Lori was our agent throughout our home purchasing journey. She was absolutely fantastic. She provided sound/real advice and support, which are critical elements in a challenging Long Island market. Most importantly, she helped us manage our own expectations based on her knowledge of the market and the areas we were looking in. This helped us keep our offers competitive and prevented us from becoming emotional buyers. Lori's communication skills are exceptional. Communication is another critical element and as a buyer in a challenging market, you need an agent that is able to articulate your position in a timely fashion. Thanks to Lori, we always knew where we stood on a house that we placed an offer on. Additionally, we were able to close on our dream home within 4 months of working with Lori! Highly recommend Lori based on our experience!

Margaret was extremely knowledgeable, had excellent communication skills, was very understanding & emphatic, and got the job done quickly exceeding expectations!
My experience working with Lori Sheehan when selling my home was excellent. From the very beginning, Lori was so knowledgeable, helpful, and kind, and she made what can be a stressful process so much easier! She was always available when we needed to communicate with her, helped us understand every step of the process of selling a home, and her advice and guidance resulted in us getting competitive offers after the very first open house. I would enthusiastically recommend Lori to anyone who is looking to sell their home, as she is a delight to work with!

Joe was incredibly knowledgeable and helpful throughout the entire process. He was available anytime I needed or had a question. Very nice guy and would work with him again. I recommend him over and over.
from day one to the final day of sale, Lori was there for us. every showing, every question, every offer. her professionalism and knowledge, her personality, a class act all around! thank you Lori for everything!
As a real estate agent myself, I had the pleasure of working with Lori on my own personal purchase—and I can confidently say the experience was exceptional from start to finish. Even coming from within the industry, I truly appreciated how smooth and seamless she made the entire transaction. Lori was professional, responsive, and incredibly detail-oriented, ensuring that every step of the process was handled with care and efficiency. It’s not always easy to find another agent you fully trust with your own deal, but Lori exceeded my expectations. I would absolutely welcome the opportunity to work with her again and highly recommend her to anyone looking for a knowledgeable and reliable real estate professional.
Lori Sheehan recently helped us sell our property. From the moment we met her she put our minds at ease about the sale. Once we settled on an asking price, she expertly reached a large number of potential buyers and personally showed the property. In an amazingly short time, Lori found us the perfect buyer and the perfect price, which was way above our asking price!
Lori was amazing and helpful!
