Vanguard's chief information officer, John Marcante, is retiring after 28 years, the company reported.
He leaves in November and Nitin Tandon, Vanguard's current head of Retail and Corporate Systems within the Information Technology division, will take his place, overseeing all aspects of the company's use of technology globally.
Mercante, who joined Vanguard in 1993, has become "a pivotal leader of Vanguard's High Net Worth and Advice client groups," according to the company's announcement of his pending retirement.
"John led the company's complex cloud migration and transformed our Information Technology division with a keen focus on agile methodology and next-generation development," said Vanguard Chairman and Chief Executive Officer Tim Buckley, in a statement.
