Diana is a NY & NJ Licensed Real Estate Salesperson

With over 20 years of hands-on experience as a landlord and property manager, I bring a deep, practical understanding of real estate to every client I serve.

My passion for the industry began long before my career did, and five years ago I transformed that lifelong interest into a full-time profession. Since then, I’ve built my business on expertise, integrity, and a genuine commitment to helping others achieve their goals.

I take pride in guiding clients through some of the most meaningful financial decisions of their lives. Whether I’m helping first-time homebuyers navigate the journey to homeownership or supporting investors as they expand their portfolios, I offer personalized service, clear communication, and a wealth of real-world knowledge. My goal is always to provide confidence, clarity, and a smooth experience from start to finish.

Driven, dedicated, and deeply invested in my clients’ success, I look forward to helping you reach your real estate goals—no matter where you are in your journey.

1/16/2022 - Liza W- Helped me rent a Single Family home in Meiers corners, Staten island, NY.

I can’t say enough about Diana. She has been a guiding light in a very crazy and rollercoaster process. Not only did she make time for me when others ghosted, but she dealt with my anxiety and helped me handle the stress that comes with moving. She was able to find me houses, work with other brokers, validate NYS law when necessary, and find me the perfect home from start to finish. I couldn’t recommend a better person for the job. Thank you so much, Diana! You have given our family the gift of an easy, seamless process so that we can enjoy our new happy home.

Bought a home in 2023.
I've now worked with Diana twice: she helped find me a rental AND negotiated extras and finally, she walked me through every step of purchasing my forever home. Diana is not pushy like many agents I've dealt with in the past. She is gentle in nature toward her clients while being assertive in negotiations to get what is needed and wanted. If I didn't have Diana through this process, I'm not entirely sure I would have finished. Buying a house is not easy, but Diana will make you feel like it is.
