In 1954, Tom Dolan and Ralph Feldhaus were selling equipment to power companies.  They started their own company at the beginning of 1955.  Over the next 32 years, they introduced new suppliers and new technologies to the utility community in the upper midwest.  In 1987, I took over the company.  The company continues to introduce new suppliers and ideas to the same marketplace.  I am a Michigan State University Engineering graduate supported by experts of the companies represented.
