Our Birth

Our Birth-  Berens Construction, Inc. was founded by Bob Berens in 1976.  Bob grew up in Dunlap, IA, and moved to Omaha, NE after he graduated high school.

In an effort to make extra cash, (due to a low paying job), he borrowed tools from a neighbor and worked to complete small construction jobs on the side.  He soon realized he had an eye for exterior home remodeling, and started landing subcontract work frequently.  His successes as a subcontractor eventually led to the idea of starting his own business.
