SISCO began as a side project for Marion and Vrina Grimes in 1945. Marion, who worked as a salesman for a farm chemical company, became interested in the farm implement business as he visited his customers over a 19 county area in Ohio. He discussed his ideas with his wife, Vrina, and Superior Implement and Supply Company , or SISCO, was born from their kitchen table in Greenville, Ohio.

SISCO first sold stillcraft corn pickers, Allied Hoe (manufactured in nearby Ansonia), American Aggregate equipment, as well as other implements from several companies in Michigan.

In 1946 the Grimes’ decided to make SISCO their full-time work, and with the work quickly outgrowing their kitchen table, they incorporated in 1947 and moved their offices to the Weaver Building on Broadway in Greenville. By 1952, the company began expanding the product lines offered when it moved to its current location on State Route 571 west of Greenville.

In 1991, Jerry McConaha, the son-in-law of Grimes, took over as Owner and President. In 2005, McConaha sold the company to long-time employee Ben Overholser and his wife Gail. The Overholsers are the current owners and strive to keep Marion and Vrina’s vision of providing quality products and excellent service alive and well to this day. SISCO currently offers over 15 different quality product lines to its dealers.
