"It's hard to imagine a more talented or pleasant real estate agent to work with on buying your home. From the start of the process Mary Gail was extremely helpful in what can often be a stressful process. She was patient, informative, and extremely available. Mary Gail was born and raised in Larchmont and is extremely knowledgeable about the area. She also has a keen sense of the market and was on top of the new homes coming on the market that met our needs. In the end, we found a wonderful home in large part due to Mary Gail's diligence and hard work. I can not speak highly enough about our experience working with Mary Gail. It was obvious that she cares a lot about her clients and helping them find the perfect home for their needs. Mary Gail is also a strong negotiator and maintains the utmost integrity. I highly recommend Mary Gail and will definitely use her again if we ever decide to sell!" - Brian and Becky, Larchmont

"Mary Gail was wonderful in every respect. Not did she help us get an offer on our home home within hours of listing it, but one that was above what we felt was a good asking price that had been established in a rigorous way. We had competing offers almost immediately and she struck a good balance between waiting to see what other offers would surface and accepting among them which ultimately produced an enhanced offer that we accepted. She also recommended staging the home and arranged for the stagers; a process that we felt really improved the way the home was perceived and was likely another key to getting such a positive outcome. And she identified some permit issues that required some alterations and might have delayed the closing had we not addressed them before listing and she helped as source the architect and contractor we hired to do that. As important, she was friendly, easy to work with throughout the process and was always very responsive.”" - Diane & Russ, Larchmont Manor

She asked great questions & took the time to understand what we were looking for as a family. She helped us negotiate in a practical way that took the emotion out of an emotional decision. She helped us be competitive while respecting our personal constraints and didn’t push us outside of our comfort zone. We would absolutely recommend Mary Gail to anyone who might be looking to sell their home or find their next one!" - Suzanne & Dan, Larchmont

What a difference! She just knew more, helped me stage the more, she handled stuff with town permits, she connected me to service people I needed (plumber, carpenter). What a huge difference it makes to work with an agent like this! Within the first week or so of listing it I had an offer for over my asking price.

"Rarely do you find a residential real estate agent in suburban NY, who really knows the market. Why? Because, even if they are "expert" in a market, they are too busy "selling" or "closing", and rarely listening! Mary Gail listens, studies, thinks dynamically and out works most of her peers in serving her client. She discovers buyer AND seller preferences, trends, and the particular needs of a client. Top notch, could not have done it without her!”" - Leigh and Bob, Mamaroneck
