About The D'Agostino Team at Douglas Elliman Real Estate

At The D'Agostino Team at Douglas Elliman Real Estate, we believe every client deserves exceptional representation, expert guidance, and a real estate experience built on trust. Whether you're buying your first home, selling a luxury property, relocating, downsizing, or expanding your investment portfolio, our mission is simple: to help you achieve your real estate goals with confidence.

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. She understands that buying or selling a home is more than a transaction—it's one of life's most significant milestones. Every client receives the same level of dedication, whether purchasing a starter home, marketing a waterfront estate, or selling a cherished family property.

Working alongside Rosanne are Pam Ramirez and Yesenia Hamze, experienced real estate professionals who share the team's client-first philosophy. 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.

Local Knowledge. Global Reach.

As part of Douglas Elliman Real Estate, one of the nation's most respected real estate firms, The D'Agostino Team offers clients the perfect combination of local expertise and global marketing power. From professional photography and digital advertising to social media campaigns and targeted marketing, we leverage the latest technology and Douglas Elliman's extensive network to maximize exposure for every listing while helping buyers discover the right opportunities.

Our deep understanding of Long Island's diverse communities—including Port Jefferson, Stony Brook, Smithtown, Lake Grove, Centereach, Ronkonkoma, Patchogue, Westhampton Beach, and surrounding neighborhoods—allows us to provide valuable insight into market trends, pricing strategies, schools, lifestyle amenities, and local resources.

Our Commitment

We know that no two clients—and no two transactions—are alike. That's why we take the time to listen, understand your priorities, and create a customized plan that aligns with your goals.

When you work with The D'Agostino Team, you can expect:

  • Personalized guidance from consultation through closing
    Honest advice and transparent communication
    Strategic pricing and innovative marketing for sellers
    Skilled negotiation focused on protecting your interests
    Local market expertise backed by Douglas Elliman's global resources
    Responsive, attentive service every step of the way


More Than Real Estate

For us, success isn't measured simply by closed transactions—it's measured by the relationships we build and the trust our clients place in us. Many of our clients become lifelong friends, returning to us for future moves and confidently referring their family and friends.

Whether you're buying your dream home, selling your current property, or simply exploring your options, The D'Agostino Team at Douglas Elliman Real Estate is ready to guide you with integrity, expertise, and a commitment to exceeding your expectations.

Your goals become our mission—and your success is our greatest achievement.

"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."

  -Eunice M., Client

"...We got sound advice for upgrades and when we had trouble securing people/folks not showing up for jobs she not only helped us get reliable people but also never pushed us to list quicker than we were ready. We absolutely love our house and she knows it..."

  -S Denise, Client
