Where We Started
None of this happened overnight. Milton R. Underwood founded Underwood Distributing Co. in Grand Rapids, Michigan, in 1973. In the early days, he drove from one office supply store to the next, selling calculators and office supplies out of the back of a big groovy van.
Growing Up
Milton later passed the business on to his son, Miles, who kept it moving forward. Under Miles, the company sold calculators from Sharp, Texas Instruments, Casio and Canon, along with photocopiers, printers, ink, toner and paper. From the late 1990s through the early 2010s, Underwood gradually moved away from direct sales and became a modern wholesale distributor.
A New Chapter in Georgia
In 2018, Lost Mountain Commerce, LLC was founded in Georgia to refurbish and resell handheld and desktop educational electronics. In 2022, Lost Mountain Commerce merged with Underwood Distributing Co. and moved the headquarters from Grand Rapids to Austell, Georgia. The company kept the Underwood Distributing name to honor the legacy Milton and Miles built, and it has been growing ever since.
The Legacy Continues
More than fifty years after the first van route, our goal is the same: make good calculators and classroom technology easy to get and affordable for the educators and students who rely on them. If you need help choosing the right calculator, setting up a large order, or keeping a classroom set running, get in touch. We're happy to help.
