Granse/Trio Sales, LLC. originally formed in 1946 as Granse Corporation, has enjoyed over 75 proud years as a Manufacturer’s Representative serving the plumbing, water works, industrial, utility, municipal and irrigation industries through the wholesale chain. We are an aggressive Sales Agency and have spent many years reinvesting our profits to build the result of which we are profiling for you.

​

During this half-century we have humbly achieved the representation of some of the most well-known and respected national manufacturers within our industry. It has taken a lifetime of hard work, devotion, and four-generations of the Granse name to obtain this result.

​

After 43 years at the helm, Gordon E. Granse, the companies previous Chief Executive, was the third generation of Granse, having assumed control of the company from his father, Eugene in 1963 at the age of 20.  In April 2006 Gordy passed the control to daughter Kim and son-in-law Jeff Olson, remaining a wholly owned family sales agency and the fourth generation of Granse to own and run the company.

​

In 2017, in an effort to deeper penetrate the emergent markets and grow the company footprint, Charlie Loth joined the team as part owner. The agency is run based on the golden rule, going to market ethically and making decisions and acting upon them, in a manner that coincides with these beliefs. At Granse/Trio Sales, LLC. our customers come first.

​

Manufacturers represented by our agency will allow us to do business in a manner that melds with our morals and values. We are always striving to obtain a totally professional sales agency.

The Sales Agency's geographic market includes the entire states of Minnesota, North Dakota, South Dakota, Wisconsin, the upper peninsula of Michigan and most recently added, Northern Illinois, Iowa and Nebraska.
