Knobelsdorff

Knobelsdorff is a trusted industrial electrical contractor providing top-notch automation and controls, electrical, engineering, renewable energy, and power services nationwide. 

In early 2025, Knobelsdorff opened a new office in Oglesby, Illinois! This expansion strengthens our ability to serve customers and grow in the region. We’re excited to build new connections and keep moving forward. We’re also expanding our Operation Trades Awareness (OTA) program, bringing more opportunities to the next generation of skilled trades in Illinois.
 

Knobelsdorff started over 35 years ago in a small garage, founded on a simple but powerful commitment: to deliver reliable, high-quality electrical services to our local community. What began as a small operation has grown into a multifaceted company with four divisions, projects across the nation, and a presence that reaches even beyond our national borders. Despite our growth, we’ve never lost sight of what got us here—hard work, dedication, and a relentless focus on getting the job done right.
 

Our journey from a small electrical company to a national leader is a testament to our core values – Safety, People, Passion and Performance. We’ve built a reputation for excellence, not just through the projects we complete but through the relationships we build. At Knobelsdorff, every role matters, every project is meaningful, and every customer partnership is valued. We’re a team that takes pride in our work, ensuring that we meet the highest standards of quality and safety on every job, every time.
