Shamrock Electric

Shamrock Electric Co, Inc. is a family-owned business that has been providing dependable services in the Chicago area since 1957. Founded by brothers Jack and Bill O'Shea, the company started as a commercial and industrial contracting company and has since grown into a trusted full-service electrical contracting firm. Our first office was located in the north side Chicago neighborhood where the O'Sheas grew up. As the company expanded, we relocated to a new headquarters in suburban Elk Grove Village.

Throughout our history, Shamrock Electric has consistently seized opportunities to respond to market needs. We have expanded into the booming residential construction market, honed our design-build skills with challenging new projects, and adopted new, green technologies. Today, we offer a complete range of services including LEED projects, Life Safety Installations, Renewable Energy Installations, and Structured Cabling. Our commitment to innovation and technological expertise in electrical contracting delivers higher quality projects.
