Mark and Neil Gellman

  • Mark listed and sold my home

      We worked directly with Matt. Matt was awesome. Very direct and knowledgeable, professional. Sold our home in less that 1 month and half. Matt kept us in the loop on feedback and did a excellent job!

    • Mark helped me buy a home

        The Gillman Team really puts the special touch on the process. They are knowledgeable and make sure you feel informed and connected throughout the process!

      • The Gellman Team earned my business. They were willing to be interviewed before I went with them. They were always prompt in responding to my needs and questions. While relatively new to being a buying agent, if they didn't know an answer they would find it. I am confident The Gellman Team will continue to grow and each future client will benefit from them increasing knowledge and ability to listen to their client.

        - Bob Lazechko
      • The Gellman Team did a great job selling our house quickly. They took the time to get to know our house and neighborhood. They are very professional, and I would recommend them as a buying or selling agent.

      • I had a terrific experience with The Gellman Team as my buyer specialist. My home buying process was very fast, largely thanks to them. After viewing many homes online (I began my search before being vaccinated for Covid19), they got me under contract on one of the first homes we viewed together. In fact, they worked past eleven o'clock on a Saturday night on the evening I went under contract! As a first time homebuyer, I found that they had timely, honest, and realistic answers to my questions throughout the process, and I think I was smart and very fortunate to follow their advice on each step. As a buyer specialist, they take their responsibility to act in the best interest of the buyer in a serious and professional, yet courteous, manner. The Gellman Team was extremely hard-working and conscientious. I would feel very comfortable seeking out their expertise in the future or recommending them to a friend here in St Louis.

      • The Gellman Team was helpful and responsive during our pandemic move from the East Coast. They showed my husband multiple towns/homes during a St. Louis work trip, and later, they filmed walk-throughs of the homes that we were interested in (but unable to tour). They were patient during our search, and we ultimately found a great home for our family. We are thankful for the entire team.

        - jacqueline e Sullivan
      • This office is everything a real estate broker should be. Helpful prior to our decision to move to St. Louis, absolutely super in finding us a home that met all our needs and desires, and there for us when we had any questions, or needed recommendations, after we moved in. Loyal, knowledgeable, friendly and simply wonderful! The Gellman Team found and showed us two houses - both great - and we bought the second !! They had our back at every step of the transaction, always answered our questions and concerns, and was simply terrific to work with. (If only our selling broker back in California has been a tenth as good!) Highest recommendations!!!

        - Brian B.
      • The Gellman Team were a pleasure to work with. They were extremely fast and efficient (we listed the house in under two weeks and had an accepted offer within the first week of listing). They were very flexible and worked around our needs, and it is clear that they are very knowledgeable and have years of expertise in our local market. They went above and beyond to make sure we were taken care of, and pitched in to do things that homeowners have to do traditionally but we were unable to take care of because we were out of town for a few days during out listing week. Would highly recommend the team for both your purchasing and selling need (we both bought and sold our home with The Gellman Team).

        - quebad
      • The best buyer agent I have ever worked with. Not one of, but the very best! Top level knowledge and skills from every aspect. This house cannot possibly be purchased without The Gellman Teams professional work, and lots of hard work including weekend and evening.

      • We met The Gellman Team at an open house they were hosting after we almost took a break from purchasing our first home. We had two contracts fall through and pushy realtors wouldnt stop calling to try and get us to sign with them as our realtor for 6 months to a year (thankfully we never did!) But when we met The Gellman Team at the open house, they werent like any other realtors and if youre in need of someone to be on your side through the process, The Gellman Teams who youre looking for! They didnt follow us through the house, waiting to see if there was something we didnt like so he could try to convince us we did. They didnt talk to us the entire time we were in the home and really gave us the time to discuss it amongst ourselves and if we had any questions, he addressed them immediately. He was very patient with all our questions regarding the process, very knowledgeable about the market and the process for our 30 day close was seamless!! The Gellman Team was honest and didnt sugar coat or try to sway us in either direction regarding decisions, they just gave us the realities and facts. These attributes are what made the home buying process easy! When were ready to buy again or sell, well be having The Gellman Team as our realtor!

