"I can’t recommend Julie and her group enough. We have bought and sold 4 homes with her and each instance was completed with respect and professionalism. She is very knowledgeable about the market and has many contacts she works with to help you in every facet of the process. Her experience shows and her genuine friendly personality makes the stress of buying and selling a bit more enjoyable."

"Julie was our selling agent for the sale of our first home. Since it was the first time we sold a home, Julie's experience and knowledge about the market, the area, and the process was very valuable. She provided us with good guidance regarding timing for putting our house on the market and many tips for prepping it for sale. She maintained a professional demeanor while still providing us with insight. I would not hesitate to recommend Julie as an agent."

"Julie has been wonderful to work with, she was very attentive to our needs and requests and was quick to respond to us. When we needed to meet with her last minute she would find time to meet with us. She is very knowledgeable about the market and knows how valuable time is and did not hesitate encouraging us to quickly get our house ready and on the market. She wants the best for her clients and it shows in the effort she puts forth."

"Juli helped us sell our house when we were relocating to a different state. She was very professional and helped us feel at ease about the whole process. It was great that she was very knowledgable about market trends in our neighborhood and made us feel confident about the sale price she recommended setting. We got a good offer within a couple of days and completed the sale of our house without any delays before our relocation. We would recommend working with Julie for the experience she holds and her professionalism."

"Julie assisted us in our pandemic house hunt of 2021, where houses were going within 48 hours of listing at aggressive prices and little chance for communication with sellers. Julie made herself available for every quick turnaround showing and made sure we got any questions answered. She made sure that if a seller was going to cut an offer window short, we got in to see it. We ended up closing on a house recently. Ebay A++++++ would use again"
