Robert & Tracy Petch ~ Chesterfield Home Sale and Purchase
We have sold two houses with The Gellman team. Always great!!!! The last house we sold was a tremendous experience. We were very nervous because of the price point in time of year, but Neil told us exactly what to do to make it the most attractive to buyers, we did it. It sold quickly and for the reasonable price we’d wanted. But listen, it’s because it was Neil and The Gellman’s. The buyer’s agent told me she’d worked with The Gellman Team and knew that the deal would get done right. That’s big. Gellman gets it done!
Paula & Jason Farmer ~ 2 Chesterfield Home Purchases / Creve Coeur & Chesterfield Home Sale
We appreciated The Gellman Team’s professionalism and knowledge. You were fabulous to work with and we wish you much success. You are a great team!
Steve & Cheri Lasky ~ Town & Country Home Sale
Neil Gellman and his crew are AMAZING! Our house sold super fast at a great price. There is no better real estate team in the St. Louis area!
Regina & Stephen Stone ~ Brentwood Home Purchase / Clayton & Brentwood Home Sale
Mark and Neil’s diligence in finding the right place at the right price is unsurpassed by anyone else I have seen in real estate. Their strong desire to get things done right, negotiating skills and overall follow up were very much appreciated!
CJ Hagemann ~ South County Home Purchase
Mark Gellman and the entire team at Gellman has helped our family both sell and purchase a home. As a marketing professional myself, I can personally attest to their incredible customer service and attention to detail. Their priority was not just to sell us a house, they were focused on finding us the house that was the best fit for our family. Highly recommended and we would never work with anyone else.
Rebecca & Mark Reardon ~ High Ridge Home Purchase / Fenton Home Sale
Rarely does any of us work with a company that exceeds expectations from the time you meet to the time the sale is closed. The Gellman Team surpassed every expectation, fulfilled every promise and executed the sale of our home more efficiently and professionally than we could have imagined.
Niki & Thomas O’Connor ~ Wildwood Home Sale
Mark has helped my family and I on multiple residential listings and purchases . He has helped my mom on several different occasions, my mother-in-law and sister-in-law. Although I have my broker’s license, I will always have Mark represent me for my listings and home purchases. There is a reason he and his team are among the top in real estate sold in the United States. He is a true real estate professional.
A. Jeffrey & Sharon Moulton ~ Chesterfield Home Purchase / Clayton & Chesterfield Home Sale
Neil Gellman has assisted me with three properties in the last 5 years. He and his team are always professional, knowledgeable, and courteous, and they get the job done. I would recommend The Gellman Team to anyone who is buying or selling a home. You won’t be disappointed.
Drake Powers ~ University City & 2 Clayton Home Sales
The Gellman’s helped us find a house we couldn’t be more happy with! Not only did they listen to us about what we were wanting in a house, they helped us figure out what was most important, and they were attentive, eager and responsive during our search. Best of all they did a terrific job during the negotiation so we saved $ and got more than we anticipated. By far they vastly exceeded our expectations and will refer to anyone in need of a realtor.
Jeremy Kocher ~ Clayton Home Purchase
