About Dennis

Dennis Saglam

Integrity. Expertise. Discretion. Results.

In the world of high-stakes real estate, where every detail matters and discretion is key, Dennis Saglam has built a reputation as a trusted advisor for discerning buyers and sellers across Long Island and the Hamptons. With nearly a decade of hands-on experience navigating luxury transactions in the Hamptons & Long Island, Dennis delivers more than just deals—he delivers peace of mind.

A White-Glove Experience from Start to Finish

Whether it’s preparing a property for the market, negotiating a complex off-market deal, or aligning with the right legal and financial professionals, Dennis offers full-spectrum expertise from soup to nuts. His clients—ranging from seasoned investors to legacy-minded families—consistently turn to him for his calm, no-nonsense approach and ability to get things done.

What Clients Value Most

Dennis leads with honesty, direct communication, and a relentless commitment to client success. His business is built on three core pillars:
• Integrity — Always doing what’s right, even when no one is watching.
• Transparency — Clear guidance with no fluff, no pressure, and no surprises.
• Execution — From pricing to marketing to negotiations, Dennis brings clarity and control to every step of the process.

Technology Meets Tradition

As the co-founder of ListingCopy.ai, Dennis merges cutting-edge AI with timeless real estate fundamentals. His forward-thinking strategies are matched by a deep respect for the personal nature of each transaction—especially in the luxury space, where privacy, timing, and positioning are everything.

A Modern Agent With an Edge

At a time when the market is evolving faster than ever, Dennis brings the rare advantage of next-generation thinking paired with real-world experience. As a younger agent who has already closed major deals and launched a real estate tech company, he’s proof that innovation and track record can coexist.

More Than Just Real Estate

Outside the dealmaking and data, Dennis is a lifelong water enthusiast who grew up boating on Long Island’s South Shore. He’s a committed student of personal growth, a lover of good design, and someone who believes success should be both built and enjoyed. That mindset—focused, intentional, and well-rounded—guides how he shows up for every client.

Dennis Saglam: When It Has to Be Done Right

Choosing Dennis means partnering with a seasoned professional who treats your property and goals with the same care and intensity as his own. If you’re looking for a sharp, grounded, and strategic agent who values your time, protects your interests, and delivers results—you’ve found your guy.

If something needed to be addressed, he accomplished it promptly. He negotiated a good sales price for my home and was successful. I would highly recommend Dennis to anyone buying or selling a home.

When we first decided to sell our house, we were not going to hire a real estate agent—as we realized how difficult this could be. We decided to use someone a friend recommended, Dennis and Sandra Saglam of Douglas Elliman Real Estate. Best decision we could have made. They took all the headache away from us (well as much as possible anyway). Dennis became the reassuring voice that I needed to hear. Always calm and coming up with solutions. He always picked up my calls immediately or would call me back within minutes of leaving a message. I would absolutely highly recommend this team—they certainly earned their commission and then some.
