Since 2006, Greenfield-Sanders has produced 24 etchings with longtime collaborators Paulson Fontaine Press.

In 2014 Greenfield-Sanders’ etching “Pikes Peak” won the PRIX DE PRINT awarded by Art in Print Magazine juried by Gill Saunders, head of prints of the Victoria and Albert Museum in London.  That print was added to the museum’s collection shortly thereafter.

Greenfield-Sanders’ etchings are collected both privately and publicly.  Both the Fine Arts Museums of San Francisco and The Museum of Fine Arts Houston have large portfolios in their permanent collections.
