About Caroline
Real estate is about more than buying and selling a property—it's about understanding each client's goals and creating a thoughtful strategy to help them achieve them. My career has given me a unique perspective on every stage of the real estate process. Before becoming a licensed real estate salesperson, I built my experience in luxury home staging, marketing, and operations, developing a deep appreciation for how presentation, preparation, and attention to detail can influence a property's success. Today, I bring that same strategic approach to every client I represent.

As a Real Estate Salesperson with Compass, I work with buyers and sellers throughout New York City, guiding them through each step of the process with clear communication, market knowledge, and a personalized approach. Whether preparing a home for market, developing a marketing strategy, negotiating on behalf of a client, or helping buyers navigate a competitive market, my goal is to make every transaction as seamless and successful as possible.

Known for being highly organized, responsive, and detail-oriented, I believe exceptional service comes from anticipating clients' needs, communicating proactively, and never overlooking the small details that make a meaningful difference.

I am passionate about helping my clients make informed decisions with confidence and look forward to building lasting relationships long after the transaction is complete.


Client Testimonials

★★★★★ 5 Star Review
" Caroline was so wonderful to work with. Attentive, responsive, patient and understanding to all my concerns and needs. A breath of fresh air after weeks of apartment hunting.. " - Kayla, Condo Renter

★★★★★ 5 Star Review
"Caroline is a pleasure to work with. She listened to our needs and found plenty of listings to view, many that we would not have thought of to view ourselves. She communicated proactively with the sellers' agents and did everything else so that we could focus just on finding the place we wanted. I can say, we would not have been able to complete the co-op application process without her!" - Shashi and Paul, Coop Buyer

★★★★★ 5 Star Review
" Caroline was very helpful, was very responsive, and was very easy to communicate with. I worked with her both on renting my condo and also when I looked to buy another condo, which I ended up not buying. " - Tamar, Condo Seller/Buyer/Landlord

★★★★★ 5 Star Review
" So happy with my new home in Brooklyn Heights! I began my apartment search with a list of what I thought I wanted, and Caroline helped me refine that list into clear wants, needs, and must-haves that gave real focus to the process. Her attention to the details that mattered most to me made the search both efficient and productive. She consistently guided me toward apartments that were strong matches, and before long, I found one I truly love. It had been years since I had gone through a New York co-op purchase, and I wasn’t fully comfortable with everything the process would require. Caroline’s knowledge of the co-op buying process—especially navigating the application requirements—was invaluable. She made what initially felt complex seem manageable, which eased any anxiety I had. Her skill during the offer and negotiation process was exceptional and ultimately resulted in a smooth, stress-free purchase. I’m so happy I chose Caroline—and Compass—for my apartment search!" - Mary Willoughby, Coop Buyer
