Testimonials

Peter W.

I am deeply grateful to Kate Wollman-Mahan and Maria Kourepenos, whom I met through the Princeton Alumni network. They are so extraordinary that everything I’ve written about them until now sits on the page like an uninspired junior paper written by a star athlete hoping to get through life on sports and good looks. Working with them was one of the best decisions I’ve made in years. Despite my living across the country, they successfully sold my family’s Upper East Side co-op—an estate property requiring a full renovation—in a challenging market. From the outset, Kate and Maria demonstrated exceptional market knowledge, strategic insight, and steady judgment. They navigated a complex transaction - despite a challenging buyer and complicated financing - with professionalism, foresight, and meticulous attention to detail. We went through multiple strange twists and turns and went to the c…

They navigated a complex transaction - despite a challenging buyer and complicated financing - with professionalism, foresight, and meticulous attention to detail. We went through multiple strange twists and turns and went to the closing where even the buyers’ attorney was not sure if the buyers would show up and sign. They were savvy negotiators, showing discernment in choosing their battles and skill in navigating different personalities to ultimately get across the finish line. Smart, ethical, and highly responsive, Kate and Maria were a true pleasure to work with in every respect. I recommend them without hesitation to anyone buying or selling in New York City.

Working with Kate and Maria was like having two seasoned brokers, project managers, and strategists all in one. From the start, it was clear they were creative problem solvers who brought far more to the table than simply listing an apartment. They coordinated nearly every aspect of preparing the home for showings—working with contractors, finding an HVAC company willing to take on a single job in the middle of summer (no small feat), bringing in a renowned architectural landscaper, and even helping shepherd an open permit to its close. Their deep network of trusted vendors made the entire process far easier and more efficient than I could have imagined. Maria and Kate helped transform the garden into a true New York City oasis and even created a beautiful time-lapse video capturing the space from dawn through dusk. They also worked closely with the stager to achieve exactly the look…

They also worked closely with the stager to achieve exactly the look I envisioned—so successfully that the buyer purchased a substantial amount of the furniture. Most impressive of all, the apartment ultimately sold for over 15% more than I had originally paid for it, which is particularly notable in a market where many New York City home prices have remained relatively flat. Plus, we listed and closed in just six months. They did far more than I ever expected from a broker, and they were a pleasure to work with throughout the process.
