Mountain Companies was formed by two East Texas families in 2009. Under this umbrella, they established Mountain Supply and Service, LLC (MSS) to be an oilfield supply and service company initially focused on the relatively new activity in the Marcellus Shale.  The first MSS location opened in Triadelphia, West Virginia in June of 2009.  The quality of the service and products MSS provided took hold quickly and a second location was established in Williamsport, Pennsylvania in October of 2009.  In June of 2010, at the request of one of MSS's largest customers, MSS opened its third location in Richardton, North Dakota serving the Bakken Shale.

MSS has grown to be a one-stop-shop for oilfield needs in the completion of horizontal wells - providing Completion Chemicals, flow iron, pump parts, O-rings and gaskets, gauges, flowback parts, general supplies and more.  MSS's unmatched service and expanded product offering has allowed us to add locations in Windsor, CO; Midland, TX; and St. Clairesville, OH.

As Mountain Companies continues to expand its product and service offerings within the Oil and Gas Industry, our mission will remain focused on building strategic parternships with customers by providing value through exceptional service and product-based solutions.
