Real Estate Agent

A Manhattan native, Leslie O’Shea works with a diverse range of clients, including individuals, investors, developers, family offices and non-profits. She has represented a major cultural institution in Manhattan, and was also appointed by a Federal Judge to liquidate a Park Avenue cooperative. Leslie creates sophisticated deal structures and presents complex financials with clarity.


“I place C-suite executives and board directors for large corporations. Leslie has been my agent in three transactions, and I have referred several of my friends, clients and colleagues to her. I trust her to be intelligent, professional, discreet and straightforward.”


“I am an executive vice president and account director at a global advertising agency. I am pleased to provide a reference for Leslie O’Shea, who handled the sale of my Upper West Side apartment. I was impressed with the insights from her own background in advertising and marketing. She also knows how to deliver attentive client service. Her consistent and detailed communication helped smooth the process for me.”


“My wife and I listed our penthouse apartment with Leslie. She worked with alacrity to present the apartment in an attractive way, arranging staging of the interior and magazine quality photography. She presented the building itself with sophistication, drawing on her deep knowledge of the competing properties. We received multiple offers.”

“When I needed to sell my aunt’s Park Avenue apartment, I sought advice from one of the owners of an international real estate development firm. He recommended Leslie O’Shea. She priced the apartment correctly and gave me great advice, including telling me to turn down weak offers. I have had a long career in luxury real estate and I cannot recommend Leslie more highly.”
