Security State Bank (SSB) announced Friday that it will merge with Jamestown-based Unison Bank.

“We are excited that SSB will be merging with us, especially due to the history between our banks,” said Kelly Rachel, Unison Bank president and CEO. “Our staff has been working for months to ensure a seamless transition for all of SSB’s customers.”

Since its beginning, SSB has been in the business of serving its communities and customers. The bank's values along with SSB President and CEO Lorren Henke being involved with Unison Bank as an owner and chairman of its board of directors for the past 18 years made the transition natural when Henke announced his retirement.

“It’s been our life’s work and our privilege to help our customers achieve their financial goals and succeed,” Henke said. “For the past few years, announcing my retirement has been on the horizon. It was a priority to align with another bank that held our same values – values that put customers and community first. We found that perfect-pairing in Unison Bank.”

SSB customers will continue to receive exceptional service in addition to the expanded platform of quality products and technology options that Unison Bank will be able to offer.


Unison Bank originally began in 1965 in Jamestown. Since inception, its mission has been to provide its customers with quality products and services while recognizing each customer as an individual and respecting the customer's unique needs. In addition to its Jamestown, location, it also has a branch located in Gilbert, Arizona.

Unison Bank employs 63 team members between its two locations and will welcome Security State Bank’s nine employees to its team later this spring.

“We are excited to have this outcome for our employees, customers and our communities," said Greg Bosch, SSB branch manager.

The merger is expected to be finalized by May 24, 2021. Once merged, Unison Bank will have branch locations in Linton, N.D., and Wishek, N.D.
