Bill Casey

William (Bill) M. Casey is the EY Americas Vice Chair of Transaction Advisory Services (TAS), which helps organizations work better by raising, preserving, investing and optimizing capital. Having launched his TAS career more than 30 years ago, TAS’s history is Bill’s history.

In his capacity as a partner of Ernst & Young LLP, he advises clients on capital strategy, mergers and acquisitions, public company spinoffs, IPOs and securities offerings. Bill has led some of the firm's largest client engagements, including cross-border transactions for major multinational corporations and leading private equity firms, and has deep experience in the beverage, automotive, fintech, telecom and professional services sectors. Bill previously served as EY’s Americas TAS Deputy Managing Partner, Americas TAS Chief Operating Officer and TAS Leader for the Southeast Region. Over the last decade, he has worked to help double the talent and revenues of Americas TAS practices, which now number more than 4,000 professionals based in the United States, Canada, Mexico, Israel, and Central and South America.

In addition to presiding over the practice’s record annual revenue of more than $2 billion, Bill has helped transform TAS from transaction compliance and due diligence providers into market-leading strategic advisors. Integral to this transformation was the US firm’s acquisition of The Parthenon Group in 2014, which significantly enhanced TAS’s front-end strategic offering.

Prior to his current role, Bill spent more than a decade with EY firms working on transactions in Latin America. In 1995, he was the first on the ground to help launch TAS services in South America, which has since grown to over 700 people. Bill was made an Ernst & Young partner in its São Paulo office, where he helped develop TAS practices in both Brazil and Mexico and worked on the largest-ever beverage deal in Latin America. Bill serves as a member of the EY Americas Operating Executive and the EY US Executive Committee and is a Certified Public Accountant. He received his master’s degree in business administration from DePaul University and bachelor’s in accounting from the University of Illinois. He is fluent in English, Spanish and Portuguese and is a competitive triathlete.
