Our Story

Driven by values and innovation since 1993

With over 40 years of combine manufacturing experience, Concept Assembly Solutions’ dedication to continuing the entrepreneurial spirit and striving for excellence has never been stronger.


The legacy began with Joseph Geisel in 1978, with a commitment to customer relationships, quality products and innovation that was passed down to his family; Mike, Larry, Kevin and Kathy Geisel – and now grandchild, (CAS President), Katie Geisel Widmeyer. 


Both domestically and internationally, Concept Assembly Solutions is here to work with your team to provide the most cost effective, efficient, and creative solutions to your assembly, value-add or secondary operations need.
