I and my family have worked with Mary Ellen on many properties over the years, and she's been a tremendous resource in every instance. Mary Ellen goes above and beyond for you to ensure that you have the details you need to make an informed decision. Mary Ellen was overly gracious with her time in visiting each of the properties my wife and I were interested in. She's also been instrumental throughout the close process as well on this most recent property in Wilton, CT. Highly, highly recommend Mary Ellen!
