- I cannot express how amazing Shaughnessy was when we were buying our first home! Shes constantly finding and sending us homes to see, always answers her phone anytime I needed her, would come with us to everyone showing knowing exactly what to look for in a good home, and what to avoid in a bad home. She’d fight and haggle for us, and neverrrr left us waiting for answers. We used everyone too she recommended—from inspector to lawyer! I cannot express how amazing this fabulous woman is!!!!Sydney and Ryan F.
- Shaughnessy was extremely attentive and went above and beyond so many times while we were selling our house. She was a pleasure to work with throughout the entire process. She was always quick to respond, would offer her opinion, but was never pushy. From the start she took her time to meet with us and actually listened to our needs and wants. She really was a pleasure to work with, and we would recommend her to anyone in the area.Jennifer Wilking
- Even if I could give 100 stars, that still would not be enough. Shaughnessy, transformed our home buying experience. She turned our dreadful & upsetting experience into an easy enjoyable process. Not only is she beyond professional and knowledgeable she is a kind, patient & a really genuine person. I felt supported and guided by her years of experience. You can truly rely on her to help you find a perfect fit for your family not just an house and then to close the deal in a smooth process that doesn’t leave you feeling overwhelmed. I will only entrust her with my future home buying needs & feel confident recommending her to my family and friends. She is a true gem.Katie and Justin L.
- Shaughnessy was amazing from selling our home last year to buying our new one this year. From contract to closing her team was amazing.Margaret and Bill F
- I’m a Realtor myself, and when it came time to relocate a relative to be closer to my family, Shaughnessy came highly recommended by another colleague of mine - and it’s easy to see why. She was fantastic in helping my family navigate every aspect of the process - preparing the home for sale, arranging vendors for various tasks, coordinating the entire closing process, and she made the business and practical aspects easy. It’s challenging to coordinate everything involved in a cross-country move from a distance, and Shaughnessy was invaluable - I will happily recommend her in the future. Thank you for all you did for our family!!Kelly Keates
- Working with Shaughnessy was a complete joy!! Not only did she sell our first house (starter home) for us and help us find our forever home but she held my hand through the whole process. She has so much knowledge and was always readily available anytime. She even helped me pack up my house! She is like a superhero. I was anxious at times and she was always there to put me at ease. I had a ton of questions and was nervous about selling and buying. She knows the market so well she was right on the money when she said what my house would sell for and sold it in one weekend!! Shaughnessy was ready to go all over Suffolk County to help us find our forever home and we did. Also in one weekend!! I couldn’t have done it without her. She was prompt, knowledgeable, professional and so much fun to be around. Having Shaughnessy as my real estate agent was the easiest decision I made in the process and I wouldn’t have it any other way!! Thank you Shaughnessy for all your hard work and dedication!!Jeanette and Jason D.
- Shaughnessy is an amazing realtor, and wonderful to work with. We purchased our first home with her, and a few years later, had an unexpected out of state transfer with work. Within days, she had us listed, photographed(beautifully), and held two open houses. Within a week of listing, we had an accepted offer that was over asking. She is knowledgeable, truly understands the Long Island market, and can guide you through the every step of the process. I've recommended her to anyone I know that is buying or selling.Michelle H.
- Shaughnessy was absolutely amazing. She sold our home in record time and was able to find our dream home in the neighborhood that we wanted. The whole process was as painless as it could be and I couldn’t be happier with the outcome. I’ve recommended Shaughnessy to close friends and they’ve all had the same result. Whether you are looking to buy or sell (or both!) she’s your gal!Stephanie and Kieran C.
- Where do we start with the unbelievable experience we had selling our West Islip home. Shaughnessy and her team from the very beginning of the listing, marketed, showed and sold our home in these difficult times for more then we could have dreamed of. Shaughnessy’s professionalism and experience during the entire time was exceptional. She is a true client advocate that makes a stressful situation a smooth process from beginning to end. She really is second to none. So if your looking for a realtor call Shaughnessy you will be happy that you did.Ken and Maria S.
