Glenn and Eldon Johansen's experience first started from wiring hospitals, schools, and high rises in the state of Nebraska and other neighboring states under Claussen Electric. Claussen Electric was started by Eldon Johansen and others in the early 1960's. Johansen Electric was then established by Eldon and Glenn Johansen in 1976. Glenn was an apprentice under his father and later obtained his electrical contractor license in 1984, which is the highest license attainable by an electrician. After obtaining his license, he obtained his Associate Degree in Science for heating, ventilation, and air conditioning through Northeast Community College in 1980. Johansen Electric was later taken over by Glenn Johansen in 1989, in which he is now serving the local area with over 30 years of experience.
