OUR NAME
Manhattan Legacy Service is based on the history of the Manhattan project, its association with Oak Ridge, and the legacy of the area and our team. One of the definitions of “legacy” is “software that is difficult to replace because of its wide usage.” Another definition is “something conveyed from one person to another.” This is how we want MLS to be recognized- conveying our knowledge to your project and employees.
