What Treanor does

Treanor is a privately-held national architecture firm founded in 1981 in Lawrence, Kansas by Michael Treanor. The firm operates 12 offices across the United States and delivers architecture, planning, interior design, civil and landscape engineering, laboratory and medical planning, and historic preservation services. Work is organized into eight sector-specific studios — Advanced Industries, Health, Higher Education, Historic Preservation, Housing, Justice, PK-12 Education, and Site Planning — that serve government agencies, healthcare systems, higher education institutions, K-12 school districts, and private sector clients. The firm has grown through a documented sequence of mergers and acquisitions (GLPM in 2008, H+L Architecture and Carey & Co. in 2016, Hug & Associates in 2018, The Stinnett Group in 2021, McCoy Collaborative Preservation Architecture in 2023) and rebranded from TreanorHL to Treanor in 2024 to consolidate its acquired entities under a unified brand.

Revenue is generated through professional services fees on custom-quoted, project-based engagements — architecture services priced per project depending on type, size, complexity, and scope, with multi-year contract durations typical for institutional and government work. Go-to-market is relationship-driven and principal-led, leveraging direct engagement, visioning workshops, design charrettes, and consensus-building processes suited to public-sector and institutional procurement. Domain differentiation rests on codified expertise in regulated and technically demanding project types — trauma-informed justice and behavioral-health design, SCIF and secure-facility design, healthcare facility planning, and historic preservation under the Secretary of the Interior's Standards — supported by credentials including LEED, Zero Net Energy, WELL, and AIA 2030 Commitment.

Customer logos span defense and aerospace primes (Lockheed Martin, BAE Systems, Northrop Grumman), national healthcare systems (Stanford Health Care, Children's Hospital Colorado), higher education clients (University of North Texas Health Science Center), and state and local government (State of California DGS, Douglas County Kansas). Recent strategic activity includes the 2025 Houston office opening, sustained tuck-in M&A, annual leadership promotion cycles, and industry recognition including 2026 ENR Midwest Design Firm of the Year and Zweig Best Firm to Work For. The firm does not publicly disclose revenue or financial metrics, and headcount is reported as a band of 101–250 employees.
