Staff Writer | March 10, 2016

ACORD, the insurance industry’s global data standards and services organization, announces that William N. Pieroni was elected by the board of directors as its new president and CEO. Pieroni succeeds Gregory A. Maciag, who announced his plan last year to retire after nearly 40 years with the organization.  Maciag was also named president emeritus of ACORD and will be an advisor to the organization.

Pieroni served as the global chief operating officer of Marsh. Additionally, he was the chief technology and transformation officer across the risk and insurance segment. He has significant experience in the insurance industry and a track record in helping to facilitate improvements in a sustainable manner across a variety of organizations. 

Prior to joining Marsh, Pieroni was senior vice president and part of the office of the chairman at State Farm. Prior to that, he served as Aon’s senior vice president and global CIO with responsibility for operations across retail, wholesale, and reinsurance brokerage. His insurance and financial services background also includes general manager of IBM’s insurance business, a partner at Accenture and consultant with McKinsey & Company.  

Pieroni earned his Bachelor of Science in accounting from the University of Illinois.  He also received his M.B.A and was named a Baker Scholar from Harvard University School of Business Administration.

“Bill Pieroni is an example of the best in our industry. He is a strong leader with deep knowledge of the insurance business and a vision for the future success of ACORD,” says Sal Branca, senior vice president of AIG and chairman of the ACORD Board of Directors. “Bill’s enthusiasm, passion for innovation and understanding of the limitless opportunities ahead will bring valuable perspective.  ACORD has a long and proud history of thought leadership and I look forward to working with Bill and could not be more excited for ACORD’s future.”

John Leonard, president of MEMIC, chairman of the ACORD search committee and immediate past chairman of the ACORD board of directors adds, “I am so pleased to bring one of the industry’s top leaders to ACORD. Bill has an outstanding reputation. He served on the ACORD board of directors for the past 10 years, so we know him well and he knows ACORD.” 

Maciag says, “With four decades at ACORD, I am truly proud of our success. The future continues to be filled with opportunities and I can’t think of a better leader than Bill Pieroni to continue the ACORD journey.”
