Christie is the best real estate agent I know. I have used her for several transactions and she has been amazing on all of them. Her market knowledge, problem solving skills, and professionalism is fantastic. She provides the feedback and expertise that can only be provided by someone that absolutely loves their job and their clients.

Christie is amazing! We were referred to her by a friend and we have zero regrets taking that recommendation. She was always professional and communicated with us every step of the way. It made the entire process so easy and she removed so much stress. She even showed up to check the a/c when we couldnt get to the house. Even after the sale, she continues to help us and thats so important for a family not from the area who is unsure who to call. We highly recommend her!

Christie was great to work with! She has vast knowledge of the real estate market and gave us invaluable advice. We had to work with Christie remotely and she was very helpful resolving issues with the house and coordinating the work. Best of all, she sold the house in December when we were told houses don't sell well that month.

Working with Dana was an amazing experience. She was very knowledgeable about the areas we were looking buy. She showed up multiple options within our price range. She went over and beyond the buying experience to ensure we were well informed at each step of the process all they way through closing and after. 10 out of 10 would recommend her for anyone looking to buy a home in the STL area.

Lisa was amazing though the whole process; finding a new house helping us connected to financial people to helping us sell the old house. It was long and stressful and she was very supportive and understanding. 5 out of 5 stars would recommend.
