What Lemberg does

Lemberg Electric Company, Inc. is a 100% employee-owned (ESOP) electrical contractor founded in 1928 and headquartered in Brookfield, Wisconsin. The company operates across five integrated service divisions: Electrical Construction (design-build, preconstruction, VDC/BIM, prefabrication), Electrical Services (24-hour emergency response, preventive maintenance, infrared thermography, arc flash analysis), Data Communications (structured cabling, life safety, fire alarm, building automation), Custom Business Signs (design, fabrication, installation, digital and ADA-compliant signage), and Energy Technology (photovoltaic solar, LED retrofits, EV charging stations). Delivery is enabled by Accubid, CAD MEP, Building Information Modeling (BIM), and a proprietary registered trademark, Agile Construction®, used as a project management methodology. Lemberg's customers are enterprise and mid-market commercial, industrial, and healthcare facility operators across Milwaukee and southeastern Wisconsin, with named clients including Froedtert & the Medical College of Wisconsin, Children's Hospital, Harley-Davidson, IKEA, Fleet Farm, Milwaukee Bucks, and Associated Bank.

The company generates revenue through professional-services project contracts (new construction, design-build, and installation) plus ongoing service and maintenance contracts, with quote-based pricing on a per-project basis and no publicly disclosed rates. Go-to-market is exclusively direct enterprise field sales targeting southeastern Wisconsin, supplemented by website quote requests and a 24/7 emergency service line. All field electricians are IBEW Local 494 union members trained through the Milwaukee Electrical Joint Apprenticeship Training Committee, and the company maintains specialized certifications including ICRA (for healthcare environments), NFPA 70E/70B, and OSHA 10/30. In-house prefabrication is supported by a 48,000 sq ft headquarters that includes a 7,600 sq ft dedicated training facility.

Lemberg's growth strategy has emphasized capability expansion over geographic expansion: acquisitions of So-Lite Neon (2009) and Good Electric (2010) extended the signs and Waukesha service footprints; photovoltaic market entry (2008) launched the Energy Technology division; and the 2022 preconstruction/VDC expansion with a collaborative design space deepened front-end project participation. The company has earned industry recognition including the 2024 NECA Project Excellence Award, repeated Wisconsin Sign Association first-place wins, three consecutive MMAC/COSBE Future 50 honors (2017-2019) with a Master Mettle Award, and Focus on Energy Platinum Trade Ally status.
