Erin Cullerton

Erin Cullerton

Founder + Chief Strategist

Erin has been helping creative brands successfully expand their marketplace visibility for nearly two decades. As the former Deputy Director and Director of Communications for the American Institute of Architects in San Francisco, Erin leverages extensive knowledge of the practice of design with established industry connections, deep media savvy, and proven best practices to position our clients for exposure to the right audience at the right time.

Through the years, Erin has launched numerous community engagement initiatives, including the successful Architecture and the City festival, the nation’s first month-long design festival, and most recently the Making LA conference. She has consulted on several national festivals, and garnered support for her efforts from the National Endowment for the Arts, Graham Foundation, and LEF Foundation. As a former journalist, her writing on design and culture has appeared in ARTnews, Metropolis, ReadyMade, Surface, Time Out London, and Wired, and she is the editor of the publications Contemporary Prefab Houses and Young Architects Americas.

Erin sits on the editorial advisory board of The Architect’s Newspaper and is a co-host of Design East of La Brea (or de LaB), an educational design nonprofit that has been known to throw some of the “best offbeat design experiences” in Los Angeles. She is an honorary member of the American Institute of Architects, San Francisco.

Erin’s favorite design object is the Petit Trianon light by Dutch designer Paula Arntzen, which she loves for its ingenious egg-like shape (made from paper, no less), and because it provides an opportunity for the eye to eat too.
