Kerkhoff Brothers was originally formed in 1973 as partnership between 3  brothers farming 750 acres. The company eventually grew to one of the  larger independent seed corn production operations in the world. 

 Today, the company is a partnership between Phil Kerkhoff, his wife, and  three children.  Although Kerkhoff Brothers maintains roots in  Agriculture, it has evolved into a family investment office with a  variety of business interests.
