From July 2006 – March 2011, Triple Base was co-curated and co-directed by Joyce Grimm and Dina Pugh. Grimm and Pugh co-created the gallery’s mission and its subsequent exhibitions and programs through March 31, 2011. Under their direction, Triple Base remained close to the original intent of the founding artists’ diverse exhibition programming and artist-centered mission but with increased accessibility, visibility and number of artists and audiences served.

In November of 2006, four curators attending graduate school at California College of the Arts were invited by co-founder Oliver Halsman Rosenberg to take over the space. Joyce Grimm, Dina Pugh, Nancy Meyer, and Audrey Marrs, formed the curatorial collective, No. 4 to develop and execute six months of exhibition programming at Triple Base.

In 2006, Rosenberg moved to New York and Taniguchi moved to Tokyo and currently co-directs a sister gallery space, Nakaochiai Gallery. The gallery provides free, non-commercial events and exchanges to a growing network of international artistic communities. The two artists continue to work together and were featured in the exhibition Instant Drawing Machine at The Drawing Center, New York. Link to Oliver Halsman Rosenberg’s blog

In 2003, artists Clint Taniguchi and Oliver Halsman Rosenberg established Triple Base located on 24th Street in the Mission District of San Francisco where they promoted the artistic endeavors of many local artists and conducted community-engaged projects. The space operated organically, suiting the needs of whatever artistic expression was appropriate for the time.
