Jubal and Jennifer Margroff purchased Dennis Lumber Co, Inc in 2015 with a vision. Since then they have not only added on to the hardware store but completely renovated it, rebranded, added new concrete mixer trucks, are adding a new rental division and are currently adding a new lumber building. Something tells me these go-getters aren't going to be stopping there!
