"If you are looking for the absolute best real estate team in NYC, look no further than Michael Franco, Greg Holzmann, Naomi, and their outstanding team! They guided me seamlessly through selling my condo and buying a co-op—which is notoriously challenging for first-time buyers. From day one, they understood exactly what I needed and made the entire process smooth and speedy. Greg was especially incredible, coordinating every apartment viewing with precision, sending timely reminders for each appointment, and ensuring our schedule was logical and stress-free. His attention to detail truly took the anxiety out of the whole process."

He is highly qualified having previously worked in investment banking. Very experienced in negotiation and good with the numbers. Extremely thorough and competent. Yes Greg is the real estate agent that goes the extra mile and is available almost 24/7. Great follow up and attention to detail. I have referred Greg to friends and my partner is selling his apartment through Greg. Will definitely work with him again." - Kate

"I recently used Greg as a realtor helping me find an apartment in New York City. As I was unfamiliar and somewhat overwhelmed with the ins and outs of NYC real estate market, Greg was great to work with and made the process run smoothly and less daunting. Within a very short window, Greg was able to pull listings together that fell within my price range, set up appointments to view listings and patiently addressed all of my questions and concerns. I am so grateful to have someone like Greg be able to take control and coordinate everything and take the burden and pressure off of me as I relocated." - Catie

"My wife and I were recently displaced from our apartment and needed to find a new home ASAP. Greg was extremely sensitive to our needs and tight timeframe. He worked tirelessly to find listings, diligence the properties and show us as many options as possible until we found a home we loved. Greg is knowledgeable and hard-working, but above all, he CARED about finding us a new home when we really needed one. I would recommend Greg to and friend or family member who is looking to buy or sell a property and will be working with him again in the future!" - Corio
★★★★★
"Greg is a thoughtful, communicative professional who takes a lot of time to understand your needs and concerns. The transition to a new city or new home can be scary or overwhelming, but Greg's manner and knowledge can make the process a lot easier. Even though I did not apply one of Greg's listings, it was a pleasure working with and getting to know him throughout this process, and I know that I would have similarly positive things to say had Greg and I gone through the application and lease-signing process together." - Dylan
