Martha Siwak - Real Estate Agent at Dielmann Sotheby's International Realty

Local Expertise. Global Connections.

Martha began her professional career in the jewelry department at Sotheby's Auction House in New York City. Working amongst some of the world's most esteemed works of art and luxury items while catering to the incomparable Sotheby's clientele, she learned the value and exceptional quality of the Sotheby's experience. With a background of 25 years in sales, she has found that real estate is the perfect career, combining her sales experience with her love of architecture and home interiors.

Having grown up in Clayton and Ladue and then ventured off to Hamilton College in Upstate New York, she has since found her home across the country in locales such as NYC, Boston, and Chicago. In addition to real estate, Martha has been an entrepreneur for over 14 years — she owns two start-ups focusing on manufacturing. Customer service, quality, and satisfaction have always been her #1 priority.

Additionally, Martha is the very proud mother of two young adult daughters making their way in the world and following in their mother's adventurous footsteps.
