In 1974, Bob was selling real estate for the company that bought the right to sell Century 21 franchises in Michigan. His brother-in-law was a carpenter, and Bob knew the real estate business. They were both looking for a change. So, they began supplying and installing the colonial post real estate signs that Century 21 required. Within a few years, other real estate companies hired them.

Around 1990, Bob was approached by Pulte Homes. Since Bob had the drilling equipment that could penetrate the frost, they wondered if he could install some mailboxes for them in a new subdivision in Canton, Michigan. Of course, Bob said, "YES!!" And the relationship continues to this day.

Through the years, many other builders have called on Mailboxes By Bob / Commercial Sign Co. to supply their mailboxes as well as thousands of their subdivision signs. By the time Bob sold the real estate sign company to its new owner in 2004, they were supplying and installing over 30,000 real estate signs per year.

In 2014 Bob sold Mailboxes by Bob / Commercial Sign Co. to its new owners Jay and Kelly. And so began Big Bore Signs, LLC. Jay started working for Bob in 2003. Over the years Bob has mentored Jay and taught him the ins and outs of the Mailbox and Sign business. Jay and Kelly plan to continue providing excellent products and services along with total customer satisfaction. Jay and Kelly hope to make Bob proud by working hard to maintain his pristine reputation. They know what big shoes they have to fill.

Mailboxes By Bob / Big Bore Signs, LLC continues to concentrate on builders, developers and homeowner's associations, supplying them with street signs, main I.D. signs and mailboxes.
