Northern Stone Supply, Inc. is a leader in quarrying, fabricating, and marketing a wide range of Quartzite and Granite products from our two world class quarries located near Oakley, Idaho and Park Valley, Utah. Our roots and experience with natural stone quarrying and distribution come from over 60 years of doing business internationally. In spite of our widespread reach, NSS is headquartered in a small agricultural community in Southern Idaho where integrity matters as much as the people we work with. We trust you will find that for Northern Stone Supply, Quality First is much more than a slogan.

In 1952, Gary Mullard hauled the first loads quartzite down from Middle Mountain in the back of his pickup truck and started a business that none of the locals thought would get very far. His passion for

excellence and quality shaped our company from the beginning, and his efforts lead the introduction of Oakley Stone Quartzite to the natural building stone market. In 1970, Northern Stone Supply was officially incorporated and we began to develop a large range of products in order to meet architectural requirements for both residential and commercial projects throughout the world. In 2005, Greg Osterhout joined the team to guide the growing business. Innovations in quarrying, manufacturing and distribution have allowed us to become an international company, with hundreds of distributors both large and small. Since the 50’s, Northern Stone Supply’s operations have expanded vastly, but we pride ourselves in the fact that our home-grown reputation for outstanding customer service and quality products is still our number one concern.
