Frost Bank added James Waters and Mike Russell to its executive team.

Waters, recently a partner with the Haynes and Boone law firm in Dallas, will join in February with the title of group executive vice president and general counsel. He also will serve as secretary to the Cullen/Frost Bankers board of director.

“We are extremely pleased to have James Waters join our executive team. He has demonstrated a high level of success as a world-class corporate lawyer and we’re glad to have him join the Frost family,” said Frost Chairman and CEO Phil Green.

Waters will succeed Stan McCormick as Frost’s senior legal officer and secretary to the board.

Russell, a former corporate technology executive, a longtime management consultant and author of the book “Wrong Until Right,” will join Frost immediately as group executive vice president and chief operations officer. He will succeed longtime group executive vice president Gary McKnight, who will retire in June.

“Mike Russell is familiar with Frost and its culture through his work with us over the years, and he will be a great addition to our leadership team,” Green said. “I want to thank Gary McKnight, who has been with Frost for more than 45 years and who has provided leadership and excellence in all the positions he has held in operations and technology. His expertise and guidance have been instrumental in Frost’s growth over the years.”

San Antonio, TX-based Frost is the banking, investments and insurance subsidiary of Cullen/Frost Bankers, a financial holding company with $31.7 billion in assets as of Dec. 31, 2017.
