Mark 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!
We had the best and the most professional service from The Gellman Team from start to finish with selling our home. They had excellent advice and was always a quick text or phone call away anytime we had any questions. Would highly recommend working with The Gellman Team.
- jldunemanWhen I first met The Gellman Team, I knew they would provide a professional experience with selling my first home. They guided me through each step of the process and gave me advice on how to best get the home ready for a sale. Once it was ready, they analyzed the market and provided me with a recommended sale price. Once the property was listed, they were easy to reach out to for any updates. Once offers came in, The Gellman Team was top notch on negoigating and getting me the best deal. They made my first home sale a breeze in an organized and efficient manner and stayed on top of everything every step of the way. Recommend The Gellman Team to anyone buying or selling!
- zuser20170208104302651The Gellman Team was very helpful and very quick to respond. They were honest and always gave helpful suggestions. Very knowledgeable about the housing market and very professional. We highly recommend The Gellman Team for anyone thinking about selling their home.
- Kathleen MahonThe Gellman Team is an amazing realtor. Their passion for finding the perfect home for others is transparent, as they listen and spends time getting to know their clients. Love their honesty, knowledge base, and strong work ethic!
- Kellen CohnThe Gellman Team has been so wonderful throughout the house buying process. My fiance and I have some pretty unique needs, including wheelchair accessibility (a quality that is not very easy to find without having to make some alterations), and I could not believe it when they actually found a house that perfectly checked all of our boxes! And they were able to find it very quickly after our initial phone call, saving us from the long and arduous process that I was warned house buying would be. Before we got started visiting houses, they talked us through the entire process and answered all of our questions with patience and sensitivity while keenly listening to our needs and concerns. My fiance and I were both completely new to this process and it would have been very easy for them to take shortcuts without us realizing it, or to steer us in the wrong direction, but they ended up leading us to what is truly the perfect home. Throughout the later part of the process, The Gellman Team continued checking in periodically to make sure things were going OK and to answer any questions that came up along the way. They were very attentive to our comfort level and never came across like they were just trying to make a sale. I feel truly lucky that we had such a positive experience and it's all due to The Gellman Team's expertise and professionalism! I will absolutely be recommending The Gellman Team to everyone I know who might be looking for a new home
- Gabriella GarberoThe Gellman Team, thank you for all of your help and guidance, of the sale of the condo. I appreciate everything you did. When Im ready to sell my home, I will be reaching out to you!!! Also the sketch of the condo, was like icing on the cake. So many memories to cherish. Thank you again.
- k hof 188878The Gellman Team is a member of the EXP real estate team, whom I had used in 2012 to sell a house in Chesterfield. Based on the great experience I had in 2012 with EXP, I contacted EXP to help me sell my house in St. Peters. The Gellman Team called me and came to my home shortly after I contacted the main EXP office. They came fully prepared with comparable sales, and a strong breadth of knowledge of the St. Peters real estate market. After thoroughly touring my home, we sat down and talked about listing price, marketing strategy, and what I need to do to ready my home for sale. Thanks to The Gellman Team and the support of the EXP team, my home sold for more than asking price while it was still in the "coming soon" phase of the process. They advised me of my options regarding the sale of the property, and the upside and downside risks of accepting an offer prior to having the home fully listed in the market. I ultimately decided to accept that offer, and the EXP team held my hand through the offer acceptance and closing process. Everyone I worked with was knowledgeable and professional. It was a very smooth process from start to finish. I highly recommend The Gellman Team and the EXP team to anyone considering the sale of their home.
- Barron MarschkeThe real estate market is cut-throat. You'll want The Gellman Team in your corner. They're a fighter, a true warrior. We were very pleased with the team. They have the heart of a teacher. It's refreshing to find someone willing to teach, coach, encourage you along this, sometimes overwhelming, journey. We would recommend The Gellman Team in a heartbeat. Even though we have no plans to move, we'll be sure to call them up if circumstances do change or we want to buy another house/rental house. Thank you!
