  • “The process of relocating from Malibu CA to Longboat Key was an often daunting process trying to understand the nuances of our future home and an unknown neighborhood. Synchronic to finding the perfect home we found the perfect professional in Mr. Mark Baron. He listens close to what his clients ask for and focuses astutely to present the ideal options. He communicates clearly and understands the market, the trends and has excellent vision of Real Estate potential. We highly recommend Mark and know our move turned out better thanks to him.”

  • Congrats to you as well. You put a lot of time and effort in to help make this sale happen. You were great to work with over the past year on recommending strategic improvements that didn’t break the bank. Lastly, your skill during the negotiation phase was excellent. Thank you very much, hope you have a great weekend…it is well deserved.

    Scott G. (Seller)

  • “I had the great pleasure of working with Mark Baron over the past six months as we prepared for and successfully sold our parent’s winter residence on Longboat Key. Through an acquaintance here in Vermont and via your real estate network I was told to await a call from “an agent”. I had no idea what to expect and no knowledge of Florida real estate. At every step of the way in what could has been a daunting process, Mark made things seem straightforward and easy. He seemed to be always available, with sound advice, clear instructions about next steps, and the patience to listen to his client’s sometimes tangential ramblings. For over fifty years I have taken pride and pleasure in the work that I do as a family doctor, and my concern for the well being of my patients, I felt a kindred spirit in dealing with Mark, and am happy to write this note on his behalf.”

    Richard K. (Seller)

  • “Mark, you are a man of your word! Thank you so much for selling or house as you promised you would. You have made us very happy! Thank you again.”

    Gerry S. (Seller)

  • “Mark Baron is the ultimate real estate agent. He handled this sale with the greatest professionalism I have ever experienced in this industry. I would recommend him to anyone buying or selling properties.”

    Adrien A. (Cosmetics Mogul)

  • “Amazing job. Honest thorough diligence. Stayed on all of the details until the end. Would highly recommend him. He knows the market and great attention to detail.”

    Anthony S. (American Financier)

  • “Mark is one of the best brokers in the Hamptons. When you give him a listing, he really works hard and puts his heart and soul in it. He has amazing follow-up. He has incredible integrity, and I think the people in the Hamptons who know him and use him have complete faith in what he says, and what he does. I’d like to thank Mark Baron for really working hard and doing a great job in his role as a broker. This was a particularly tough one and the deal happened because of Mark. Thank you.”