        - Hannah Miller
      • The Gellman Team did a great job for us. They were very helpful and provided great insight into the pros and cons of various properties. Ultimately, they found an ideal property for us.

        - dburnham2
      • We were very pleased to work with The Gellman Team in finding our home. The team was very knowledgeable about the area and had helpful information about the maintenance of the different houses they showed us. Anytime we needed them, they were there. The Gellman Team was always professional and answered any concerns we had, really listened to what we wanted. Even after our closing they helped us with some issues we were having. I would recommend The Gellman Team. You'll want them in helping you find your new home.

        - tuesdayb67
      • The Gellman Team was very helpful throughout the purchase of our first home. As renters we were completely clueless and The Gellman Team helped us identify problems and solutions and was always available for questions, no matter what time or day of the week it was. This year has been crazy for the real estate market but we still closed in 30 days with no hiccups. Thanks!

        - Annisa Kumerow
      • Absolutely incredible experience. This is my first home buying purchase and I couldn't have been more educated and well informed. Everything was planned well, put together and I always got reminders for my deadlines. The Gellman Team was always available and available to help. So happy with everything!

        - alcastiglioni1s
      • The Gellman Team did an excellent job. From the very beginning thy were always available and answered all our questions. The Gellman Team is very knowledgeable and made the whole process very smooth. I definitely recommend them to anybody looking to purchase a home.

        - blindfolded148
      • The Gellman Team is hands down THE BEST agent Ive ever had the pleasure of working with! They were knowledgeable yet down to earth, personable, and made the whole buying and closing process a breeze! They definitely went out of their way and above and beyond my expectations... which included helping with childcare recommendations and hand delivering a Thanksgiving pie! We first met them through Zillow in summer 2019. As out of state buyers, we appreciated their expertise and enthusiasm for the area. The Gellman Team showed us several homes both virtually and in person and kept in contact with us until our eventual sale. They made herself readily available at any and all hours with very little notice. They happily agreed to show any and all houses we were interested in. The Gellman Team was prompt, courteous, and professional with all information and required documentation. The Gellman Team was extremely easy going and pleasant to work with. I felt they truly cared and I felt comfortable asking any and all questions through the closing process. They made the house purchase and closing process enjoyable! I will recommend them to all of my friends and use them again for any of my real estate needs.

      • The Gellman Team has an infectious optimism and enduring patience. We are so lucky they could guide us in finding and buying our first home. Reviewing hundreds of homes online with them, going during lunch, evenings and weekends to tour houses as soon as they got on the market, and guiding us through our first home buying with three offers, The Gellman Team showed incredible customer service. They would respond within minutes to any question, comment, or worry we could think of. From the beginning, she understood exactly what our tastes were. I fell in love with every house I stepped into, but they were honest about the work that would be needed and the true value of the home. They negotiated with our interests in mind. I would recommend The Gellman Team to anyone buying a home, and especially to first time home buyers.

        - ryandrew3694
      • The Gellman Team was amazing to work with. They were very attentive and responsive to my needs. They gave expert advice. I will definitely reach out to The Gellman Team for my future needs Thank you for the support you gave during this transaction!

        - kathleenlipe
      • The Gellman Team did a great job in helping me buy a home. I was unsure at the beginning of the process as to what I was looking for, and they patiently assisted me in finding what it was that I wanted. They negotiated excellent terms when a place was found and kept me abreast of all that was happening. I highly recommend The Gellman Team as a real estate agent.

        - cpflederer
      • Throughout the process, The Gellman Team was very helpful. No matter how many times we changed our mind from buying a 30 year home to a five year home, they never judged and never asked questions about our situation. Whenever we wanted to see a house, they helped us or had somebody else come out to meet us. Regardless of the negotiations, compromising, and communication The Gellman Team was willing to listen. The Gellman Team was available to communicate through email, text, or phone call, and was very helpful throughout the entire process. In the end, we purchased our first home together and our 30 year home that we cannot wait to make our own.

