My passion is midcentury mosaic; as a researcher, maker and photographer I have accumulated an inventory of thousands of images, both decorative and architectural. Over the past 20 years I’ve traveled widely to build relationships to access many rare archives of mosaicists’ private works. This detective work takes a long-term commitment to the genre, and that’s why clients have referred to me as “Columbo” and “Miss Marble”


I have a keen eye to uncover tell-tale clues that can assist identification, the small details that can be lost to those who are not trained in mosaic. I work professionally providing contextual evaluation and technical analysis of mosaic works, which can reveal not only value, but a worth—a mosaic DNA—which is of great value to the collector and to the legacy to the history of American art and craft.
