What GH2 Architects does

GH2 Architects is a full-service architecture firm founded in 1973 and headquartered in Tulsa, Oklahoma, operating as a privately held LLC with 101-250 employees. The firm delivers architecture, interior design, landscape architecture, master planning, and a dedicated historic preservation practice (marketed as GH2 Preservation Architects) for clients across K-12 education, higher education, healthcare, municipal government, community/recreation, and hospitality sectors. Core technology comprises Building Information Modeling (BIM), CAD, and traditional design methodologies, with specialized expertise in LEED-certified high-performance building design (e.g., the Jenks Math & Science Center at LEED Gold and 30% above-baseline energy performance) and regulatory-driven preservation services including National Register nominations, Section 106 compliance, and historic preservation tax credit applications.

The firm secures work through enterprise B2B engagement via competitive bidding, RFP responses, and direct negotiation with institutional clients, generating project-based professional services fees on multi-year engagements. Notable contract scale includes the $130 million James Mountain Inhofe VA Medical Center (delivered in partnership with Leo A. Daly), a $110 million Muskogee Public Schools bond issue, and projects for clients such as Saint Francis Health System, Oklahoma City Public Schools, Jenks Public Schools, Northeastern State University, the City of Mesa, and Marriott International. GH2 is licensed in multiple states (Oklahoma, Arizona) and has expanded its footprint to Denver, Greater Phoenix, and project work in Montana.

GH2 maintains offices in Tulsa (with a relocation into a self-designed building in the Historic Greenwood District), Mesa (regional headquarters), Denver, and Phoenix (2026). The firm is privately held with no disclosed external investors, parent company, or funding rounds, and revenue is not publicly disclosed. Awards include AIA Eastern Oklahoma citations, IIDA Texas Oklahoma Chapter honors, ULI Oklahoma Impact Award, Arizona Forward Environmental Excellence Award, and the 2024 Arizona Preservation Foundation Governor's Heritage Honor Award, reflecting regional recognition rather than national prominence.