        - amyruthshapiro
      • The Gellman Team was amazing helping me through my first home buying process. We looked at many homes and put in a couple of offers before finally finding the one. They explained every step of the process and answered all of my questions. They were always available to answer questions or take me to showings. I couldnt have asked for a better agent than The Gellman Team !

        - callahan sc
      • The Gellman Team has been great through the whole selling experience. Their response time is incredible. I would highly recommend them for helping you sell your home too. They even surprised us with a framed photo of the home we sold so we can remember our first home forever.

        - mdauksha6
      • The Gellman Team was an absolute pleasure to work with from beginning to end. Their professionalism is top notch. They are very friendly, knowledgeable, and never made us feel pressured or rushed in any of the decisions we had to make along the way. I would highly recommend their services to anyone looking to sell their home.

        - lyndiedauksha
      • I truly appreciate the work and dedication displayed by The Gellman Team in selling our home. They were always quick to respond to any questions and knowledgeable on making the sale happen. I would definitely recommend the team for any of your real estate needs.

        - Marianne Spencer
      • The Gellman Team is an exceptional realtor who went above and beyond to help us find the right home! If you're looking for a realtor, please do yourself a favor and call them. During the search, they knew the area well and provided us with a lot of keen insights into the market and local nuances. As we started focusing, they went above and beyond to give us what we needed to make a decision. The Gellman Team's a strong negotiator and we were impressed with how smoothly the offer, negotiation, and closing processes went. We especially appreciated how patient The Gellman Team was through the process, since we were somewhat picky as buyers and ended up taking a while to settle on a home. We never felt any pressure to buy, and we felt like the team was focused on finding us the right house, not just any house we were willing to buy.

        - Elunah
      • The Gellman Team was amazing to work with. They made the buying of our new home so easy. The Gellman Team is a great communicator and responds back very quickly. I highly recommend using The Gellman Team on the purchase of your new home!

        - Lorilu1221
      • The Gellman Team is NOT one of the best. They ARE the best. They were responsive to my emails or calls, no matter the day or time. The Gellman Team is very professional and their knowledge of the market is spot on. I took all of their recommendations and they paid off. And they proved to be the most valuable at the closing table. Again, The Gellman Team cannot be beat in any aspect of the sale process. If you are in the market to sell or buy you need to reach out to The Gellman Team. I have been thru three closings in the last four months. The deal with The Gellman Team was BY FAR the best experience out of the three, and I highly recommend the entire Gellman Team. It's obvious to me, the Gellman brothers know talent and how to close deals, even in this crazy year of 2020. Thank you to all who helped The Gellman Team help ME!

        - dixandrosie
      • I've had the pleasure of having The Gellman Team as my real estate agent twice after they were recommended to me from a friend. The initial occasion was when I was a first time home buyer. The Gellman Team was very patient and really took the time to explain things to me so I understood the entire process. They are extremely easy to work with and accommodating when looking for homes. Due to the favorable experience I had the first time I worked with them, I knew I would be well taken care of when it came time to sell my home a few years later. The Gellman Team made the process of selling my home from a different state as smooth as possible. They made all the arrangements when my home needed some repairs before closing, which was of great help as I was no longer physically in St. Louis.

        - sb alan lei
      • The Gellman Team was an absolute DREAM to work with. They took a lot of time getting to know us, our style and what we were looking for. They were eager to get feedback on the listings they were sending to us to determine if there were different things they should be looking for or to avoid. The Gellman Team handled our nerves, emotions, and many questions in the way a friend would, while still moving the process along. The Gellman Team was often sending us listings before they hit the market and getting us in to see them before others. They had such a knowledge of the market, the process, and how to navigate it all. We truly enjoyed the time we spent with The Gellman Team, and were sad when that came to an end. We felt that The Gellman Team had our familys best interests in mind and they took that stupidly. We couldnt recommend The Gellman Team more!

