Nancy was excellent to work with and very patient.  My wife and I saw dozens of houses with her, never felt pressured, and we found the one that was right for our family.  She is professional and personable - a refreshing combination.  Robert & Melissa Dooley


We are so thankful to have chosen you as our realtor. You have given us hope in 
finding our first home since day one. Without you ,as friendly and aggressive as 
you are, we wouldn't be where we are and that's in our dream home! 
Thank you from the bottom of our hearts for all the hard work you have done for 
Amy and Michael Carretto Jr.


When we first met Nancy, we knew what we wanted our dream home to be - we just didn't know where it would be. Since I was born and raised in Nassau County, my ideas were pretty set on buying a house and living there. When the time came to start showing us houses, she made sure to get all of the areas we wanted in Nassau, but she also added some of her own ideas for places we didn't think of in Suffolk. Much to our surprise, the houses she showed us were a much better fit for us than the ones we originally liked. She offered us valuable information whenever we needed it, but she was never overbearing and always let us form our own opinions on each home. When she found us our dream home, she could see how excited we got for it. Before we even put an offer in, she had already done her homework in the area to present the most reasonable offer without costing us anymore than it had to. After our offer was accepted, she walked us through the entire home-buying process - there with us every step of the way. No question was too little and no time was too late. She made a very intimidating process seem like it was a breeze. We can honestly say if it weren't for Nancy we wouldn't have even ended up in the same county as our dream house.   Sincerely, Joe and Andrezza
