Building a better working world

"My current focus is providing auditing services, which play an important role in the economic system: they help ensure companies maintain the trust of society.

Each day, I work to improve as a professional and ensure that there is mutual respect and cooperation between our client companies and EY, in our role as auditors.

I also make a point to share this perspective with my colleagues and fellow team members.

I want to be a facilitator for this exchange, and it often helps to bring a smile in whatever I do, whether at home or at work."
