Agency Sotheby's International Realty - East Side Manhattan Brokerage


Kathy Steinberg’s love of the business is inspiring and energizing. She began her real estate career in 1994 and soon developed a reputation as “wonder woman,” a straight shooter, and a top broker. She is recognized for her expertise, confidence, vigilance, personal responsibility, and attention to detail.

Kathy understands the dynamics and nuances of cooperatives, specializing in prewar Upper East Side buildings. She is extremely well connected and is known for representing some of the most important properties in the city, handling numerous significant sales. Her most spectacular record-breaking transaction was the former Rockefeller duplex apartment at 740 Park Avenue, during which she represented both the buyer and the seller. Another of her many outstanding sales was an apartment at 834 Fifth Avenue, which sold in less than two weeks for more than $10 million over the asking price.

For Kathy, levity and a sense of humor are essential. She understands people well, values their time, and quickly comprehends their priorities, needs, desires, and goals. Widely admired for her honesty, candor, and absolute discretion, she is respected by her clients and establishes close, long-lasting relationships them. Her trusted professional relationships contribute to a consistent record of brokering top sales and garnering repeat referral business.

Kathy grew up in Lawrence, on the south shore of Long Island, and has lived in Manhattan her entire adult life. She loves the energy, vibrancy, and culture of the city—the theater, on and off Broadway; Carnegie Hall; the opera; movies; and the multiple choices of great dining experiences all over town. Her passion for travel has taken her all over the world, sightseeing, biking, and hiking, including a climb up Mt. Kilimanjaro. She is an Advisory Director at Carnegie Hall and has served in the Education Program at the Metropolitan Museum of Art.
