Speaking & Appearances

Q: How did you get into real estate?

I’ve always been drawn to the intersection of design, lifestyle, and investment, and real estate was the natural place where those passions came together. Early in my career, I was originally licensed in Manhattan, where I found a mentor at Douglas Elliman who taught me one of the most valuable lessons of my career: capture a building. She told me to find a building I really loved, move into it (which I could never afford to do at the time), and then market and sell as many units as I could — and then move on to the next building and do it again. That advice opened my eyes to the power of focusing on one building at a time and building an entire business around it.

The truth is, I could never afford to live in one of those buildings myself. I didn’t come from money, and no one was going to help me get a place there. So I came to the conclusion that the only way I could ever truly “own a building” was to represent the developer, sell out every residence, and then continue reselling them for years to come. That became my path — moving from building to building, creating momentum and long-term value. To this day, it’s the most valuable lesson I’ve ever learned in real estate, and it’s why new development is where I’ve built my career.

Q: What was the first new development you worked on?

The Residences at Mandarin Oriental, Boca Raton. It was the first new development for Douglas Elliman in Palm Beach County — the beginning for everyone involved — and it became the foundation of my career.

My family has always had strong ties to West Palm Beach and Delray Beach, and one very stormy winter in Manhattan I got news that Douglas Elliman was opening an office in Boca Raton. I took it as a sign to leave New York behind and move permanently to Delray. Not long after, I read that the Mandarin Residences were coming to Boca Raton. Around that same time, I found myself at a private dinner hosted by designer Steven G. for the Auberge in Fort Lauderdale. The head of Douglas Elliman Florida was there. I summoned the courage to introduce myself, explained that I had been with Elliman in New York, that all I wanted was to be in new development, and that I wanted to work on Mandarin. The following week, I had an interview and was hired.

That project was a masterclass — not only in luxury and brand vision, but also in what not to do. I learned how critical timing is: you never want to launch prematurely, because buyers lose confidence quickly when they don’t see progress. I learned how to present a development with nothing — no marketing materials, no sales tools — and how to work as part of a team. Most of all, I learned the importance of creating your own opportunities. No one is going to miraculously hand you the life you envision; you have to step into the room, ask for what you want, and build it piece by piece.

Q: Where do you see your business in the next five years?

I see Dietz Elber Real Estate continuing to shape the luxury landscape in South Florida. My focus is on expanding our new development portfolio, building long-term partnerships with developers, and remaining the trusted authority for buyers and sellers in this space. In five years, I envision representing the most notable projects across Palm Beach County and beyond, while also mentoring the next generation of brokers in this niche.

I tend to live my life in five-year increments — it somehow helps me live each year to the fullest. At this stage, I truly have most everything I ever dreamed of: an incredible partner in both life and business, two of the most adorable and funny children, and the opportunity to build something of my own — not only for myself, but for my family and our legacy.

Every success I’ve had so far has stemmed from relationships — maintaining them, nurturing them, starting small and building over time. And at the core of it all is my genuine love for what I do. I am, quite honestly, obsessed with the details of new development. The process, the vision, the storytelling — it brings me so much joy. That passion is what will continue to drive me and my business forward over the next five years and beyond.

Q: What advice would you offer to someone looking to break into new development?

Be prepared to think bigger than just sales. New development isn’t about transactions — it’s about vision. You have to understand architecture, design, marketing, and buyer psychology. Developers aren’t just hiring someone to sell units; they’re looking for a partner who can help bring a project to life and see it through to success.

The first thing I’d say is: read — and when you read, train yourself to recognize opportunity. Then get creative about how to connect yourself to that opportunity. There isn’t just one path into new development. You might start out as an admin on one project and transition into sales on the next. Or you might begin as an assistant sales associate, working on salary alone (no commission) just to learn the ins and outs — then leverage that experience into a draw-and-commission role on your next development.

You have to be willing to make sacrifices. It’s not a punishment, it’s an entry fee. I once had a secretary on one of my projects who eventually went on to sell out a major branded residence. She made the right connections, learned as much as she could by simply being present in the sales gallery, and eventually earned her place as an associate. That’s how you make things happen — by being willing to start small, immerse yourself, and build upward step by step.

Q: What do you love most about new development?

What don’t I love? For me, new development is pure creativity. Every project is a blank canvas with the potential to redefine how people live, and I love being part of that process — from shaping floor plans and amenities to building a brand identity that truly resonates with buyers.

I get just as excited about the details as I do about the big vision. Crafting thoughtful floor plans, camouflaging doorways, adding heated drawers or hidden pantries, curating wellness amenities, pairing finishes to create harmony — it’s all part of the artistry. Watching those details come together to form beautiful, functional spaces that eventually sell out as a community is deeply rewarding. I love every step of it.
