More About Norpro

In January 1986 Tom and Anne Mondelci established Northeast Isuzu Engines/Norpro. Mr. Mondelci had introduced Isuzu diesel engines five years earlier and was now setting up a company whose sole purpose was to distribute Isuzu diesel products to the Northeastern United States.

Norpro quickly became recognized as one of the leading distributors of Isuzu diesel products in the United States. Norpro’s growth and recognition were due to Norpro’s core belief in exceptional customer service and satisfaction, and in the selling of outstanding products- Isuzu diesel engines. Norpro grew very rapidly and in 1988 Mr. Mondelci began designing and manufacturing generators under the Norpro trademark. Norpro’s philosophy was simple:

  • Build a product that was dependable and reliable in all kinds of operating conditions
  • Use the best technology available
  • Make a product that was simple to operate and easy to maintain
  • Provide the best pricing in the industry

Norpro had become more than just an engine/parts distributor. It was now a manufacturer and its reputation for building a quality product that was highly reliable and affordably priced fueled its growth to a company that now distributes power generation products all over the world.

One thing has not changed and that is that Mr. Mondelci is still guiding Norpro in its everyday business but now his two sons Thomas and Jared assist him. Norpro has the feel of a small business whose core values of customer service and satisfaction remain firmly in place.

Norpro now manufactures products which address multi-industry power generation needs such as commercial marine, recreational boating, agriculture, forestry, recreational vehicles, homeowners, portable power, standby power, and many more. Norpro continues to build its reputation based upon exceptional customer service and satisfaction and products that are the best in the industry.

Norpro has had many notable achievements since its inception in 1986. Norpro continues to develop and distribute new products, which allow it to appeal to an ever growing customer base. Norpro manufactures a full line of alternative fuel based generators using Nissan and General Motors power plants. Norpro builds portable power generators, industrial and marine pumps along with natural gas standby power units.

In 2002 Norpro has developed sound attenuation devices (sound shields) for its line of marine generators, which allows the quietest generator operation in the marine industry. At the 2003 Miami Boat Show Norpro introduced its newest line of generators powered by the popular Yanmar series of diesel engines. These units are ultra light, ultra quiet, compact and feature the latest technological innovations and features.

Research and design efforts are ongoing, the purpose of which is to allow Norpro to maintain its lead in technology, price and customer satisfaction.
