    Katherine was a pleasure to work with. She always keep me informed on when she was showing the home as well as helping me understanding the different offers. She was able to get a buyer in a short time and was there with me every step of the way.

    Katherine is the ultimate professional where real estate is concerned. She was in constant communication with me, set up and attended open houses providing potential buyers with information about the house and area. Her team that handled photos , flyers and social media posts did an amazing job. With Katherine at the helm the house was sold in 4 weeks!

    Katherine was incredible from start to finish. She went out of her way, above and beyond, to help my sister, who has some special needs, get herself organized and packed up for the move. She worked to get the highest price for the co-op, recommended a wonderful attorney for the closing and is just an outstanding, lovely individual. I would recommend her over and over again.

    Katherine was a pleasure to work with. She is honest, friendly, very accessible & extremely knowledgeable. She sold a house for me that needed a lot of work & she managed to make the sale happen. I also had a billion questions for her & she ALWAYS responded right back with patience & understanding. Anyone would be lucky to have her as their agent!!

    Katherine did an excellent job in the sale of our home. Her marketing was top notch. From the photos, to the drone pictures, to the virtual tour of our house, it attracted so many buyer to our open houses - we had a line out the door! In a period of only 3 days and only 2 open houses, we received over 10 offers and multiple offers were over asking. Katherine helped to negotiate the best offer for us, which ended up being significantly over asking. Throughout the whole process, she was very easy to work with, very knowledgeable and professional, and always available for questions. She made what could have been a very stressful process much, much easier for us. I highly recommend her.
