Led by Rosanne D'Agostino, Associate Real Estate Broker, The D'Agostino Team is recognized for delivering personalized service, strategic marketing, skilled negotiation, and an unwavering commitment to our clients throughout Long Island, including Suffolk County, Nassau County, and the East End.
Rosanne has built her reputation on honesty, professionalism, and lasting relationships.

Together, they combine extensive local market knowledge with innovative marketing strategies, responsive communication, and a collaborative approach that ensures every client benefits from the strengths and expertise of the entire team.

Testimonials
"Rosanne is an extremely professional and honest real estate agent. We are the first time buyer and have a lot of confusions during the entire home buyer process. Although Rosanne is the listing agent, she is very helpful and responsive to us. She does care for both seller and buyer's need. Rosanne patiently guided and advised us during the whole process, so we won't feel frustrated and hopeless especially under the COVID-19 crisis. We are thankful that we are finally able to close out the transaction and get our new home with her help. We would 100% recommend Rosanne to anyone who want to sell or buy a home."
-L Geng, Client
"We had been dancing around selling our home for years and reached out to Rosanne many times. She never hesitated once to answer our questions or concerns. We finally decided to list on March 26, 2023 and within three days our house sold over asking price. Rosanne made the whole process seamless from listing, open house and closing. We are grateful for her help, professionalism, and hard work. We recommend her 100% to anyone looking to buy or sell."
-Candice K, Client
"Rosanne helped us with the sale of our home. She is a true professional in every sense of the word. I could tell she loves what she does by the way she represented herself and the many ways in which she advertised our home. She was a pleasure to work with. She prepared us for the process and made us feel at ease. She kept us well informed during the process and made the process itself easy and accommodating to us. She is very responsive, punctual, and on top of everything. I could not be happier with the decision to hire her. As a result our house is under contract."
-MPlanas, Client
