Company History

Cornerstone Controls Inc. has served the needs of industrial process customers for more than 80 years.

• In 1991, Cincinnati, Ohio based Reams Controls, and Indianapolis, Indiana based Acme Controls, merged operations and formed Cornerstone Controls Inc. Both organizations had been representatives of Fisher Controls since the 1920's.
• In 1992, Emerson acquired Fisher Controls. Emerson subsequently signed Cornerstone Controls to be its local business partner serving customers in Indiana and Southern Ohio.
• In 1997, Cornerstone acquired Prologix, an independent process automation and engineering services company serving customers from a base in Indianapolis.
• In 1998, Cornerstone acquired Donovan Controls, an Emerson local business partner serving Kentucky customers from its office in Louisville.
• In 2005, Cornerstone acquired Michigan I&C, an Emerson local business partner serving Michigan customers from its office in Plymouth, Michigan.

Though we have grown over the years, we still serve our customers as a local company from four office locations in Cincinnati, Indianapolis, Louisville, and Plymouth.
