Sikes Abernathie Architects

What Sikes Abernathie Architects does

Sikes Abernathie Architects is a privately held professional architecture firm founded in 1994 and headquartered in Tulsa, Oklahoma. The firm provides architectural design services across four core service lines: multi-family housing (both market-rate and affordable), historic rehabilitation leveraging historic tax credits, adaptive reuse of existing structures, and commercial building development including master planning and mixed-use projects. It serves real estate developers, tribal and municipal governments, and institutional clients such as the University of Oklahoma Institute, with a documented portfolio of 70+ completed projects spanning values from roughly $1.5M to $43M.

The firm operates as a traditional professional services practice without proprietary software, platforms, or technology products; its competitive differentiation rests on multi-state licensure (17 U.S. states across the Midwest, South Central, and Mountain West), decades of accumulated expertise in historic preservation and adaptive reuse, and brand recognition anchored by landmark Cherokee Nation restorations. Leadership consists of founding partners Mike Sikes (President) and Mike Abernathie (Vice President), both licensed architects.

Revenue is generated exclusively through project-based architectural fees billed to clients across multi-family, historic rehabilitation, adaptive reuse, and commercial segments. Go-to-market is direct enterprise engagement with developers from concept to completion, supplemented by a website portfolio and limited social media presence. The firm maintains no disclosed parent company, no institutional investment, and no public funding history; ownership is partnership-based and the company has operated continuously for over 30 years with active projects scheduled for completion through 2027.
