HOH Group

What HOH Group does

The HOH Group, Inc. is a privately held, full-service Architecture and Engineering (A/E) firm founded in 1959-1960 and headquartered in Schaumburg, Illinois, with additional offices in Indiana and Wisconsin. The firm operates as a Minority Owned (MBE/DBE) business following a 2019 acquisition by Santiago Garcia, under whose leadership headcount grew from 30 to 70 employees. HOH delivers five integrated service lines — Architecture, Civil Engineering, Structural Engineering, Mechanical Engineering, and Electrical Engineering — plus Construction Management, executed by in-house departments using Building Information Modeling (BIM) software for 3D visualization and virtual project walkthroughs prior to construction.

The firm's primary technology stack is BIM-centric, enabling unified design coordination across disciplines and supporting project delivery on transportation infrastructure (highways, tollways, bridges, rail), healthcare facilities, education campuses, industrial plants, and aviation projects. Notable engagements include the $62.75M ISTHA I-355 Veterans Memorial Tollway, a $50M LEED-certified Consolidated Rental Car Facility at Chicago Midway, an $20M O'Hare Maintenance Facility Expansion, a $40M Neal F. Simeon Career Academy, and industrial structural design for the $1.1B ATI Hot Rolling Processing Facility and $11.8B ThyssenKrupp Steel USA complex.

HOH generates revenue through fee-based professional services, billed on a project-by-project basis via competitive bidding for public-sector work and direct engagement for private clients. The go-to-market is relationship-driven enterprise field sales targeting Illinois Tollway, IDOT, Metra, CTA, City of Chicago, and Chicago Department of Aviation, supplemented by direct outreach to healthcare providers, universities, and industrial operators. Long-term blanket contracts (notably a $10M, 5-year Metra engagement) and Illinois Tollway GEC seats provide recurring revenue visibility, while IDOT, CDOT, CDB, and CMS prequalifications gate access to public-sector bidding opportunities.
