NSVI’s Fond du Lac location, once a rented facility accommodating 8 employees, is now a 12 acre campus under full ownership of NSVI. On the grounds are housed sales, production and storage areas. A second NSVI production facility operates out of Bulgaria. Its products are exported to the United States, further expanding the available product line. With over 130 years of combined experience in the fields of quarrying, marketing, geology and accounting, NSVI has turned talent and dedication into a moving force in the stone industry.
