Southwest Bancorp is merging its banks in Kansas, Oklahoma and Texas into one national charter under the new name Bank SNB.

All banks owned by the $2 billion-asset Southwest, including Bank of Kansas in Reno, Kan.; Stillwater National Bank and Trust Co. in Payne, Okla.; and SNB Banks in Texas will operate under the name Bank SNB starting Nov. 16, the company said in a press release Thursday.

"For nearly 120 years, our bank has had the personality of a community bank [and]large bank resources, and we will continue to operate as such," Chief Executive Officer Mark Funke said in the release. "This charter consolidation and new name allows us to be unified as one bank and one brand across our entire footprint."

Southwest will introduce a new logo for Bank SNB to accompany the name change—a modernized update of Stillwater's trademark "S."

Southwest, founded in 1981 and based in Stillwater, Okla., has made other major changes in the past year. It completed its exit from the Troubled Asset Relief Program in May. Funke came on board as CEO a year ago after a nationwide search to replace retiring head Rick Green. The company also hired a new chief financial officer and named a new board chairman in November 2012.
