More About Michael


"Lisa and her team are so professional! She calls when she says she will. I appreciated her follow up every step along the way. She also walked me through a myriad of decisions, which I was nervous about since it was my first time to sell. Whenever I had questions or reached out to her, she and her team got back to me right away. I sold my place while living in another state, and I am grateful that she was able to be my eyes on the ground and advise me. The sale went very smoothly. Thank you, Lisa!"
"I am eager to tell you about my experience working with Lisa Maysonet. She was my broker when I sold my apartment on 66th Street in Manhattan. It was a difficult deal with lots of twists and turns and I believe that if I were working with another less experienced, less dedicated broker, the deal may have just fallen apart. Lisa is honest, very smart and she thinks outside the box to get the best deal for her clients. Lisa’s clients are not just a transaction for her. We are her people and that is why she works as hard as she does and has such loyal clients. In addition to all her skills listed above, Lisa is delightful to work with. I would call her immediately if /when I have a real estate need and I highly recommend Lisa and her team to anyone who is looking to buy or sell now or in the future."
"It is with much enthusiasm that I write to recommend the real estate services of Lisa Maysonet and Gary Kabol. I have known Lisa and Gary for more than 24+ years. Having originally met them when they sold our 9-room Park Avenue home and consequently sold us our townhome at 40 E 81st. 24 years later when it was time to sell that same townhome, we knew that the hard work, dedication, commitment and trustworthiness of Lisa and Gary would represent us in a dexterous manor. In addition to their skillful handling of the negotiations, their company's support at Sotheby's International Realty presented unbeatable reach which ended up securing us our out-of-town buyer. And thank you and Gary again for doing a bang-up job selling our house."
"The constant care for your needs made us feel we were more important than the sale of our apartment. We found that her character, energy and responsiveness made her the most professional and trustworthy broker we have come across."
"Group Maysonet stood by their word and did what they promised. Ms. Maysonet proved her professionalism and was able to deliver the results she promised."
"I have known Lisa Maysonet for several years from both a professional and personal perspective. She Lisa is hard working, articulate, intelligent and most of all, has high integrity. Lisa was able to provide guidance every step of our sale. Lisa demonstrated a commitment to us that I believe is rare in the industry, which further shows her dedication and professionalism. On a personal note, Lisa is funny, caring, and supportive."
