As a generalist I appraise fine art, antiques and household contents. I also hold a certification specialty from AAA in Silver. I continually build on my appraisal experience and education by attending conferences, classes, and auctions. My initial experience in this field began when I lived in England where I completed a Diploma Course from the Royal Academy of Fine Arts. After my return to the United States I began working with a local appraiser completing estate, insurance and donation appraisals specifically dealing with English antiques, fine art and silver. For the last 20 years, I have been involved in my own appraisal practice. My clients include insurance agents, lawyers, and accountants from Connecticut and Westchester County.
