About Us

In 1929, George B. Gray saw the need for the expertise and dependable service in the septic service industry so he formed the company George B. Gray. In 1944, his brother, Robert, became a partner after his tour of duty in World War II.  They renamed the company Gray Brothers.   The company is now a third-generation family-controlled and operated firm. Gary Gray and Brian Gray are the principals of the company today.
