    Connie by far is the best in town! I have bought & sold 3 homes with Connie and she has always got me the best price possible. But it’s her understanding of the large market with a small town girl touch. She really connects and goes above & beyond what a realtor does. She will get her hands dirty & truly helps from the bottom of her big heart! She has your best interests on both sides. She made it very easy & smooth transition to a new home.

    We had a amazing experience working with Connie and her team (Mugè and Katerina)! Connie is incredibly knowledgeable on the local market, and especially Wynstone. I can be (obnoxiously) picky, and Connie was determined to find the right fit. Having a team around her meant that someone was available to assist us at virtually any time. She ultimately got us into and helped us purchase a home before it hit the market, and we couldn't be more grateful. When it came time to sell our other home, Connie and team made the process extremely easy, ultimately selling the first weekend well over asking price. We couldn't have asked for more! We're so glad to have met Connie and will recommend her to all of our friends looking to move to the area!

    I had an outstanding experience working with Connie and her team. From the very beginning, they were knowledgeable, responsive, and incredibly professional. They took the time to understand exactly what I was looking for and guided me through every step of the process with patience and expertise. Highly recommend!

    I was fortunate to have the opportunity to work with Connie and her team. Connie is highly knowledgeable when it comes to the demands of the market and recognizing the story built around your home. She is able to bring buyers who appreciate the little things that will make your house a home for years to come. Connie and team are always available to answer questions, whether simple or unexpected. Her honest no nonsense approach enables the seller to relax and trust in the process.

    Connie Antoniou is a creative, well-respected, honest, trustworthy, successful, excellent, professional real estate agent. She not only represents herself well, but she also represents Jameson Sotheby’s well in her far-reaching marketing plans and executions. She goes over and above to meet your needs, meet contractors, do multiple showings—all with that great can-do attitude. Her years of experience and her wealth of knowledge are so valuable! Connie did an excellent job in selling our house. We have known Connie for many years, and we highly recommend her as a fabulous real estate agent whether you are buying or selling real estate!
