Power Systems was founded in 1966 by Harley E. Bergren. In 1982, Mr. Bergren retired and placed the operations of the business in the capable hands of Gary Bergren, his son, and David Thun, his first employee. Under the leadership of these two individuals, the Company has dramatically increased its product offerings and expanded its geographic reach.

Today, Power Systems is a leading distributor of hydraulic fluid power equipment, such as pumps, valves, gear boxes, differentials, hydrostatic transmissions and motors. The Company’s products are sold predominately to OEMs located in the Upper Midwest.

Power Systems has three other locations (Sioux Falls, SD, Ankeny, IA, and Richfield, WI) in addition to its headquarters site, and currently employs 49 people.

He earned a two-year degree in Fluid Power from Granite Falls, Minnesota College and has been instrumental in developing most of the operational departments in the Company, inside and outside sales,and the engineering department.
