I just closed on my first home in Danbury, and Svetlana made the entire process so smooth. I honestly thought buying a house would be a huge headache, but she’s very down-to-earth and really knows the Danbury area inside and out. She was always honest with me, never pushy, and always got back to me right away whenever I had a question. If you want a realtor who actually has your back and keeps things stress-free, Svetlana is the one. 10/10 recommend!

I couldn’t have asked for a better experience during the stress of selling my family’s home and transitioning to a new residence. Svetlana and Kelly were so professional and kind. Five stars! Dr. Smith

Svetlana and Kelley were absolutely fantastic throughout the process of selling my home, offering terrific insight and guidance from start to finish. They were both extremely kind, courteous, professional, and knowledgeable and did an excellent job at staging and managing the many showings. They were always available and great at communicating, keeping me informed, and quickly responding to any questions I had. They went above and beyond, and I would highly recommend them to anyone looking to sell their home. It was truly a pleasure working with them and a very positive experience.

Svetlana is amazing!! She guided us through the process and answered all of my many questions providing outstanding support and turn around time. Her knowledge and experience is evident as she provided a seamless process. Her patience and kindness was appreciated, as she helped to reduce the worries that a first time home buyer goes through. I highly recommend Svetlana and would have her represent us again in a heartbeat. Kudos Svetlana, you are a rockstar!!