- kperino5I called The Gellman Team by accident. Best mistake I ever made. They waeren't pushy, but matter of fact. I took their advice on selling the home and it was flawless. 8 showings with a solid offer the first day. There were a few unexpected glitches but we worked through them. I can't give him all the credit, because the whole team was solid and professional. Would highly recommend!
- easygoin724We were just thrilled with The Gellman Teams expertise in the entire process, top notch pro! We would recommend .The Gellman Team. There technology, efficiency and communication is incredible!
- joeyboimeThe Gellman Team was outstanding to work with - super knowledgeable, quick to respond/communicate, and helped me get a house at a price I didnt think Id get it at. Would recommend (and do recommend) them to anyone.
- gkt7w6The Gellman Team really wanted us to find our house. In the past other realtors let me do all the work but they actually were very proactive. Very grateful to have someone who actually cares help. I know that I can still reach out to The Gellman Team anytime even after the purchase because they are always available. Definitely helped relieve a lot of my stress while purchasing a house.
- zuser20170412The Gellman Team did a great job from start to finish, was very responsive, and had great attention to detail. I would definitely use them again for my next home.
- Andrew _The Gellman Team did a great job listing and selling our first home (and was also the one who helped us buy it as well)! They were very responsive and super friendly throughout the process, knew the area well, did great analysis, and made us feel reassured that we had the help we needed. Thanks!
- Elunahvery knowledgeable both of the area and the process and how to optimize everything from tours to inspections and making sure closing goes smoothly. very accessible and prompt. would highly recommend.
- Geoffrey PanjetonAs a first time homebuyer, I was unsure of what the buying process entailed. The Gellman Team helped navigate me through the entire deal from searching for the right property to making an offer and ensuring a smooth closing. They were exceptionally thorough with examining the details of the contract and ensured that I was protected in all aspects of the deal. I will definitely be returning when the time comes to sell my property and will be referring all my STL friends to The Gellman Team!
- rbedi90The Gellman Team is simply the best. From the first phone call, they were friendly, professional, and demonstrated a keen insight into all aspects of the market. The team was always available and arranged both in-person and virtual tours for us as we were moving from the East Coast. We were able to craft a competitive offer on a home with The Gellman Team's expertise and once accepted, helped us successfully negotiate the inspection resolution period. If you're looking to buy a home, look no further than The Gellman Team.
- yozampnWe were so impressed with The Gellman Team's knowledge of the houses in the area and the overall real estate market. They quickly identified what types of houses we wanted and was so helpful with walking us through the whole process. They really took a personal interest in us and our needs. Their communication throughout the entire process was extremely helpful. We highly recommend The Gellman Team. Thank you, we love our new home!
- Kathleen MahonI'm not sure what more you could ask for in an agent. The Gellman Team is super friendly, enthusiastic, calm, smart, always responds promptly, and has the support of a fantastic team that can take care of anything that comes up. Everything they said would happen, happened. I'd highly recommend them.
- gkauppilaWe cant speak highly enough of The Gellman Team as our real estate agent. Their professionalism, knowledge, honesty, integrity, and hard work ethics are very much appreciated and respected. We highly recommend The Gellman Team.
- maigulmazanThe Gellman Team is a great realtor. They will really fight for you when it comes to the negotiating process and is very knowledgeable. I had a very positive experience with them and would recommend them to anyone looking to buy/sell.
- ced9b3The 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 LazechkoThe 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.
- user9096826I 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.
- cshively35The 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 SullivanThis 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).
- quebadThe 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.
- 125885We 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 MillerThe 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.
- dburnham2We 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.
- tuesdayb67The 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 KumerowAbsolutely 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!
- alcastiglioni1sThe 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.
- blindfolded148The 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.
- zuser201803251The 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.
- ryandrew3694The 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!
- kathleenlipeThe 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.
- cpfledererThroughout 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.
- amyruthshapiroThe 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 scThe 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.
- mdauksha6The 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.
- lyndiedaukshaI 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 SpencerThe 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.
- ElunahThe 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!
- Lorilu1221The 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!
- dixandrosieI'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 leiThe 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 heatherlCannot 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.
- sabrinakohlbergThe 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!
