Established in 1911, Douglas Elliman Real Estate today has the distinction of being the largest regional real estate firm and the fourth largest in the United States. It is New York’s largest residential brokerage, with over 70 offices in New York City, Long Island, the HamptonsWestchester/Putnam, and South Florida, including a strategic partnership with London-based Knight Frank LLP for residential business in all of its New York markets. With a complete suite of real estate services—from sales and rentals, to mortgage (through DE Capital Mortgage), new developments, and title services—the company has experts in every field to guide clients skillfully from the beginning to end of their real estate journey.

Behind the impressive statistics is a powerful network of more than 4,000 agents—top talent like experienced Westchester realtor Lisa Koh. Licensed since 1988, Koh started selling real estate in Westchester in 1999, quickly building a reputation in the industry as highly successful, effective, and a consistent recipient of Douglas Elliman’s Top Producer Award. Born and raised in Northern Westchester, she has been able to guide clients through the buying and selling process with her deep knowledge and well-earned confidence. Although she will cover any area in which her clients have an interest, Koh’s primary areas of focus include Armonk, Pleasantville, Bedford, Mt. Kisco, and Pound Ridge, particularly the Byram Hills and Bedford Central School districts.

Driven by a tenacity and laser-sharp focus on her clients’ needs, Koh says, “I’ve always had a passion for beautiful properties. What I enjoy most about my profession is finding the perfect property to match my clients’ needs and desires.”

Over the years, Koh has represented a wealth of beautiful properties. Most recently, she sold the 6.2-acre estate known as Waterbury Farm for $5.2 million. The historic 1929 property was once home to many famous past owners, including Wall Street broker Theodore Bernstein and wife costume designer Aline Bernstein, who co-founded The Costume Institute at the Metropolitan Museum of Art. Distinguished by restored architectural details and high-end amenities, the estate’s 8,900 square-foot English stone manor features six bedrooms, six full baths, two powder rooms, a pool, and pool house.

Among the distinctive properties Koh currently represents is a stunning 8,041 square-foot waterfront Colonial in Armonk’s prestigious Windmill Farm at 14 North Lake Road that Koh describes as “a hassle-free alternative to the Hamptons lifestyle.” On the market for $4.95 million, the property features five bedrooms, seven baths, two powder rooms, a Christopher Peacock gourmet kitchen with state-of-the-art appliances, a master suite with a spacious spa-like master bath, a walkout lower level, and a massive stone patio. The home’s open floor plan, easy flow, water views, and private lake access make it a natural for entertaining. The unique setting also includes a private dock—a perfect spot for winding down and relaxing.
