Frank Steffner founded "The Shop"

five generations ago in 1890. He started with repairing armatures in streetcars, a main form of transportation for Chattanoogans. The Steffner family has grown Chattanooga Armature through the decades from repairing to sales and service of more than just electric motors for Chattanooga businesses.
