Before joining Heritage, Tracy originally hailed from the Buffalo, New York area and was working toward a BA in Art History at SUNY Buffalo before she was given an opportunity to start her career in Jewelry at Sotheby’s in NYC. Over 22 years, Tracy developed her expertise in jewelry while heading various departments. As an auctioneer, she proudly auctioned the estates of Ella Fitzgerald and George Burns among others, and was an integral player for the jewelry in auctions for the Duchess of Windsor, Andy Warhol and Jackie Kennedy Onassis while at Sotheby’s.  Tracy left Sotheby’s to open her own jewelry brokerage business and do what she loves — helping clients refine their collections by adding to them or selling their unworn or unwanted pieces. Among her accomplishment, she spearheaded the sale of the estate of Marge Kelly’s jewelry collection at public auction for $8 million. In addition, she opened and ran a Palm Beach buying office for a New York firm (CIRCA) for six years.  For the past four years, Tracy has returned to run her own business in Palm Beach, assisting clients in all areas of art and antique collecting, whether through formal appraisals, buying or selling, and using her network of allied professionals and collectors to achieve the best financial outcome for her clients. Additionally, she is USPAP certified to ensure compliance with today’s insurance and IRS requirements.
