Mithun

What Mithun does

Mithun is an integrated design firm founded in 1949 by University of Washington professor Omer Mithun and headquartered in Seattle, Washington. The firm operates three offices (Seattle, San Francisco, Los Angeles) with 200+ employees and delivers architecture, interior design, landscape architecture, and urban design and planning services. Its client base spans higher education, housing, cultural/civic, corporate/tech, and government segments, with named clients including the University of Washington, UCLA, UC Irvine, Microsoft, Google, Atlassian, Weyerhaeuser, Security Properties, Mission Housing, Denver Housing Authority, and Miraval Resorts.

The firm’s revenue model is project-based professional services, with more than 80% of work sourced from repeat clients, reflecting long-cycle institutional relationships rather than transactional bidding. Mithun has operated as a carbon-neutral practice since 2004, holds an ILFI JUST Label, and has earned nine AIA Committee on the Environment (COTE) Top Ten Awards — credentials that materially differentiate the firm on sustainability-mandated procurements. An internal R&D program targets Artificial Intelligence, Carbon, Construction Technology, Health and Wellbeing, and Resilience, producing proprietary tools such as a Mass Timber Schools Kit-of-Parts, Build Carbon Neutral Calculator, Heads Up Display Dashboard, Façade Generator, and Middle Housing Playbook.

Growth has been augmented through M&A and geographic expansion: the firm merged with Daniel Solomon Design Partners in 2012 and acquired Schacht Aslani Architects in 2019, adding urban design and design-build depth; it opened San Francisco in 2008 and Los Angeles in 2018. Leadership includes President Dave Goldberg and Partners Anne Torney, Brendan Connolly, Craig Curtis, and Debra Guenther. Recent recognition includes 2025 awards (AIA COTE Top Ten for Bush School, AIA Washington Civic Design Merit, PCBC Gold Nugget, NAIOP Oregon Mixed Use of the Year) and 2026 awards (AIA COTE Top Ten for Kapuso at the Upper Yard, DJC Oregon Top Project), confirming active operating momentum.
