公司简介

In 1944, Joseph Roland Cumberland opened Cumberland Optical Company in Silver Spring, MD, after training in his craft at the Washington Navy Yard. In the years following, the company expanded, became J.R. Cumberland Incorporated, and moved to its current location in Marlow Heights, MD. In 1959, J.R. Cumberland Inc. began a collaboration with Questar Telescopes that continues today. Roland's sons Stephen and Dwight Cumberland became owners of the company upon his retirement in 1997. In 2015, 30-year employees Robert Kautz and William Greening took over as owners, and continue the legacy of Roland's and his sons' dedication to providing reliable service and products to their clients.
