  • My wife and I hired Ian to sell our co-op apartment on the Upper East Side. Ian has an excellent working style and is extremely focused and thorough. He does what he says he is going to do. He follows through, follows up and keeps in constant communication throughout the process. In the end, we received the purchase price we had hoped for and Ian was a big reason why. – Adam Mesh, Human Resources Executive

  • Ian expertly and patiently assisted my husband and I through the entire home buying process, from finding our apartment to completing the co-op board package and closing. Ian truly has a vast knowledge of the New York City real estate market and is a pleasure to work with. – Marisa Kodes, Legal Counsel, Alternative Investments

  • I was extremely happy with Ian's exceptional and detailed level of service, and his personable, can-do style of professionalism. He skillfully helped me sell my co-op apartment in Midtown and then found me a great new condominium just up the street. – Bill Imada, Chairman, Marketing/PR Firm

  • Ian's background work and canvassing made our first day of apartment viewings wildly productive. In fact, I ended up purchasing the second apartment we viewed, which I fell in love with on the spot. Ian was thorough in showing me numerous apartments beyond the one I chose, which only made my decision easier and my mindset stronger. – Deirdre Parker, Advertising Account Executive

  • Ian did a great job in working with us leasing our property in NYC. Once it came time for us to sell the condo, he was very good at implementing a successful strategy for us to maximize our value and working through the challenges of selling to a foreign buyer. – Asheshh Saheba, Architect

  • When a great opportunity turned up on the Upper West Side, Ian expertly advised us throughout the process. As first time home buyers it was important for my fiancé and I to work with a hands on broker. Ian was always transparent and dedicated to our goals. – Ramsey Peele, Corporate Accountant & Investor

  • As a first-time buyer of a co-op apartment in New York, Ian navigated me throughout the entire process. Always responsive, punctual and professional, Ian offers spot-on advice and sets the right expectations. – Eric Cheng, Software Designer, Internet

  • Ian was tireless in helping me find a wonderful new home. I was new to the process of buying a co-op and he walked me through every step of the way in great detail. It was a tough market but with his expertise and guidance, I found a great place that I truly love and plan on staying in for a long time. – Kelly Brandi, Technical Writer, Internet

  • After many negative and mediocre experiences with real-estate brokers, Ian proved to be exceptionally good.

Ian would be my first choice with any future real-estate search. – Uri Klein, Strategy Consultant
