She holds her team accountable and equally as charged to get it done. Our purchase took us less than 30 days from start to closing. We are still blown away and can't wait to begin our bigger project that Connie has agreed to support and partner with us since we have many big things to do and Connie knows everyone! Reviews are easy when you mean every word, and if you had or have any doubts about who you're dealing know one things, Connie's the very best!

We relocated to the Chicago area September 2019 after 35 years in Kansas City. It was difficult to even know where to begin that house hunt until a former neighbor suggested we give Connie a call. That was the best thing we did because she truly understood all the expectations we wanted in our new home. She actually found the perfect home and location for us the first day we met! Fast forward one year later and we were being transferred back to Kansas City and needed to sell our awesome home quickly. We called Connie and she again worked her magic and got it on the market for us in record time. Within 30 days we had a contract on our house, which made our return to Kansas City much less stressful. Connie and her team once again went above and beyond our expectations. She was always available and made sure the entire process and our move to Kansas City went smoothly. The time she devoted to selling our home made us feel we were her #1 priority. Connie Antoniou is an amazing, professional, caring person and realtor that we highly recommend!

She recently helped me sell a land parcel which was listed for awhile and proving difficult to sell. Not only was she dedicated to getting this parcel sold, once we had a contract signed she became an invaluable source of communication with the buyers and their agent to see the deal through to closing. Her professionalism is unmatched as well as her patience and knowledge of the market. I will be delighted to hire Connie again for future sales and will recommend her to anyone I know looking to sell or buy a home.

I have bought and sold multiple properties and have worked with several other realtors so I have the experience to make a pretty accurate comparison. Connie is not only the hardest worker out there but she also knows how to get a deal done! I live in a very expensive gated country club community where houses can take more than a year or even two to sell, Connie sold my house in three month and she didn't do it by "low balling" the price. We got the full asking price! I also bought my new house with Connie. Connie is the best!

Her team worked so hard to create a great marketing program and we ended up selling to a wonderful family with two young girls who will grow up and make the next generation of memories, attend great schools and be in a neighborhood that we loved.
