How Greg is building a better working world

“As I am working with clients across the energy sector, I want to help them realize that transformation starts with having the right people and processes in place, and where EY teams can help. Having led people in several very large organizations, I know first-hand the importance of thinking long term about how the organization is structured and building processes that will weather the transition.”
