For over a century, Frank Miller Quartersawn Hardwood has been a family-run business continuously operating at its 20-acre founding location in rural Union City, Indiana. From filling small orders for local farmers with crosscut saws and steel-wheeled wagons, we have grown into a thriving, global enterprise employing state-of-the-art sawmill and kiln drying technology. Frank Miller specializes in manufacturing quartersawn hardwood lumber with the bulk of its production in white and red oak. Other quartersawn hardwood species include cherry, hickory, hard maple, walnut and poplar. Although we don’t manufacture plainsawn hardwoods, we purchase high-end, quality green lumber from reputable local sawmills. This lumber is dried in our kilns, graded and sold through our distributor network. Today, we are one of the world’s largest producers of quartersawn hardwoods. Approximately 200 employees work at our original Union City mill and at our kiln operation and concentration yard in Salem, Indiana.
