Don Callahan
TIME
I am excited to be part of the Modern Advisory Board. The talent agenda has never been more important than now. Mark and his team know how to identify unique talent and have proven track records in helping clients build winning strategies. They also know the importance of diversity and understand that the more diverse the team, the better the results. This is an industry in transformation and I look forward to assisting Modern in shaping the outcome.
Acknowledged internationally as a leader in both the financial services and technology industries, Mr. Callahan previously served as Chief Administrative Officer and Global Head of Operations and Technology at Citigroup. He retired from Citigroup in December 2018 and now serves as Executive Chairman of TIME. He also serves on the boards of Tata Consultancy Services, Ltd., WEX, Kore AI, Capco, and Accedian, a Bridge Growth Partners-backed company.
At Citigroup, Mr. Callahan managed a complex set of businesses and services spanning more than 100 countries, a multi-billion dollar operating budget and critical systems infrastructure including the bank’s cyber security initiatives. He most recently led a top-to-bottom transformation of operations and technology, helping move the global bank from a collection of independent and dispersed entities into a lean, fully integrated enterprise. Mr. Callahan also established globally consistent technology standards and governance, and migrated critical functions to an integrated, managed, shared services model. As a result, in 2017, Citi was named by the Gartner Group as the most efficient of all major global banks in generating income per dollar of IT spending. Earlier in his career, Mr. Callahan spent 12 years at IBM, where he held a number of management positions, including director of strategy for IBM Japan.
Along with Modern’s Board, Don is also on the business committee of the Metropolitan Museum of Art, a fellow at the Foreign Policy Association and on the boards of Columbia Teachers College and the American Red Cross New York Region. He holds a Bachelor’s in History from Manhattanville College, where he serves as trustee chair emeritus.
