Santander Holdings USA has appointed Mahesh Aditya as chief risk officer.

Aditya, who joined Santander in March 2017 as chief operating officer, will take over risk management functions across the United States from Brian Gunn, who has assumed a new role as a special risk adviser to Santander Holdings USA Chief Executive Officer Scott Powell.

“These leadership appointments come at an important turning point for Santander in a year where we have made several significant strides on the regulatory front,” Powell said. “Our commitment to well-developed risk management and governance processes remains among our highest priorities as we continue to build on an already strong year for Santander U.S.”

Aditya will continue to serve as CRO for Santander Bank, N.A. and as a member of the boards of Santander Consumer and Banco Santander Puerto Rico. Prior to joining Santander, Aditya served as chief risk officer and a member of the operating committee for Visa.
