As a long time resident and business owner, I have had the privilege of living and working in the Cold Spring Harbor and Huntington area for many years. This allows me the opportunity to provide my real estate clients with an in-depth understanding of the local market. I have built and maintained local businesses, including a real estate investment company. I love this area and I am fortunate to have raised five children here. I have a deep appreciation of what this beautiful area offers. I am delighted to help others experience the same level of appreciation for this unique community.

As a real estate professional, my number one priority is assisting my clients to find their perfect home. I put my knowledge and skills to work, having developed a well-crafted marketing plan which delivers the most comprehensive exposure for home listings in today’s competitive real estate market. I pride myself in keeping up-to-date with all of the current trends, and use all aspects of Daniel Gale Sotheby’s International Realty’s exceptional resources. It’s a winning combination.

The success I have in this business is due to the care and attention to detail I give each and every client when they are buying or selling. I approach each transaction as an opportunity to forge long-lasting relationships, both personally and professionally.
