Our Team

Columbia Vitolo Team

We have sold over $1 billion in real estate and have over 28 years experience.

Great things are achieved by a series of small things.

A team always outperforms an individual. With over 35 years of experience selling luxury real estate in New York City, what drives us most is making the experience of buying and selling real estate both a pleasurable and profitable one for our clients. As a team, we strive every day to elevate the level of service that we give to our clients. No matter who the client is or what their budget, our goal is to provide an exceptional and consistent experience from start to finish.

The result is that we exceed most people’s expectations of a real estate professional. Whether you are a buyer or a seller we have learned it is never just a house, an apartment or a zip code. It’s more than hardwood floors and pre-war details. It’s where you come to life, are inspired, and raise your family, or it is one of your biggest investments. It’s the first and best expression of who you are as an individual, a couple, or a family.

We never forget what a home represents to our clients personally and financially and it is with this responsibility that we act every step of the way. We have found the only way to achieve these high standards is to only hire people who truly enjoy what they do and want to share their knowledge with you. Get to know us below.

Dayanne has helped me from time to time with apartment searches and I have never met a more diligent and enthusiastic agent. She is thorough and honest in her dealings and gets you what you want. I highly recommend her and will never work with another agent unless I leave NYC.



Dayanne is everything you can possibly ask for in a real estate agent, she loves what she does, she is kind, honest and devoted to doing her best. I am honestly very impressed by how she handled my situation and helped me have better results than I thought I could.



Dayanne couldn't have been been more professional and caring. She found our dream place, negotiated a great price for me and my wife, gave us all of the attention we needed as first time buyers and made us feel super secure. I feel lucky that we met and worked with her. Will definitely be recommending her to anyone I can.



“Dayanne has great energy and loves what she does. Which we found important when searching for a home in NYC. She was able to find us exclusive apartments that were fresh to the market and met our requirements. Dayanne was also very human about the process, never too anxious about closing a deal and was very transparent.”



Dayanne was far better than any other broker I have ever worked with. She was quick, responsive and extremely honest. Treated me like a friend and helped me through the whole process much quicker than I thought it was possible. She also got me a much better deal than I would have on my own. In a big city like NYC is very rare to find brokers that actually care. Couldn't be happier, I love my home!



Dayanne was spectacular from the first time we got in contact. Professional, courteous, kind, fair and knows a lot about the downtown area and the market. I can't say enough good things. This is the agent you want to help you find your dream home!
