IEI General Contractors

What IEI General Contractors does

IEI General Contractors, Inc. is a privately held, founder-led commercial general contractor headquartered at 1725 Midway Road in De Pere, Wisconsin. Founded in February 1989 by Mike Johnson and Brad Deprez, the company has operated continuously as a member of the Associated General Contractors (AGC) of Wisconsin for over 35 years and serves project owners across northeastern Wisconsin. Its service portfolio is organized into five lines: Facility Maintenance, Additions/Renovations, Project Management, New Construction, and a Non-Profit Purchasing program, addressing the full lifecycle of a commercial building project.

The company's core technical differentiator is its self-performing model: in-house crews execute carpentry, masonry, concrete, demolition, casework, doors/frames/hardware, toilet partitions, and infection-control wall protection, reducing dependence on subcontractors and enabling tight cost and schedule control. This is paired with a formal safety program adapted from AGC of America Wisconsin Chapter Safety Policies and Procedures, OSHA 30-certified supervision, ICRA (Infection Control Risk Assessment) training, and weekly toolbox talks, supporting healthcare work in active facilities and yielding no lost-time injuries since 2008. Notable delivered projects include the $3M Bellin Health linear accelerator (2018), the ~$16M Prevea Health / HSHS St. Mary's multi-project program, the 78,000 sq ft Bellin Marinette clinic (2016), the 100,000 sq ft Cabela's in Ashwaubenon (2013), and the 100,000+ sq ft Associated Bank Corporate Office remodel.

IEI earns revenue through project-based, custom-quoted general contracting fees (no public pricing or subscription tiers), with anchor clients spanning healthcare systems (Bellin, Prevea, HSHS), K-12 and higher education (Red Smith, De Pere High School, Denmark High School, St. Norbert College), financial services (Associated Bank), retail chains (Menards, Cabela's), logistics (Schneider), government and utilities (Green Bay Metro Sewerage, Central Brown County Water Authority, Oneida One Stop), and religious/non-profit organizations. Distribution is direct and relationship-driven, with project flow sourced from owner relationships, architect referrals (e.g., Somerville, Nolan Carter), and AGC networking; a content blog, Facebook, LinkedIn, and Instagram presence support inbound demand, while pricing is bid per project on a multi-year contract basis.
