"Amanda has represented our family in numerous real estate negotiations including the purchase and sale of three cooperative apartments in Manhattan, as well as the rental negotiations on a luxury property in Brooklyn. In addition to her work on our behalf, when my Father-in-Law needed to sell his Greenwich home, Amanda was our go-to resource. She helped to identify the perfect partner for a complex sale and was our coach and guide behind the scenes.

Amanda is a partner of the highest caliber--patient, creative and thoughtful, she navigates complex business negotiations and challenges with grace and grit. It is a true pleasure to work with her.

-Sarah Smart, Vice President Global Recruitment, Hilton


"Amanda has been my New York City real estate broker over the last five years. During this period, she has represented me in four transactions--one of which was my personal residence, the other three being business investments. Each and every deal Amanda and I have done together has been nothing less than stellar.

Amanda's expertise, knowledge, and spirit of collaboration allow me to sift through my impressions, wants and needs with maximum efficiency--helping me to arrive at an informed conclusion, the possibility of which I had often been unaware of previously. In addition, she is financially extremely practical, and I have always found her to be dialed into the mentality of the marketplace in a way that is rare in my experience. Amanda is timely, responsive and will go the extra mile. Above all, she has a type integrity on which I can rely.

I can recommend Amanda without reservation.

-John Seibert, President, Seibert Land Company & Seibert Cattle Company


"Amanda reported directly to me at Macklowe Properties’ 737 Park Avenue and 150 East 72nd Street, where she occupied the role of Senior Sales Associate.

Amanda was the highest producing sales agent on the team in terms of volume, but also on the basis of overall $PSF; additionally, she closed the largest deal in the building, at the highest price per square foot we achieved. Her success was directly related to several personal traits: her ability to understand and relate to prospective purchasers instinctively, her ease in identifying the priorities of those individuals—and lastly, her deep analytical knowledge of, and honed familiarity with, the product she was selling.

On a more personal note, Amanda is easy to work with, adaptable and dependable. Her hard-working and goal-oriented work ethic was very much appreciated by the entire Macklowe team.

I hope to work with her in the future.

-Dorothy Sexton, Senior Vice President of Sales, Macklowe Properties
