How it started

Founding

The sons of German immigrant and Minnesota farmer, George Klein, purchased controlling shares in The First National Bank of Chaska in 1907. Until that time, the two men, C.H. Klein and C.P. Klein, had been operating their father's brickyard. Klein had acquired the brickyard following a severe depression in 1893. It was the only remaining brickyard in Chaska which at one point had 11 individual brickyards in operation between 1857 and 1895.

C.H. Klein was elected to the Chaska School Board in 1900, to the Minnesota House of Representatives in 1902, and to the Minnesota Senate in 1910.

Expansion

The bank expanded west along the railroad as the Kleins helped organize banks in Victoria, Waconia, Montevideo, and Madison. Banks were also acquired in nearby Cologne and Young America during C.H. Klein's time as Bank President.
