About Karen

Karen Hartnett, a member of the Hardesty Team, began her real estate career in real estate conversion and development, the perfect foundation for real estate sales in Manhattan. After spending two years learning the fundamentals of Manhattan development, she was asked to join one of Manhattan's premier real estate brokerage companies where she immediately became a top broker in the city. Because of her sincere commitment to helping New Yorkers buy and sell their homes, she has maintained her position for over two decades. In addition to serving people in their endeavor to find a home, she has also worked within the industry to make it better. She has served on many committees, and she has the distinction of having been a director on the governing board of REBNY (the Real Estate Board of New York).

To her dedicated and ever-expanding private clientele, she brings this solid and diversified background. With her, they have the knowledge and comfort that they will be treated sensitively and professionally by one of the best brokers in the business and that their goal to buy or sell will be accomplished to the utmost of their satisfaction. It is a result of her commitment to have satisfied buyers and sellers that she has been the private broker of many of New York City’s most successful people and their families, serving every generation, siblings and friends with the same enthusiasm. As a result many of them have bought and sold with her several times. They continue to recommend her to their colleagues and friends.

In addition to her real estate career, Karen has spent a considerable amount of her private time as the NYC global and domestic leader for Results, with whom she has spent 16 years lobbying for the poor and where she has the distinction of participating in launching the first International Microcredit Summit. To expand her knowledge of the world she travels whenever she has the opportunity. When not traveling she enjoys the culture that is unique to Manhattan.