        - mccarty heatherl
      • Cannot recommend The Gellman Team more! They always responded to our texts and calls right away and was always available to show us houses same day (which is a must in this crazy market). Not only was their availability great, they knew exactly what we needed to do/not do to have a fighting chance when submitting an offer in a multiple offer situation. Because of their guidance and expertise, our offer was accepted by the sellers in an 8 offer situation! During our house tours, The Gellman Team was excellent at pointing out issues that my husband and I would never have noticed, and they steered us away from some homes with things that could have potentially been big issues down the road. This made us confident that they really cared about us as clients and wasnt just trying to make a quick sale. If you are debating at all about hiring The Gellman Team, do it! They also work for a company that has great perks including a free moving truck that you can rent. We had a great experience and will definitely use them again in the future if our housing needs change.

        - sabrinakohlberg
      • The Gellman Team was AWESOME to work with when selling our house. From beginning to end they guided us thru the process, insured we out in front of any actions, and made everything seamless all the way to closing. In addition, their market expertise and knowledge on prepping the house for listing was excellent. Highly recommend working with the team, and will do so again for any of our real estate needs. Thanks again!

        - derek r pierson
      • We interviewed several agents to sell our home and after 5 minutes talking with The Gellman Team we hired them. They made us feel so comfortable. The team did a great job marketing our home. It sold in 3 days. They are very honest made us feel like we were their only clients.

        - Jpalank
      • The Gellman Team was a joy to work with, really focused on what we were looking for. They spent time understanding what we wanted and went the extra mile to review properties for us, to make sure our time wasn't wasted looking at places that wouldn't work for us. I would strongly recommend the team to anyone looking to find their dream home!!

      • We had THE best experience working with The Gellman Team! They are so accommodating and easy to work with. There was never an awkward moment because The Gellman Team was amazing. We had so many laughs and good times during the process and all the while they remained professional. There were some tight deadlines to meet and more than a few bumps in the road, but their knowledge and persistence kept us calm and got the job done right on time. We can't speak highly enough of The Gellman Team! Definitely a fun and exciting experience that we will never forget!

        - Laura Thornton
      • The Gellman Team was always very quick to respond, very flexible with showing times and was very knowledgeable about the local real estate market. For a very complicated process, they made it seem easy. I would highly recommend using them.

        - scottdjackson2
      • The Gellman Team was great to work with and truly helped find the right house for us, not just one they could sell us. The Gellman Team got to know what was important to us and was patient with our questions. Highly recommend as an easy going but knowledgeable.

        - kohlberg13
      • The Gellman Team is a great team that makes your needs their first priority. They are always looking out for your interests and uses their experience to get you what you are looking for, and got us the best price possible. The Gellman Team helped us with purchase of our forever home and got us a location and price that I felt was top notch. I highly recommend them.

      • The Gellman Team help us look for a home in Wildwood. They were very knowledgeable about the area. We looked at many many homes. The Gellman Team was very patient to work with us. They brought us to homes that I know they predicted were not in the right location and not quite right but he would show them to us anyway. The Gellman Team was genuinely interested in our needs and not just making a sale. Great to work with. Easy-going personality and definitely knows the real estate Market, not just in Wildwood but other areas that we discussed as well.

        - Kristine Kraft
      • The Gellman Team went above and beyond for me with the purchase of my first home. They thought of things I didnt even know about. They asked for things that were important as a first time home buyer. They also made me feel very comfortable and taken care of. I felt at complete ease from start to finish. The Gellman Team even went above and beyond with coming to the house multiple time. They never made me feel pressured, in fact the team made sure to point out any concerns they saw along the way. Smooth process from start to finish. I would HIGHLY recommend The Gellman Team whether you are a first time home buyer like me or an experienced home buyer!

