William M. Casey
William M. Casey is the EY Americas vice chair of transaction advisory services. He joined the firm in 1983. Over the last decade, he has worked to help double the talent and revenues of Americas TAS practices. Earlier in his career, he leveraged his fluency in both Spanish and Portuguese while working on company transactions in Latin America for over ten years.
Bill is a first-generation Irish American with both sides of his lineage based in Mayo. “The Irish culture is associated with humility, kindness, and a deep appreciation for these qualities in others,” he says. “I work hard to connect with those around me because I want to understand their strengths and how best to communicate with them. This enables all of us to work together and coalesce around our shared purpose of building a better working world.”
Bill was born in Chicago and attended the University of Illinois, where he obtained a degree in accounting. He earned his M.B.A. at DePaul University. He and his wife, Amy, live in Miami with their two children, Sarah and Hannah.
