Southwest Bancorp Chairman Bob Rodgers said the board was pleased that Funke agreed to take the job.
“Mark brings a deeply rooted knowledge of the industry and a pioneering vision for the company that uniquely fits our heritage and core beliefs,” Rodgers said in a statement.
Stillwater National Bank, based in Stillwater, has assets of $2.3 billion with offices in Oklahoma and Texas. Its sister company, Bank of Kansas, is based in South Hutchinson, Kan.
Stillwater National Bank is the seventh-largest bank in Oklahoma, based on deposits. Bank of Oklahoma is the largest deposit-holder in the state, according to the most recent FDIC figures.
Funke said the bank he's joining, while much smaller than Bank of Oklahoma, is larger than Bank of Oklahoma was when George Kaiser bought the company in 1991.
“I've been able to watch and participate in BOK's growth over the years and I can use some of those skills here and help that organization also grow and prosper,” he said.
Funke said it was hard to leave Bank of Oklahoma after so many years.
“The relationships I have with the people here and the quality of the bank, those kinds of things make it very difficult after this long a period of time,” Funke said.
Funke said he will remain in Oklahoma City and occupy an office in Stillwater National Bank's administrative building in the Waterford Office Complex.
