DNESCO is a full service Union Electrical Contractor that has been providing quality service in Southeastern Wisconsin since 1959. Our full fleet of service vehicles and 48-foot bucket truck help us handle a wide variety of electrical tasks, specializing in commercial and industrial projects.

COMPANY HISTORY: In 1959, Dave Nowicki founded DN Electric Service Company. The company provided quality electrical work throughout Southeastern Wisconsin for 17 years. In 1976, Lee Hollenbeck purchased the company and changed the name to Dnesco Electrical Contractors. Dnesco was purchased in November of 1997 by Joseph Klein and became Dnesco Electric, Inc.

Dnesco has since enjoyed steady growth and has continued to provide quality commercial and industrial electrical work in Southeastern Wisconsin. Dnesco experienced further growth with the acquisition of Elm-Brook Electric in 2002. This merger allowed Dnesco to strengthen its design/build department and bring together more resources to better serve its customers. Joe Klein, President of Dnesco, entered the electrical contracting business as a Material Handler in 1969. He later completed his Apprenticeship, became a Journeyman Electrician, a Foreman, and then a Superintendent. Before purchasing Dnesco, Joe was the Vice President of Operations at another local electrical contracting firm. In addition to Joe's daily duties at Dnesco, he is currently Chairman of the Milwaukee Area Joint Apprenticeship and Training Committee (JATC) and serves on the Board of Directors for the American Subcontractors Association (ASA).
