About PremierBank

PremierBank was originally organized in 1863 as The First National Bank and has served the Jefferson County area continuously since that date. In 1975, the Bank changed its charter to become a state bank and changed its name to First American Bank & Trust.

The North Drive Up location was built in 1986 in preparation for the Main Street location being expanded. The South Drive Up location was built in 1993 to serve our customers while the Main Street bridge was closed for construction.

First American Bank & Trust decided to expand outside Fort Atkinson in 1995 and began a branch in Johnson Creek, first operating out of a mobile banking unit. The building in Johnson Creek was finished the following year.

In 1998, First American Bank & Trust purchased the two branches of Jefferson County Bank and became PremierBank.

PremierBank expanded with a grocery store branch in 2000 when Pick 'n Save opened on the west side of Fort Atkinson. This branch offers extended evening and weekend hours.

In November 2003, PremierBank purchased the deposit accounts of the Johnson Creek and Sullivan Associated Bank branches, keeping the Sullivan branch open to make a total of eight PremierBank locations.

The decision was made to grow into Rock and Walworth Counties in 2017. That August, PremierBank purchased Commercial Bank with locations in Janesville and Whitewater to make a total of nine PremierBank locations.

The heritage of the combined Fort Atkinson, Johnson Creek, Jefferson, and Sullivan banks includes:

The first bank in the county;
The first bank to offer drive-through services;
The first bank to have its own trust department; and
The first bank to be on the Internet.
