Juliette R. Janssens

A lifelong New Yorker with a true passion for real estate, Juliette Janssens is a Senior Global Real Estate Advisor and Associate Broker who uses her exceptional knowledge and creative negotiating and marketing skills to help clients realize their dreams. To her, a home is more than an investment—it’s a vital part of a person’s well-being.

Juliette attended the Johns Hopkins University and the University of Colorado and has a background in fashion and publishing. She traveled and lived in locations across the country before returning to New York, putting her keen eye for style, her deep Manhattan roots, and her love of real estate to work. She joined Sotheby’s International Realty in 2004 and quickly established a reputation for comprehensive market knowledge, sharp analytical skills, and dedication to the industry and her city. Clients and colleagues alike admire her open and honest communication, patience, and discretion.

For more than a decade, Juliette has partnered with fellow broker Allison Koffman. Their business acumen, discernment, in-depth familiarity with the city’s neighborhoods, and sophisticated marketing materials set them apart. Their expertise covers all areas of Manhattan, and their understanding of the nuances of New York real estate allows them to help clients navigate that daunting world with ease. In addition to working with buyers and sellers, they have successfully represented new development projects on the Upper East Side, providing them with unique insights that expedite successful deals. Their trusted partners in other markets facilitate transactions outside the Manhattan area. Juliette and Allison are consistently ranked as top producers at Sotheby’s International Realty, with over a billion in sales.
