John Frangeskos was a Godsend to me and my family. He worked diligently to learn every detail of my home, and was able to translate that knowledge to all prospective home buyers. I was extremely happy to accept the more than generous offer that his client brought to the table. I closed last month, and couldn't be happier with the deal that John put together. Thank you John Frangeskos!

We worked with John for the sale of our home and couldn't be more pleased. He is professional, courteous and extremely detail oriented. He continuously kept us up to date as the sale progressed. He was generous with his time taking on more than his share of the tasks necessary to get the sale closed. We recommend him with the highest regard and without hesitation.

John, thank you so much for your excellent work in selling our house! Your professionalism and dedication made the entire process smooth and stress-free. We were particularly impressed with your attention to detail and your ability to find the right buyers so quickly. We couldn't have asked for a better experience.

Anastasia

We cannot speak highly enough of John and the incredible job he did selling our family's hotel in the Hamptons. From start to finish, he was the epitome of professionalism, discretion, and drive. This wasn't just a property-it was part of our family's legacy, and John treated it with the care and respect it deserved. His knowledge of the market was unmatched, and he brought in serious, qualified buyers almost immediately. Throughout the entire process, he kept us informed, advocated for our interests, and handled every detail with precision and grace. What could have been a stressful and emotional experience turned into a seamless transition, all thanks to his expertise. John didn't just sell a hotel— he helped us close a chapter with confidence and pride. We are so grateful for his dedication, integrity, and results-driven approach. If you're looking for someone to go above and beyond, John is the agent you want in your corner.

John was great to work with - he helped us close on our Sag Harbor dream home. Very communicative, responsive, and flexible. Really appreciated John's positive attitude and some of the introductions he made to move the deal along, happily recommend him for the Hampton's market!

Ben S.

We worked with John and the Corcoran team to purchase a property in Southampton. Throughout the process, John was professional, patient, detail oriented, and responsive. He clearly understood our needs, the Hamptons market, and identified relevant opportunities at the right times. We were also impressed with his integrity and honesty. When it came time to make offers, he and James Peyton were experts at helping us negotiate and close. They are the best real estate team we have ever worked with. We would strongly recommend them and look forward to working with them in the future!
