What Garmann Miller does

Garmann Miller is a privately held, multi-service architecture, engineering, and design firm headquartered in Minster, Ohio, founded in 1993 by Bruce Miller on three guiding principles: provide exceptional service, create quality design, and do what's right. The firm operates as an integrated platform providing architecture, civil engineering, electrical engineering, mechanical engineering, interior design, landscape architecture, construction administration, survey services, BIM/3D visualization, and project funding assistance under a single multi-service framework. It is led by CEO Eric Baltzell (appointed 2017) and COO Chris Monnin, with a distributed principal/board structure including founder's son Ben Miller, who heads business development. The firm is recognized by Zweig Group as the No. 1 full-service firm in the U.S. (2020), a Building Design + Construction and Engineering News Record national Top 100 firm, ranked No. 13 globally by the U.S. Green Building Council for LEED K-12 project administrators, and a five-time Best Firms to Work For awardee.

The firm's go-to-market is sales-led and relationship-driven, organized around regional business development leads for Ohio K-12, Indiana K-12, Mid-Atlantic K-12, and Pennsylvania, supported by participation in Ohio School Boards Association, Indiana School Boards Association, and SMPS events. Its customer base is concentrated in the K-12 education vertical (school districts pursuing new construction, renovations, athletic facilities, and career-technical centers), with secondary exposure to community/civic, commercial, higher education, healthcare, faith-based, industrial, and parks and recreation markets. Revenue is generated through project-based professional services fees, with no public pricing disclosure. The firm serves clients through nine offices across Ohio (Minster, Columbus, Cleveland, Celina), Indiana (Fort Wayne, Carmel), Maryland (Owings Mills), Delaware (Newark), and Pennsylvania (Lancaster), and grew geographically through the 2020 Indiana entry — established via partnerships with Studio M Architecture & Planning and Hoch Associates — and the 2023 acquisition of Access Engineering Solutions, which expanded in-house civil engineering and survey capabilities.
