Why Hire Dunbar?

I just wanted to drop a line of appreciation and gratitude to Marty. Between Marty and Brian from Galloup, they took what I thought was going to be a nightmare of a repair (Saturday night before Easter when no one is open) and made it seem like a routine visit. Marty's "customer first" work ethic will keep me calling you guys in the future when I need some help around here.
