The company was searching for a solution to help improve profits. Dave Haimbaugh’s father started the business back in 1946. Three of his other sons and Dave, who is now 60, have played a role in its operations ever since.

The family legacy promises to continue as Haimbaugh says he has two of his nephews now working in the business.
