With more than a decade of experience in New York City real estate, Mary Hall Mayer has sold every type of property from co-ops, condos, and townhouses, to negotiating commercial leases. Her tenacity and work ethic have made her one of the most successful and well-respected agents in a very crowded field. Her work constantly stands out.

Mary’s continued excellent relationships with her domestic and international clients have consistently yielded both new and repeat business as well as referrals. Mary takes pride in being a straightforward, intelligent and honest agent. As she has said, I learned a long time ago that when working in a highly competitive industry in a highly competitive city, the most important elements for success are knowledge and focus plus determination and follow-through. Her positive and relentless energy is infectious and can guide any seller or buyer effortlessly through the process.

Mary has been negotiating and selling her entire career. She came to real estate following a stellar tenure in book publishing. As the former Director of International Publishing for Simon & Schuster, Inc., and as a literary agent who founded her own company in London and New York, Mary knows how to match the interests of multiple parties and bring those interests to a close.

Born and educated in the Midwest, Mary has traveled extensively in addition to living in England and the South of France. Even while living abroad, Mary never gave up her residence in New York. From homes on the Upper East Side, to a duplex at the Des Artistes, to a townhouse in the Village, Mary knows New York. She also knows what it means to buy, sell, and relocate internationally. Long an active shareholder in her lower Fifth Avenue co-op, Mary is very adept at helping both sellers and buyers through the co-op process. She speaks French fluently.
