    • As a first time home buyer, needless to say I was feeling overwhelmed. However, The Gellman Teams professionalism, friendly personality and understanding of the neighborhoods I was looking at, as well as, a general understanding of the market, and a expert knowledge of the home buying process made buying my first home nearly effortless. They kept me updated, walked me through the procedures and really had my back 100% of the way. They had excellent negotiating skills which made me feel I was getting a great deal and made sure I was moving into a great house that wasnt going to be a money pit. Although it took some time to find the one, they found it. If you're considering buying your first home, I STRONGLY recommend using The Gellman Team. I promise, you will be beyond satisfied!!!!!

    • The Gellman Team made the home buying and selling process a breeze. In searching for a house, they were very accommodating with providing a wide variety of houses and helpful when we weren't quite sure what we needed. They were very involved with the closing process and guided us through the investigation and closing negotiations. With the selling process, we got an excellent price on our house and sold with minimal effort on our part. Throughout both processes, The Gellman Team was professional but approachable and very easy to work with.

      - Melissa Melkic
    • We absolutely loved working with The Gellman Team! They were patient with our search and how uber specific we were. They navigated a global pandemic with ease, giving us clear instructions for every step along the way. The Gellman Team was incredibly flexible when we would find a house we wanted to see and worked to accommodate our schedule flawlessly. And when we finally found our dream house, they helped us navigate that process perfectly and advocated for us as sellers. Wed work with them again in a heartbeat!!

      - justintrusty
    • I was very lucky to be introduced to The Gellman Team as my agent. They got my property sold with 4 showings and in that they got me 2 contracts including the one that got the house sold. I recommend The Gellman Team as they have a very strong negotiation skills and I felt they were passionate about what they do. I am extremely happy that I got my house sold amidst all the slowdown and the pandemic thanks to The Gellman Team.

    • The Gellman Team did a superb job acting as my agent in connection with a recent family home purchase. They are incredibly responsive and possesses knowledge of all aspects and nuances of real estate. Total professional who are a pleasure to work with throughout the entire process. Fantastic buyers agent for us.

      - Jeff Otto
    • Starting out, we "interviewed" a few different agents. Of those, The Gellman Team came out on top in all of the categories that Zillow lists, plus just general enthusiasm. They also felt the most genuine, if you know what I mean. The Gellman Team's greatest asset is how willing they are to help and how quickly they get things done. Also, if they don't know an answer off hand, they will not just give their best guess, they will double check with the team. Side note: The Gellman Team seems like a great and well organized company. We would absolutely work with The Gellman Team again and we have already referred someone else to them.

      - user31159908

      - kiba75
    • Not sure you could find a better Team. The Gellman Team was ALWAYS willing to go the extra mile. They'd even met us at odd times and on his own time on weekends to see homes. We received quick regular updates on the type of home we were looking for that went up for sale so we could sift thru the ones we knew were a waste of time for both of us. They helped us tremendously in the search for our new home. I would use them again no questions asked.

      - drobinson371

    • The Gellman Team was a dream to work with. They was always quick to respond and provide guidance. I had my heart set on a certain area and neighborhood for the school district. They scouted the exact neighborhood I wanted, down the the house model I loved. When there werent any sellers, they showed me other neighborhoods that I didnt even know existed in my desired area that had water and was easy to walk and play with children. When I finally wanted To make an offer on a home, they went above and beyond to make sure I was entering into a contract for a home that would completely meet our needs. They even contacted the president of the HOA to talk about what improvements they have allowed in the past.Without a doubt, The Gellman Team is an excellent realtor and I wouldnt hesitate to recommend them to everyone. If you want an agent who is attentive, knowledgeable about the areas in and around St. Louis, one who will look out for your interests and help you narrow your scope.

    • The Gellman Team was great! They helped us buy our home when we relocated from out of state into St. Louis. We didn't make it easy on them! We had a VERY short time line, a very long list of "must haves" and on top of that we were 5 hours away during almost the whole process. They were easy to work with and professional! There was never a question too small or an inconvenient time to reach them. The Gellman Team was incredibly insightful, had great tips for us and made the process as easy as possible even during a pandemic! I would recommend them to anyone in the St. Louis area looking to buy! 15/10

    • The Gellman Team are dedicated, connected professionals and we couldn't be more pleased with the process they took us through to find our forever home. Always positive and upbeat, They were proactive in sending us listings, and they listened to our feedback and made adjustments all along the way. Once we found our dream home, we knew we had to act very quickly. They were there every step of the way always available and always working in our best interests. I felt so relieved to have them in our corner looking out for us and knowing just what to do. From the search to the close, they were there to guide us and keep us ahead of the game. I trust them completely and am happy that while they are no longer my realtor, their my friend.

    • I can not express how grateful I am that I had The Gellman Team to help me through the process of buying my first home. They were so patient through my millions of questions and beyond transparent about everything during this process. When we viewed houses, I truly felt like they gave their opinion as if they were the one interested in the house and looked out for things that may have been a problem. They are extremely personable and flexible and willing to help with things totally beyond their scope or responsibilities. They were great at finding places that fit my needs and they found such an amazing home for me that I am so excited to make memories in. I seriously could go on forever about how great The Gellman team has been. I would recommend them to anyone!

    • I can't say enough good things about The Gellman Team. They were a great partner from our first meeting until I closed on my house. They armed me with information and good advice that led to securing a contract for the full asking price before the house was listed. The Gellman Team provided me with valuable resources, planning tools and prompt support throughout the process. I really did feel that selling my house was a team effort! Thank you!

    • The Gellman Team surpassed all of our expectations. This is the third house they have sold for our extended family and Tthe Gellman Team was proactive and professional every step of the way. They convinced us to invest in certain house improvements (and in fact acted as our project manager in so many areas) which increased the value of our house by 20-25%. Thanks for making this process relatively easy....we had three offers on the first day ....and all before the house was listed.

      - Max Barnett
    • My personal experience with The Gellman Team was outstanding. I was looking for an agent with an aggressive track record who was going to work for us and they certainly did not disappoint! Since it had been many years since we had purchased our own home, we realized that we needed someone with the knowledge and expertise to help us through this process. They explained everything from the very beginning and kept us up to speed every step of the way. His staff was exceptional. They too were very friendly and knowledgeable. They were always available to help answer a question. Their follow up was outstanding. All in all, we had a wonderful experience and will certainly recommend them in the future to any friends/family. Thanks again to all of The Gellman Team!!

      - Gwendol B
    • The Gellman Team was a serendipity on-line find as he answered an accidental click by me for more information. They stood by me for over 2 years feeding me information and advice on properties. They would send videos of homes for me promptly which really helped to alleviate the anxieties of selecting homes from afar and would periodically check to see how the sale of our current home was going. It was that extra mile they always went for in their service. If we hit a bump in the road on issues, they moved on, the service level never dropped nor did they complain. My family blessed them for the efforts they put into helping me. Their responses to my questions were honest, frank and always prompt. I never had to ask them twice for anything. Their negotiating skills are exceptional. If the selling agent dropped the ball, they picked it up. They put me in touch with exceptional teams for financing and inspections. Their knowledge of the area is excellent as was his capability to quickly send out comps in a rapidly moving market. They are certainly my family's choice for all of our future real estate needs.

      - Jane C Bucy