        - hrwestfall90
      • Throughout the entire process from home searching to home viewing to closing, The Gellman Team was very down to earth and helpful the entire time. They spent multiple weekend evenings showing us houses and answered all of our texts in a timely manner. The Gellman Team was very personable and did not pressure us in any way to move on a house we didn't feel comfortable about. We would recommend them highly and thank them for being such a friendly and consolidate team.

        - Abigail Chambers
      • The Gellman Team was a great! They were patient, responsive, and flexible to get us into showings. They helped us navigate a competitive buyers market well with a variety of negotiation options, letting us dictate how aggressive we wanted to be.

        - jmscales9
      • I recommend The Gellman Team. They helped find us options for the house we were looking for, and knew the area really well. They listened to our feedback. After a few showings, they knew what we would like and dislike about the houses. We were fighting for a house, and helped us get it. The Gellman Team was easy to get a hold of and followed up on everything we asked about. After we purchased the home, they helped us navigate this process as well, even after we had moved in and they probably didn't need to anymore.

        - janem722
      • Would recommend 10 times over to a friend. The Gellman Team is a true professional and goes the extra mile. Very responsive, engaging personality, and easy to deal get along with. Gives honest opinions and wants to help put you in the right house at the right price. They were very knowledgeable about the housing market in the areas I looked and pointed out numerous things I wouldn't have picked up on walking through a house.

        - mak4mc
      • The Gellman Team sent my wife and I a home listing that pretty well matched our needs in our desired area. They were able to get us in to look at the home an hour before public showings started. They had good knowledge of the neighborhood and had all the home info on hand to answer all our questions. The Gellman Team was real in the sense of pointing out possible updates needed along with the pros and cons of the house, not to mention she was very personable. With the team's quickness to act, due diligence and strategic negotiation skills we beat out the other 4 contracts on the table. Due to unfortunate personal circumstances (absolutely no fault of The Gellman Team's or the sellers) we had to terminate the contract. This is where they really shined. They helped us navigate the unsettling waters of backing out of our legally binding contract with very little repercussion to us. They worked very well with the sellers agent and title company while assuring my wife and I (who were very nervous and anxious) that all would be fine in the end... which was the case. The Gellman Team was the perfect mediator, in all sense of the word, in our situation. If they would have us, we would love to work with them again :) For that the team is a Five Star Real Estate Professional.

        - e conners
      • The Gellman Team was recommended to us and we were so impressed. They were responsive, knowledgeable, and happily took us to the numerous houses we wanted to see. They also made the entire process stress free because I was studying for the bar exam while house hunting. The Gellman Team wasnt pushy but aggressive when it was time to negotiate. Once we found the right house, they shoveled the snow off our driveway on move-in day to help us. We had our best buying experience yet with The Gellman Team!

        - Michael Brodsky
      • Could have not asked for a better realtor to work with on our first home purchase! We lived in a different state, during a pandemic, and The Gellman Team was available to show us houses via video call all over the city we bought in and surrounding areas, sometimes 5 houses a day! They responded immediately to all of our texts and really helped us find our perfect first home and feel comfortable since we could not see it in person before buying.

        - TrishaLink7
      • The Gellman Team was very patient throughout the preparation and marketing of my home. I valued their well calculated advice and immediate communication, providing updates and options for each dilemma that was presented. I would definitely recommend and will use them again.

        - neg1099mike
      • The Gellman Team guided us through the process and brought potential buyers into our home in the COVID environment. They had us leave lights on, doors open, and wiped down handles if touched. Most of all, they brought in great prospects and we sold our home prior to it officially being on the market. They answered all of our questions, had outstanding follow-up, and kept us informed throughout the process. I would definitely use them in the future.

        - Robert Lambrecht
      • The Gellman Team is very friendly, courteous, and professional. They were immediate with their responses to our many questions. The whole Gellman Team guided us through the whole process of our sale and closing make our lives easy and stress free. I would highly recommend the whole Gellman Team to anyone buying or selling a home.
