We’re family owned and operated. We live and work in the center of Cornelius Country. This gives us a keen understanding of local growers’ needs. That’s a far cry from having corporate headquarters in a metropolis or foreign country.

"Why Cornelius seed?  Because of the Cornelius family and the sales representative, Lium family. They provide the knowledge in seed varieties that work for our farm. It doesn’t hurt that both are family run operations and owned by the families not share holders!!"
