What Millies Engineering Group does
Millies Engineering Group is a privately held MEP-FP consulting engineering firm founded in 1975 by R. Lee Millies, Jr., headquartered in Munster, Indiana, with additional offices in Chicago, Illinois and Grand Rapids, Michigan. The firm provides integrated mechanical, electrical, plumbing, and fire protection design services, supplemented by LEED AP design, construction administration, commissioning (with CPMP-certified staff), lighting design, energy assessments and audits, telecom design and wireless modeling, CADD/4D BIM, power distribution design, and sustainability/energy modeling. Underlying technology centers on CADD computer-aided design and 4D Building Information Modeling for collaborative design-to-construction processes, alongside a proprietary 'More Th(ink)' documentation methodology designed to reduce construction-phase communication errors.
The firm serves architects, building owners, and facility managers across seven verticals: Education (primary), Healthcare (primary), Commercial (primary), Community/Municipal, Recreational, Religious, and Historic preservation. Notable projects include Beacon Granger Hospital, the $25 million Wallin Oaks Elementary School, the $23.5 million Hanover upper elementary school, the $21 million Bloom Township High School Art Deco HVAC renovation, the Liberty Tower residential redevelopment in South Bend, and the AIA-nominated Berrien Springs performing arts facility. The firm holds LEED AP, CPMP, ASHRAE, and AEE certifications, employs licensed engineers in 45 states, and collaborates with a deep network of architectural partners including Shive-Hattery, SGW, Aria Group, Moss Design, and others.
Millies generates revenue through project-based professional services engagements with bespoke, scope-specific pricing (no public rate cards). The go-to-market is sales-led, primarily through direct relationships with architects and facility owners, supplemented by referral-driven partnerships with architectural firms and limited inbound via website, blog, LinkedIn, and Instagram channels. The firm is independently owned and operated, with no disclosed external investment, and has completed over 5,000-8,000 projects since 1975, earning consecutive 'Best Engineering Firm in Northwest Indiana' recognition and a 2016 American Planning Association 'Best Public Spaces' award.
