Mission Critical Group (MCG), a critical power infrastructure company specializing in the design, manufacturing, delivery, and service of advanced electrical systems, has announced the acquisition of Leman Engineering and Consulting (LEC), a Brookston, IN-based manufacturer of switchgear, control systems, and power distribution equipment.
The acquisition strengthens MCG's Midwest manufacturing presence, expands its engineering capabilities, and establishes LEC as MCG's R&D hub for power generation engineering. This hub focuses on switchgear innovation for onsite generation, prime power, generator paralleling, behind-the-meter systems, and microgrids.
"LEC has exceptional people and a proven record of quality and innovation," said Jeff Drees, CEO of Mission Critical Group. "By bringing best-in-class companies like LEC into our portfolio, we are strengthening every layer of the power distribution chain, from engineering and manufacturing to service and field execution, and advancing our ability to deliver resilient, U.S.-based power infrastructure."
With expertise in prime power distribution design, precision manufacturing, and engineering, LEC strengthens MCG's unified power and energy infrastructure platform, delivering high-performance electrical solutions across data center, healthcare, industrial, oil and gas, and other critical markets. Its capabilities in UL 891 switchboards, UL 1558 switchgear, and medium-voltage equipment further expand MCG's technical depth and manufacturing reach.
The establishment of MCG's R&D hub will also align with strategic university partnerships specializing in power engineering, further advancing innovation and workforce development across the electrical manufacturing sector.
"We are proud to join MCG and contribute to its continued growth and innovation," said Randy Leman, President of Leman Engineering and Consulting.
Leman will now serve as Vice President of Engineering and Product Management for Electrical Equipment at MCG. The Indiana team will continue operating under existing leadership, maintaining its strong local presence and customer focus.
