Sebastian Sarmiento
Founder, Partner
Sebastian founded SANSAR in 2020 while serving as a Director at the storied Marlborough Gallery in New York, a position he held for 11 years. While at Marlborough, he played a pivotal role in nurturing and maintaining relationships with prominent artists, estates, and collectors. In addition to overseeing the curation and production of major exhibitions—both at the gallery and beyond—Sebastian facilitated numerous complex, multi-million-dollar acquisitions for clients, artists, and museums.
Born in Venezuela, he attended Bard College in New York’s Hudson Valley, where he studied art history and began exploring the Latin American market. Today, he counts many of the leading figures in Latin American art among his closest contacts and maintains extensive relationships with major galleries and auction houses worldwide. His expertise spans both the primary and secondary art markets, and he is particularly experienced in all aspects of monumental sculpture, having placed, installed, and maintained numerous works in major collections around the globe. Sebastian travels frequently to art fairs and exhibitions throughout the year, and divides his time between Manhattan and Columbia County, New York.
