How Simon is building a better working world

“I ensure our advice helps clients solve problems, assess investments and make decisions which provide the best outcomes for their business. Leading a team to provide stand-alone services, or integrated with other EY teams, I work with talented people to bring a full service offering to clients across the transaction life cycle.
