Rosanne sold our house in Coram. She was very professional, the promotion of the property was done in a highly professional manner. This lead to over 100 people coming to the open house ending up with numerous offers. In the end we ended up selling the home for higher than the listed price. I would not hesitate to recommend her again.
-JPerrone, Client
A real estate agent who became a true friend along the way during the selling of our home. A true professional who worked tirelessly for 3 months during the closing on our home. I can't believe there is a more sincere dedicated agent that Rosanne. I can't thank her enough and now I am so proud to call her a good friend.
