NASCO’s corporate headquarters is located in Kellogg, Idaho. We have a network of offices in 2 countries and 30+ states, literally from coast to coast. 

NASCO began as a small disadvantaged business in 1998 and graduated from the SBA 8(a) program in 2008. Since that time we have continuously grown in size and capability. We are now classified as a large business. As such, we recognize the value and understand the requirements of using small business service providers to perform federal contracts. NASCO has gained considerable value for our customers by involving members of the small business community in the performance of our federal contracts.

NASCO is always looking to team with integrity-driven, skilled professionals and organizations in construction-related fields. Whether we are teaming with a nationwide organization or specialty local firm, we offer our private and federal clients a full range of construction options.
