TS Bank Locations and History


In 1902, TS Bank was opened in Treynor, Iowa which became a chartered bank in 1923. Since then, TS Bank has continued to expand with additional locations in southwest and central Iowa. View all of the current TS Bank locations here.

TS Bank's first step into growth was in the year 2000, opening a new location in Macedonia, Iowa. Macedonia is a town 11 miles southeast of Treynor. The small town had a bank that changed hands multiple times before TS Bank came into town. TS Bank hired the former bank's employee, Vicki Putnam, to work at the new branch until she retired in 2020. The building was remodeled, bringing back some of the original look and feel, including removing a lowered ceiling and restoring arched windows. 

HyVee - Council Bluffs

In November of 2005, TS Bank opened a branch inside of the Hy-Vee grocery store located at 1745 Madison Avenue, where interstate 80 meets Madison Avenue in Council Bluffs. This was TS Bank's first location in Council Bluffs and the Omaha MSA. 

West Broadway - Council Bluffs

In March of 2013, TS Bank opened its first free-standing location in Council Bluffs located at 3201 W Broadway. This location features two drive-thru lanes and includes an exterior ATM. 


In December of 2015, TS Bank opened a new location in Atlantic, Iowa. TS Bank purchased a building that formerly housed an insurance agency located at 1005 E 7th Street and remodeled the space before opening. This location features an exterior Video ATM that converts to a 24 hr. ATM after-hours, considered new technology in the banking world, in the drive-thru. 


In August of 2016, TS Bank acquired Okey-Vernon First National Bank in Corning, Iowa from Blue Grass Bancorporation, Inc., with banking assets of $85 million. With this acquisition came a wonderful group of long-time employees, many who still remain at the bank today. This location features a walk-up and drive-thru along with a Video ATM and regular 24 hr. ATM.

Downtown - Council Bluffs

In October of 2016, TS Bank opened its downtown location at 43 Scott Street in Council Bluffs, Iowa. The four-story building houses not only the first-floor bank branch, but the company's trust department, TS Prosperity Group, on the fourth floor. This location features a Video ATM that converts to a 24 hr. ATM after hours in the drive-thru. 


TS Bank is working on its eighth location in Ames, Iowa at 402 Lincoln Way. Currently, the location serves as a loan production office but has aspirations of growing into a full-service branch location someday in the future. Read more about the new Ames office here

To achieve this goal the TS Banking Group must: one, preserve the "local touch" at each community bank by allowing the acquired bank to focus their efforts on serving their clients and communities where they are located, and two, harness the power of a multi-bank operating group to provide a high level of technology, risk management and financial management.
