Michael P. Pinto, who rose to high-ranking roles at M&T Bank Corp. in his long career there, has died after an extended illness. He was 58.

The bank said Pinto died Tuesday. In January, M&T announced Pinto was scaling back his duties to concentrate on his treatment. Details of his condition were not disclosed.

“M&T has lost a great friend and a great leader, but Mike’s contributions to our company have not ended,” said Robert G. Wilmers, M&T’s chairman and chief executive officer, in a statement. “Indeed, his impact and influence will continue long into the future.”

Wilmers said Pinto “helped build M&T – not just in size, but in strength and stability as well. Throughout his tenure, Mike has been both a conscience and a compass, helping to instill the values that define who we are and what we do, while playing a leading role in charting the course of the bank’s strategic direction.”

Pinto, a native of India, joined the bank in 1985, just out of the University of Pennsylvania Wharton School of Business. In 2007, he was named vice chairman of M&T’s board. Earlier this year, he resigned from the board of directors but continued to serve as vice chairman of M&T Bank, the primary banking subsidiary, “on a part-time basis in an advisory role.”

Pinto held a number of significant roles at M&T as he ascended its leadership ranks. He was named executive vice president and chief financial officer in 1996. In 2003, he was appointed vice chairman of M&T Bank and was elected to the boards of M&T and its banking subsidiary. Another key appointment came in 2005, when he was named chairman and chief executive officer of the mid-Atlantic division of M&T’s banking subsidiary.

He is survived by his wife of 34 years, Priya, and their two children.
