Industrial Equipment Sales & Service
Industrial Equipment Sales & Service has been supplying high quality products and services to the oil and gas industry in western North Dakota for over 10 years. 

In July of 1999, with the downturn in business, Stewart & Stevenson sold the Williston branch and territory; leaving the area with no industrial equipment provider.  With a combined 56 years of work experience in the natural gas, oilfield and industrial business, co-owners Stew Vachal, Rory Anderson, and Dean Klein took advantage of this opportunity to form Industrial Equipment Sales & Service. 

Vachal, Anderson and Klein were able to hire 8 of the 11 employees that were left after Stewart & Stevenson left, adding an additional 45 years of experience in the field.

IESS is continually adding new products and expanding the business to fit the growing needs of the oil and gas industry in and around Williston, ND.  Our goal is to join hands with you as a customer or vendor, to supply high quality products and services that will fit with our high quality staff.
