“Mary Ellen Gallagher is a Realtor’s Realtor, a very knowledgeable and reliable link to Westport. An excellent source of support, she provides full service-from obtaining a mortgage, home insurance to inspections, even checking in on the house while I was out of the country. On every front, I must say she has exceeded my expectations by leaps & bounds.

The best is that Mary Ellen has a full grasp of what your needs and requirements are. Every concern you might have, no matter how minor it is, is taken seriously. I say it once and I felt that she fully understood me without having the need to repeat nor elaborate. She brings up issues that should be raised. Hard to describe in so many words but I clearly felt comfortable working with her.

I work in (commercial) real estate and in private, have purchased/sold several apartments in NYC quite actively over the last 2 decades, so I will be the first to admit that I may not be the easiest customer to satisfy. Neither do I like pushy brokers. Having said that, I am 100% happy that I had met Mary Ellen during the early phase of my house search. From pre-to-post closing, she has been a true professional and I recommend Mary Ellen to anyone who is looking for a house in Westport.”

“My wife and I bought a home in Weston, CT with Mary Ellen. I say “with” because there is no way this transaction would have gone through without her. From helping us to find the right home (we didn’t even really know what we wanted) to walking us through the negotiation, to helping us close the deal, Mary Ellen was right beside us. I honestly now consider Mary Ellen to be a friend, and I can’t think of a better endorsement than that.”

“Mary Ellen helped us to buy and sell a home. She was kind, professional, prompt and very thorough. One of the things I appreciated most about working with Mary Ellen was how much research she did to help us decide on a listing price for the home we were trying to sell. She consistently went above and beyond, offering to do things like schedule repairs at our home if we couldn’t be there and bringing by documents that needed to be signed to make things easier on us.

I was always confident in the advice Mary Ellen gave us and would recommend her to anyone looking to buy or sell a home. The entire process was stress free and smooth”.

“We initially met Mary Ellen years ago at an open house. From that brief experience, we recognized Mary Ellen’s business-like approach would work well with us. One of the great qualities about Mary Ellen is that she really takes the time to learn about her clients. We weren’t initially looking to move, but always said we would do it if we found the right home. Over the years, Mary Ellen patiently showed us properties and learned about our tastes and needs. Because of that, she was able to find us the perfect place – the one that met our needs and felt like home all at the same time.

From there, Mary Ellen and her team at KMS worked together to come up with the right strategy. We sold our house within a week – above asking! Not only did she sell our home quickly, but she also worked tirelessly to negotiate a great deal on our new home as well.
Thank you for everything, Mary Ellen!”

Mary Ellen,
“THANK YOU for so many things:
~for seeing us through the hectic & stressful process of selling our house in Westport and finding and buying our house in Weston.
~for being a tireless advocate for us.
~for your support over the last 8 months and last, but not least,
~for becoming such a good friend throughout this whole ordeal.

You were right; this is a great house for us and your advice & guidance made such a difference. And we are so glad to be settled again (not counting the 30 or so boxes we haven’t unpacked yet)! Thanks for everything,”

“We were new to the area when we began looking for a home in CT. Our search began with visiting open houses. Of all the agents we met, Mary Ellen stood out. She listened to our needs, suggested potential neighborhoods, and gave us the tools with which to search. It was all about helping us, not selling to us. Meeting her was happenstance; picking her as our agent from among the others was a deliberate choice.

Mary Ellen stood by us through every phase of the home-buying process, beginning to end. From selecting search criteria, to actively looking, through the inspection, appraisal, negotiations and closing processes, her recommendations and advice were invaluable. Even beyond closing, we have relied on her referrals for service providers in the area.

We highly recommend Mary Ellen and her team at KMS Partners”.

“My wife and I would like to express our appreciation for the personal, and extremely professional assistance you provided us in purchasing a condo for my in-laws. Purchases involving an estate, where multiple personalities are involved, are difficult enough, but the added dimension of replacing real estate in a trust brings the complexity of the transaction to a higher level. Your knowledge of the Fairfield marketplace helped us find the perfect living situation for my in-laws. Also, your attention to detail, patience and experience dealing with multiple parties, including lawyers, was a source of comfort to the family. This is the second time you have assisted our family with the purchase of a property and, once again, you did not disappoint. We highly recommend you to anyone looking to purchase or sell a property in the Fairfield/Westport area.”

“Mary Ellen was right there to guide us and advise us on everything during our home search. She made it clear that our happiness was her #1 priority, and there was nothing she did that ever led us to think otherwise. She has become MUCH more than our realtor – she is our trusted advisor on all things Westport and more than that, we consider her a friend of the family!”

It was a pleasure working with you. The level of energy you expend on your clients is quite admirable! I thank you for all of your help in trying to keep (this) deal together.
