How Bill is building a better working world

Bill has helped transform the EY SaT practices from M&A compliance and due diligence providers into market-leading strategic advisors. Integral to this transformation was the acquisition of The Parthenon Group in 2014, which significantly enhanced SaT’s front-end strategic offerings.

With more than a decade of M&A, IPO and capital strategy work in the region, he was instrumental in growing EY in Latin America.
