Our Quad Cities Roots Run Deep.

We started with Northwest Bank & Trust Company in 1941.

Northwest Investment Corp. was formed in 1997 when the Slavens family consolidated all its business enterprises under the ownership of one family holding company. Today, members of the Slavens family continue to own 100% of Northwest Investment Corp., we are delighted to be headquartered in the Quad Cities, and we are proud of our “family” of wholly-owned companies doing business across the country.
