Zeller's Ace Hardware is a mom-and-pop operation with two locations in town. The friendly shop offers service with a familiar face. "Hey you" and "hey buddy" are standard greetings. This is where plumbing or maintenance businesses and homeowners alike come to get their hardware supplies. Zeller's is linked to the original hardware store of Napa that goes all the way back to 1855. Owners Dick and Irene Clark took over in 1995.
