What Altman Siegel does
Altman Siegel is a San Francisco-based contemporary art gallery and fine art consulting firm founded by Claudia Altman-Siegel in 2009. The gallery represented and exhibited internationally recognized, museum-level contemporary artists, cultivating a program that elevated significant Bay Area artists and introduced international artists to the San Francisco audience for the first time. Over 16 years, the gallery presented 213 exhibitions and art fairs.
The business operated two physical locations: a 5,000-square-foot flagship at Minnesota Street Project in Dogpatch (opened 2016) and a smaller Presidio Heights venue for more intimate presentations (opened 2024), following an original downtown space at 49 Geary. Revenue was generated primarily through transaction-based art sales to Bay Area collectors and institutional buyers (museums and significant collections), supplemented by fine art consulting services. Pricing was quote-based and not publicly disclosed; marketing relied on the gallery website, Instagram (@altmansiegel), exhibition openings, and a public exhibition archive on the Contemporary Art Library.
On November 22, 2025, the gallery announced its closure, with the founder stating that a gallery of its size had become too difficult to scale in the current market climate. Altman Siegel was privately held and founder-owned, with no disclosed institutional investors, funding rounds, or external capital backing.
