I worked with five-- yes five-- different Realtor in six years! It was one disappointment after another. I'm not sure where I heard about Mary,but I know in my heart that God had something to do with it. The first time I meet with Mary it was for 45 minutes and I knew that this time I was going to sell my house. She is a true professional! She told me what I needed to do to get the house ready to sell, two weeks later it was on the market and within three weeks I had two offers. DONE! Mary knows the so.NH. market very well, she works at it full time and takes her job and your feelings very serious! Paul S, Seller, 19 Shephard, Pelham
"If you are looking for real-estate professional with passion, a high level of integrity and professionalism, Mary is the one for you!! I have worked with Mary on three occasions. When relocating from Michigan to New Hampshire she assisted us in finding a rental property. When we were ready to purchase, and then when we were relocated out of the area and selling. She knows the area and the market very well. We had some very challenging transactions and she was able to help us remain calm and obtain the results we desired. She worked very hard on our behalf and earned great respect." Dan and Angel Sweezea, renters, buyers and sellers
Dear Mary, So Sorry that this note is so overdue. We think of you all the time and it reconfirms how special you are. We were very lucky to have you helping us to find a home. You were always positive, professional and a joy to work with. While this was a challenging time for us, we not only ended up with a beautiful new home (new to us), but we made a wonderful friend as well. We will never forget the caring and kindness that you showed to us, and we are happy when people ask us to recommend an agent. As far as we are concerned, you are the only agent for our friends and family. Again thank you so much. Rick and Valerie, Buyers, Windham
