In 1978, Joel Bleth & Willard Tormaschy, two industrial engineers fresh out of the University of North Dakota at Grand Forks, founded a company called Pump Systems Incorporated (PSI) in Dickinson, North Dakota. From 1978 to 2006, PSI built an excellent reputation both nationally and internationally as a supplier of custom-designed pumping systems for a variety of industrial uses from mining, refining, oilfield, & agriculture to contractors, municipalities, & manufacturing. An independent third-party performance review in 2004 on behalf of a U.S. Government Agency scored PSI an exceptional 91%.

The original SolarBee® technology was developed by PSI in the late 1990s and it became apparent just how much the water quality industry needed reliable and cost effective real-world solutions. The SolarBee® Division was created soon thereafter and in 2006, the Company re-organized to focus exclusively on reservoir treatment technologies and water quality improvement.

Medora Environmental Incorporated is the parent company for two wholly-owned subsidiaries, Medora Corporation (Medora) and Medora Transport Corporation. In the proud tradition of PSI, Medora continues to provide great service to its Customers across the United States, Canada, and is a world leader (26 countries and counting) in sustainable reservoir water quality improvement.

The Medora Main Office & 45,000 sq. ft. Manufacturing Facility are located on 19 acres just north of Dickinson, North Dakota. Dickinson and its surrounding communities are home to the majority of Medora Employees including scientists, engineers, manufacturing personnel, and factory-trained service technicians. Medora also has ten (10) U.S. Regional Offices from coast to coast and an International Sales Office in Fargo, North Dakota.

Joel and Willard continue to own & operate Medora and are still at work every day.

Why “Medora'?

The town of Medora, North Dakota is located just 40 miles west of *Dickinson and is in the heart of the scenic North Dakota Badlands. Medora symbolizes the integrity, hard work, and entrepreneurial spirit of one of its most famous citizens, **Theodore Roosevelt (or “TR' as he is locally called). After his time in North Dakota, TR went on to become the 26th president of the United States from 1901-1909. He was a remarkable person who clearly understood the difference between action and talk. He is often quoted in this regard and it is in this spirit we took the name Medora.

*Dickinson, North Dakota is the home of the Theodore Roosevelt Presidential Library.
