and transatlantic markets, while also benefitting our firm and our people.”
