Juliette R. Janssens

Juliette Janssens joined Sotheby's International Realty in 2004. She is a Senior Global Real Estate Advisor and Associate Broker. As a lifelong New Yorker with a passion for real estate, Juliette combines an exceptional knowledge of current market conditions with strategic, creative negotiating and marketing skills to best serve her clients.

Working in partnership with fellow broker, Allison Koffman, for over a decade, Juliette and Allison are able to provide their clientele with an invaluable wealth of knowledge and expertise in all areas of the Manhattan property market including co-ops, condominiums, townhouses, new developments and estates. They have access to a national and international network of Sotheby’s International Realty brokers to help facilitate transactions outside of the Manhattan area. Having sold in excess of $550,000,000.00 of property, Allison and Juliette are consistently ranked as top producers at Sotheby’s International Realty.

In 2014, Allison and Juliette were hired by Macklowe Properties to market the sell-out of the boutique development project, 150 East 72nd Street. In just over a year, they successfully sold out the project. This led to a second collaboration with Macklowe Properties at 737 Park Avenue, which they are currently marketing.

Juliette resides on the Upper East Side with her family.
