Who We Are
Our Mission
At Kwasigroch Electric, Inc., our mission is to deliver exceptional electrical and low-voltage solutions with a steadfast commitment to quality, innovation, and customer satisfaction. We believe in building long-term relationships through hands-on management, integrity, and expert craftsmanship in every project we take on.
Who We Are
In electricity, business and life-timing is everything - 1989 was a pivotal year in many ways. Rich Daley served the first year of his record setting career as Chicago mayor. President George H.W. Bush took office. The Berlin Wall fell, and the Cold War ended. And a proposal for the start of something called the Worldwide Web was drawn up and submitted. Against that backdrop, in ‘89, a trustworthy south suburban native launched a business that would power and please thousands of satisfied customers for decades. Michael D. Kwasigroch (KWAHZ-ee-grow) opened the doors of a fair, honorable, and full electrical contracting business serving Chicagoland and beyond. His vision took root through the millennium and is now operated by a new generation of Kwasigrochs who carry forward his memory and his magnificent legacy of reliability and dependability. We look forward to meeting you and carefully addressing all your electrical needs.
