Incorporated in 1984 under the name Pennyrile Computer Services, the company began business with four employees primarily working in the Hopkinsville, Kentucky area.

In 1991, the company name changed to Cornerstone Information Systems, Inc.  which better describes the broad range of services and products we provide.  Our company name also expresses a commitment to Christian business principles and our desire for Jesus Christ to be the "Chief Cornerstone" of our business.
