Jerry Hallissy has been a Port Washington resident for 20 years. He has worked on some of New York’s most complex architectural and construction projects throughout his career. He brings over 40 years of industry experience to the Hallissy Group, which lists and sells properties in the New York metropolitan area. Unlike other realty services in the Port Washington/Manhasset/Sands Point Long Island area, where the office is located, the Hallissy Group is active throughout the New York metropolitan area including Manhattan. So if you are thinking of selling on Long Island and moving into that Manhattan pied-á-terre you have always dreamed of, the Hallissy Group can be your ultra service concierge on both ends of the deal. On the other hand, if you are thinking of leaving the Big Apple for a suburban home or condo, the Hallissy Group can be your ultra service concierge on both ends of the deal as well.

Jerry believes that the role of a Real Estate Broker is to guide his agents through the career building process, taking the time and providing the input to help them identify and achieve their personal goals. Jerry is committed to excellence in service and the values and visions of the company, as well as to the highest ethical and professional standards. He establishes trust and mutual respect among all participants on his team. His approach is honest and straightforward.

Aside from his top real estate industry management skills and excellent reputation as a facilitator of your goals, he is a trainer at the Hallissy Group. Jerry loves mentoring new, open minds and coaching people to reach their full potential. He continues to serve his real estate industry clients and delivers the same top-notch service and expertise for which he has always been known.

Hallissy Group maintains the latest technology systems and social networking groups with customers and other agents. Hallissy Group markets its sellers’ listings through writing advertising and newsletters, holding open houses, using social media and internet platforms. Hallissy Group can assist its clients through its extensive knowledge of builders, bankers, architects, attorneys, mortgage brokers, and accountants. Earning the client’s trust and building client rapport enables the Hallissy Group to continually develop referrals through satisfied clients.
