Diane Is the BEST!! She found me a house in East northport that was perfect for me. Diane worked day and night searching for a house for my friend. Once you have Diane as ur agent no need to look any further she is the Best of the Best. She follows up, always able to reach her. She is like family. Her and her daughter Stephanie are a fantastic team

I highly recommend Diane to anyone selling or buying a house. Diane is very professional & she is an expert in the business. She will give you her honest opinion and she makes sure her clients are always treated fairly. Her Negotiation skills and responsiveness are top notch. Diane goes above & beyond. She even helped me prepare my home, by moving furniture, so that it reflected the current buyer trend.
Thank you Diane. I will be calling you again in the near future.

I have known Diane personally for many years. So when It was time for me to sell my house, of course she was my first pick. (But I also looked at other realtors.). I picked Diane. WOW, I learned much more about her then! Diane is not just energetic and knowledgeable, she is completely committed to her task. Diane has built a team of professionals to support buyers and sellers alike. Stephanie, Lois and Helene are all terrific! At every step of preparing my house to sell Diane was there for me. She explained everything I needed to know...all the way up to my closing date. Her integrity and love for her work is outstanding. TEAM COSENTINO IS THE BEST
