Our History

In 1982, after working in design/build feed mill construction and as Regional Manager of Engineering for Continental Grain Company, Richard Kobetz, P.E., formed Sunfield Engineering, Inc. with the goal of providing engineering services tailored to the specific needs of clients engaged in the handling, processing and storage of grain, feed and dry bulk materials. From his construction engineering background, Richard knew there were many companies in need of impartial technical assistance in planning and executing capital projects, but could not afford their own engineer on staff. To make professional engineering accessible and affordable for every client, Sunfield would focus on the economics of sound engineering decisions: Engineering should not only pay for itself, but should contribute to the client’s bottom line. Since opening, Sunfield has continuously served both family-owned businesses and major national and international corporations.
