Cornerstone Companies LLC was founded by Bob Singleton of Charlotte, North Carolina. Bob has been designing, fabricating and installing signs since 1984. Bob and his wife, Ruth, owned and operated a commercial sign company, Carolina Sign Company, Inc.  Carolina Sign Company, Inc. provided signs throughout the United States while their primary focus was on the Carolinas. Carolina Sign Company, Inc. made signs for a great many industries; Real Estate, Banking, Racing, Construction and even for Hollywood Movie Producers.   This vast and varied exposure helped Bob and Ruth decide what signs were of greatest interest to them. Today, they serve the clients they felt best qualified to serve:  churches, schools, military bases, municipalities, fire departments and businesses in need of marquee signs.

After serving on the Board of Directors for the United States Sign Council, Bob became convinced that many churches and schools throughout the US were paying far more than needed for standard institutional signs. In some areas, sign costs two or three times what they could. This formed a conviction for Bob to change the company's focus. The company's business model was changed to reflect the commitment to help people throughout the country save on their signs, focusing on serving clients nationally rather than locally or regionally.

In 1997 Churchsigns LLC was formed to serve churches and schools exclusively. In 2002, the name was changed to Cornerstone Companies LLC. Today, Cornerstone Companies has provided signs to churches, schools, military bases and businesses in 40 states.

Cornerstone works hard to help prospective new customers understand the differences in signs and why seemingly similar models differ in price. We never ask a prospective new customer to invest their valuable time talking with commissioned sales people that might ask someone to buy a sign they want them to buy rather than what best suites their needs and their budget.

Mission Statement
To treat our customers as we would want to be treated and to make the process of buying a new sign simple.

Purpose Statement
We will never settle for being just another average sign provider. We will as a team, each striving vigorously and creatively to be the very best provider of signs in the United States and abroad.
