Meet Jeanne Leonard

Jeanne Posillico Leonard

I have been fortunate to live in the Cold Spring Harbor and Huntington area for many years. The North Shore offers an amazing lifestyle, we have beaches, great restaurants, thriving towns and villages, and entertainment. I love living here, and have a deep appreciation of what this beautiful area has to offer. My family has been on Long Island my entire life, and I have raised five children here. I am delighted to help others experience everything our unique community has to offer.

In my past business experience I was partners in a local business, and additionally helped create a real estate development company. This business experience helped me put my knowledge and experience together to build a comprehensive approach to selling real estate. As a real estate professional my number one priority is to assist my clients whether they are buying or selling a home. I pride myself staying up to date with all of the current trends of our market and use all the resources available to create a winning combination for successful transactions.

The success I have had in the real estate business is primarily due to the care and attention I give each and every client. I approach each transaction as an opportunity to forge long lasting relationships, both personally and professionally.
