Oakstreet Art Conservation



Based mid-Peninsula in the San Francisco Bay Area, Oakstreet Art Conservation provides world-class art conservation and restoration services specializing in 3-dimensional decorative arts, with emphasis on furniture, wooden objects, and Asian lacquer. The studio has experience treating a wide variety of materials, including ceramics, glass, decorative metals and stones, wood, animal-based materials (ivory, coral, turtle-shell, mother-of-pearl, bone, leather), gilding, and painted and varnished surfaces. 


Oakstreet primarily serves West Coast private collectors, institutions, art dealers, and auction houses. The company is owned by Catherine Coueignoux, who has over 20 years of experience working, doing research, and teaching in museums and private labs in the US, Europe, and Asia.

In addition to treatment, services provided include collections care and surveys; condition reports; sampling; and installation, exhibition, and transport support. Oakstreet also undertakes consultancy and teaching projects, which have included work sponsored by the World Monuments Fund (WMF) in the Forbidden City, Beijing; and by the Foundation for the American Institute of Conservation of Historic and Artistic Works (FAIC) on the East Coast.

All treatments are carried out in accordance with the American Institute of Conservation of Historic and Artistic Works (AIC) Code of Ethics and Guidelines for Practice.
