Founded in 1990 by Tom Wissehr, Wissehr Electrical Contractors began as a small specialty electrical contractor that focused on service work for industrial clients and traffic signal construction.  Through the years, we’ve grown into other markets and gained a reputation for expertly managing and completing the most complex commercial, industrial, and transportation projects — with schedules, deadlines, budgets, and parameters that no one else wants to tackle. Yet we prevail because of our can-do attitude, innovative thinking, expertise, and discipline.

Our clients trust us to perform well on a variety of project challenges, and we respond with the same urgency and care for each one. We understand their success often hinges on our performance. If it’s important to our clients, it’s important to us and we’re ready to help.

We thrive on the tough ones.

We’ve tackled the most challenging electrical contracting projects and succeeded by combining sound engineering, creative thinking and strict attention to safety. Because we self-perform our work, our professional engineers and talented office, maintenance and warehouse employees handle every phase, taking personal responsibility as a valued team member.
