Lest we forget!

Normandy Marks D-Day's 79th Anniversary, Honors WWII Veterans!

On the morning of June 6, 1944, Allied forces staged an enormous assault on German positions on the beaches of Normandy, France. The invasion is often known by the famous nickname “D-Day,” yet few people know the origin of the term or what, if anything, the “D” stood for. Most argue it was merely a redundancy that also meant “day,” but others have proposed everything from “departure” to “decision” to “doomsday.”


Excel Communications LLC will be closed on Monday 29 May 2023 in observance of the Memorial Day holiday - please remember our military's fallen heroes - they ARE our heroes!!
