Estria Miyashiro

Co-Founder / Executive Director

Estria Miyashiro has been spray painting for over 30 years, and is recognized around the world as an urban art living legend. As a pioneer in an arts movement that is arguably more influential than the classical renaissance, he is acknowledged as a valued historian, and also a community leader who is helping to awaken the social and political consciousness of graffiti writing art.

Originally from Honolulu, Estria moved to The Bay Area in the 1980’s during San Francisco’s “Golden Age Of Graffiti.” His murals are known to be fun, cultural, political, and vibrant, with a focus and dedication to uplift the communities they serve. His graffiti art background has led him to produce innovative projects as an educator, entrepreneur, and social activist. From the city streets, to executive suites, Estria has worked with numerous non-profit organizations (Precita Eyes Mural Arts Center in San Francisco & Eastside Arts Alliance in Oakland), as well as high profile corporations. In 2007, he co-founded the “Estria Battle”, a nationwide urban art competition that honors and advances creativity in the Hip Hop arts. In 2010, he co-founded the Estria Foundation.

Guy Nakashima

Fundraising Director

With over a decade of professional fundraising experience, Guy has successfully raised millions of dollars for mission-critical programs and projects throughout the Hawaiian Islands. Guy holds an M.A. in political science from the University of Hawai‘i at Mānoa where his studies focused on public policy. During graduate school, Guy interned at the Hawai‘i State Legislature and later worked as a Committee Clerk for House of Representative’s Committee on Education chair Roy Takumi.

Since his time at the Legislature, Guy has served as the Director of Foundation and Relations at the National Tropical Botanical Garden, the Assistant Executive Director at Hi‘ipaka LLC, the Associate Executive Director of Advancement at the Hawaiian Islands Land Trust and most recently as President of Grant Works Hawai‘i.

Outside of the office, Guy spends his free time with his kids at the park watching them play competitive softball and soccer.

Mike Bam Tyau

Project Manager / Muralist

Born and raised in Honolulu, Mike “Bam” Tyau currently resides in the San Francisco Bay Area, but returns often to Hawai‘i to teach mural and Hawaiian cultural classes for the Mele Murals program.

Mike started his career in the videogame industry working for Sega of America and climbed the corporate ladder to become an art director in graphic design. He started a computer animation company and his past computer graphics work affects how he uses technology in his artwork today. Mike has collaborated with other artists in New York City, Miami, Hiroshima, Barcelona, Florence, and frequently returns to Honolulu to teach and paint for Mele Murals.
