What Garmann/Miller Architects-Engineers does

Garmann/Miller Architects-Engineers is a privately held, multi-discipline architecture and engineering firm founded in 1993 and headquartered in Minster, Ohio. The firm delivers integrated architecture, interior design, mechanical/electrical/plumbing (MEP) engineering, civil engineering, landscape architecture, and technology design services from a single in-house bench of 100+ professionals, reducing reliance on external subcontractors and enabling one-firm delivery for complex public-sector projects.

The firm operates across offices in Minster, Columbus, Celina, and Cleveland, Ohio, plus Fort Wayne, Indiana, with active project footprints extending into Pennsylvania, Maryland, and Delaware. Its core technology stack is built around BIM/REVIT-based design and 3D visualization, supporting documentation, coordination, and owner presentation workflows typical of mid-sized A&E practices.

The business model is project-based professional services revenue, driven primarily by K-12 education clients (school district capital programs, renovations, and new builds), with supplemental work in civic/municipal, healthcare, industrial/commercial, and faith-based markets. The firm is family-owned, with founder Bruce Miller and son Ben Miller on the board and Eric Baltzell serving as CEO since 2017 and Chris Monnin as COO. Revenue is not publicly disclosed, and the firm has not raised institutional capital or executed disclosed acquisitions.
