"Trustworthiness. It's one of the most important characteristics that a buyer or renter looks for in his broker. When my wife and I were looking to purchase an apartment last year, we knew that the process would be a daunting one. We also knew that we needed to have someone on our side whom we truly believed had our best interests at heart. Daniel was that broker."

Peter, Manhattan

"Sumner is a rare gem of honesty and integrity in the New York City real estate world. He will work hard to make sure you get a good deal which is a lot more than one can say for most of the other agents out there."

Joyce and David,

"Brett has changed our perception of NYC brokers for the better (much better). He is genuinely attentive to our apartment needs and never wasted our time."

Emma, Manhattan

"Sumner is great at what he does and I would definitely recommend him. If you want quick and painless results when shopping for real-estate choose Sumner Crosby."

Sharyn, Brookyn

"To say that I highly recommend Daniel Chun is truly an understatement. His expertise in everything real estate related, coupled with his ability, determination, and passion for matching people to places, makes him the only real estate agent I will ever use again."

Jeff, Manhattan

"I highly recommend Sumner to anyone looking to avoid the stress of the new home hunt in New York City - you will be in excellent hands!"

KJ and Hannah, Manhattan

"Purchasing a home in New York can be a daunting process and finding a trustworthy broker even more so. Thankfully we were introduced to Dan, who from the minute we met, put our minds at ease. We are so thankful to have met Dan and cannot recommend him more highly to anyone who is in the market to find a new home."

Jacob, Manhattan

"If I had a few keywords to describe Daniel, all of which comprise a recipe for success in an uber-competitive and unpredictable real estate deal market like Manhattan, they would be “analytical, thoughtful, methodical, poised, persistent, organized, problem-solver, detail-oriented.” I could not be happier with my experience with Daniel. I would recommend him to anyone without hesitation."

Jennifer, Manhattan

"I would absolutely recommend Brett to anyone looking for their next home/business space and will continue to use him personally for any of my real estate needs. He definitely lives up to his Rock Star name."

Doreen, Manhattan

"Thanks to Sumner I found my ideal apartment. He was diligent, a great listener and very responsive."

Tim and Priscilla, Manhattan

"Dan and Jon on the Formation Team are amazing to work with and we highly recommend their services to anyone purchasing a home in NYC. They guided us as first time home buyers in a very competitive Manhattan market with their wide knowledge base, their data-driven, analytic approach and their extreme thoroughness to detail."
