What Ronnette Riley Architect does
Ronnette Riley Architect is a privately held, 100% Woman-Owned Business Enterprise architecture and design firm founded in 1987 by Ronnette Riley and headquartered at 494 Eighth Avenue, Manhattan. The firm delivers professional services across four pillars: Architecture (adaptive reuse, new construction, resiliency, sustainability, Local Law 97 compliance), Interior Design (FF&E, infrastructure upgrades, systems design), Planning (feasibility studies, master planning, urban design), and Specialty Services (ADA accessibility consulting, code consulting, historic preservation, signage/wayfinding, expert witness work). Its practice is concentrated in the New York City public sector, where it serves agencies including FDNY, MTA, DCAS, NYCHA, SCA, and NYC Health+Hospitals, alongside universities (Columbia, SUNY, NYIT, Stony Brook, UVA), commercial brands (Apple, Coca-Cola, Restoration Hardware, Westin), and high-net-worth residential clients.
The firm has completed over 1,000 projects and holds 68 design awards, supported by an unusually deep certification portfolio (WBENC, MTA-DBE, DASNY, SUCF, NYC SCA, Port Authority of NY/NJ, multiple NJ agencies) that pre-qualifies it for set-aside public contracts. Service delivery is project-based, billed per engagement, and frequently executed in joint venture with tier-one partners (AECOM, Skanska, Stantec, HNTB, Rockwell Group, Rafael Viñoly Architects) on projects whose scale (up to 75,000 SF) exceeds what the firm's 20–30 staff could handle independently. Revenue is project-driven professional services income with multi-year contract cadences on public sector work; no SaaS, licensing, or recurring revenue streams are disclosed.
The firm has no external institutional investment, no parent company, and no subsidiaries. Leadership comprises Founder/Principal Ronnette Riley, Design Director Yumi Moriwaki (joined 2001, promoted 2019), Associate Steve Tsou (joined full-time 2017, promoted 2019), and Associate Slavica Nikolic (rejoined 2018, promoted 2019), reflecting a deliberate second-generation bench build-out. Growth signals are concentrated in NYC regulatory tailwinds (Local Law 97 decarbonization compliance) and incremental geographic broadening via joint ventures rather than aggressive M&A or platform expansion.
