My wife and I worked with Mary Ellen for over four years to find our dream home. She was an outstanding agent: patient, succinct, and tenacious. Mary Ellen learned and remembered our preferences, didn’t waste our time, and didn’t seem to mind that our search took so long. Most appreciative was that she was never “pushy” and didn’t try to sell us. She is a pleasure to work with!

Hefner Family – Bought in Westport 2017

Mary Ellen Gallagher sold our antique home in Weston, CT in 5 days. We listened to her advice on how to stage the house and the price to list. Everything was very smooth and Mary Ellen is extremely easy to work with. I highly recommend Mary Ellen Gallagher and her team, KMS Partners at Coldwell Banker!

Martha Mintzer – Sold in Weston 2017

I cannot speak highly enough about the sales and marketing of Mary Ellen Gallagher and her team of KMS Partners @ Coldwell Banker. She had the difficult task of trying to develop interest in a property of mine during the dreadfully slow 2016 calendar year. Despite sales activity grinding to a virtual halt during this period, Mary Ellen’s enthusiasm and high energy level never wavered. She worked with an excellent photographer to create top-notch marketing materials and the house was prominently featured in a number of publications. Mary Ellen arranged for numerous events at the property and I feel we had just the right number of open houses. Thanks to Mary Ellen’s efforts, as soon as we saw a slight pickup in activity, we had multiple buyers for the house and it quickly sold.

I remain most grateful to Mary Ellen and KMS Partners and give her my highest recommendation, and very much look forward to the next opportunity we might have to work together.

Mark Motyl – Sold in Westport 2017

I have worked with many realtors over the years and without a doubt, Mary Ellen was by far the BEST realtor I have ever found. She is incredibly knowledgeable about the market. She is assertive without being pushy and she is the most responsive Realtor I have ever met. She went above and beyond what was needed to sell my house including helping me deal with lawyers and contractors, who did work on my house before I put it on the market. Mary Ellen was very honest about what I needed to do to sell my house quickly and she was absolutely correct. Her attitude and enthusiasm were fabulous and we had great personal chemistry, which made the whole experience so enjoyable! There are not many realtors I can honestly say I would recommend but Mary Ellen Gallagher is one of a kind! I will never move again, but if anyone needs a realtor- look no further- Mary Ellen is the one!

Deb Hodes – Sold in Westport 2016

We sold our Westport home with Mary Ellen Gallagher in 2016. From helping us “stage” and prepare for listing to her follow-up after the sale, Mary Ellen was dedicated and thorough. Mary Ellen always goes the extra mile and brought in excellent video professionals, photographers, interior designers and craftsmen to prepare and market our home.

Mary Ellen is a pleasure to work with, has a strong business background and is part of an excellent KMS team. We highly recommend Mary Ellen and her team, KMS Partners @Coldwell Banker.

I have had the privilege of working with Mary Ellen on multiple projects preparing and staging her listed homes. Mary Ellen’s unwavering professionalism, ambition, and amiability make her the ideal listing agent. Constantly striving to address the needs and desires of her clients, she has left a significant imprint throughout Fairfield County. Collaborating on these projects with Mary Ellen has given me an opportunity to witness the impact she has had on her clients’ lives. Her clients not only value her dedication, but appreciate the level of comfort she provides, resulting in their utmost trust and confidence in her as their agent. I have witnessed first hand the enthusiasm from her clients as she collaborates with necessary experts to address the transformation process of preparing homes for the marketplace. The outcome of these improvements results in the sale of their homes. Mary Ellen is a pleasure to work with, and I am convinced you would be delighted to have her represent you and your property as your listing agent. Hiring her and her expertise to search for your dream house is a decision you will not regret!
