Mary Guertin helped us find our very first house and later helped us sell it. She was the perfect fit for us and our needs, and I couldn’t be more passionate about how seamless our experience and relationship were at every step. Mary is the ideal blend of professionalism, lifelong experience, and just the right touch of a 'keeping it real' attitude. Her transparency and, above all, HONESTY were essential qualities we looked for in an agent. We loved working with Mary so much that we obviously went back to her when it was time to sell. That experience reinforced our decision to stay with William Pitt Sotheby’s when we had to find a new agent in another town. We were lucky enough to find that town’s version of 'Mary.' Thank you, Mary, for being such a fantastic partner during such an important, emotional, and complex life event as buying and selling a home!

My wife and I were fortunate enough to work with Mary Guertin as both a selling and buying agent - she was a phenomenal partner throughout our search. We really appreciated her guidance, and genuinely felt that she had our best interests in mind. Our situation was quite unique in that our end goal was to build a home, but we first needed to sell. Mary helped us sell our home immediately; bringing in about 20 offers within 5 days of listing, and she was even able to solidify a unique rent-back agreement from the buyers which was extremely valuable for our situation. She then helped us obtain an accepted offer on a piece of land which included some unique contingencies, and required strong negotiating skills on her part. We closed last week and could not be more excited!! There is no way we could have done all of this without Mary’s help, and we are truly thankful for her partnership. Collin Wade

She is not my Realtor/Agent, she is one of the loves of my life . We have known Mary and her family for almost 40 years and we are proud to know her. She is a true professional and an even better friend and a great person. Nina & Charlue Constantine

Mary Guertin approached the sale of our home in a very professional and thorough way. We were impressed with the amount of research that went into putting together the correct asking price. We hadn't sold a house in over 30 years so we were rather naïve as to the full process. Throughout, Mary was responsive to all of our questions and concerns and by the time the actual sale was closed we regarded Mary as a trusted friend. William Sossei

In her words “you always up end where you belong” my response as long as you have God and a great realtor! Lester Rodriguez

Mary was great. This is the second time she’s been our realtor and as usual she surpassed our expectations. She was on top of everything and kept us updated through texts, emails, and phone calls. Her understanding of the market, the process, and the psyche of buyers let us sell our house quickly for a great price. She even kept our lawyer in check and made sure everything was done quickly and correctly. I can’t praise Mary enough and will continue to use her for next realtor need. She is awesome! Alan Webb

We were very happy with the support received from Mary. Paul & Stacia Laaksonen

Mary Guertin worked with us for many years. We were extremely picky and had a certain idea in mind. She helped us with several offers and walked us through the inspection and buying process. She was always a text or phone call away. She drove distances at early hours and evening hours for us. We can’t thank Mary enough for her dedication over the years. Brian & Marissa knees

Mary was very attentive and responsive to any of our asks. Amelia & Richard Perez

Mary was an absolute pleasure to work with. Her knowledge of the area, coupled with her work ethic and level of service exceeded all of my expectations. She even went so far as to assist with things that I, as the seller, should have had the responsibility to take care of. I cannot offer enough praise for Mary. She is truly a unique being in her field and that is a good thing for anyone that hires her. Glenn Forrest

Mary did a phenomenal job of helping us find the perfect house when we were a thousand miles away and unable to travel due to the pandemic. She was attentive and responsive to all of our questions and concerns, and we absolutely love the house she helped us buy. Will S.

Mary helped us find our forever home! It took us a little longer than most to find our home but Mary was everything you could hope for in a realtor. When if felt like we'd never find THE house. Mary rallied and reassured us we would and we'd know the moment we walked through the doors. She was right!! We've recommended Mary to friends over the years and they've had the same experience. Mary is genuine, patient and kind. You know she has other clients but when she's with you, you feel like her only client. She made herself available to us whenever we called, determined to help us find exactly what we were looking for. Marisa B

Mary Guertin not only was our agent to sell our home, but made the purchase of our new residence smooth and easy. We got more than our original price because Mary suggested we counter the buyer’s 1st offer. 5 star plus! Judith A Spak

Mary is a phenomenal real estate agent! She will work tirelessly for you. She listens to your needs and is a true professional. We were lucky to have found her when selling our home as well as purchasing our new dream house! Nicole and Dave Andrews

Not all Realestate agents are the same Mary is a true professional her understandind of the housing market as well our needs narrowed our search quickly. Her knowledge of our local area made a big difference in finding the right house . Scott s

Mary certainly deserves a 5-star rating of excellence. I have lived in the home of one of Mary's client for the past three years. During that time he engaged Mary based on her presentation and our knowledge of Sotheby's as an organization. She was patient and informed the seller who has lived in his home in Bethel for more than 40 years. She sent the reports of sales and trends keeping up with the real estate market in general and specifically in this area. During the recent pandemic and all the associated difficulties Mary found a buyer for the house and was excellent with advice on preparation and showing of the house and through the remedial work to be done prior to closing. During the sale of the house in Bethel I needed to find a suitable rental for myself, and Mary was instrumental in that. I have found an excellent situation in a house in Southbury, CT. I would recommend Mary wholeheartedly to anyone looking to work with a truly professional realtor with the personal touch need by clients in a transitional time. I have bought and sold 6 houses over the past 45 years and can say that Mary has been the best professional realtor in my experience. Ruth Blackwood

My experience with Mary Guertin has been excellent to say the least. She performed great service to the owner of the house in which I have been living the past 3 years in selling his house, and has found a wonderful, suitable rental property for me in Southbury as I transition from the house in Bethel. I have bought and sold six homes over the past 40 years, and I observed Mary to be the best realtor I have seen in any of those personal transactions. She kept myself and the owner of the Bethel house informed of the market over the past two years. In this season of the pandemic and associated difficulties she secured a buyer and has guided the seller through remedial work required as he prepares to leave his home of more than 40 years. She has been professional with a personal manner and gave great support in all ways. Selling or renting and moving is not the easiest process, but Mary has ameliorated and guided through the entire situation. I would recommend her wholeheartedly to anyone in need of a true professional. Ruth Blackwood (914) 672-3583 Ruth Blackwood

Mary is a true professional and I can recommend her services without a doubt. I give her a rating of excellent!! Nina Constantino

We have utilized Mary Guertin's services a few times now and would never consider another Real Estate Agent. She is not only a very close and dear friend and has been for over 37 years, she is also the most professional agent we have ever utilized in 14 moves between 4 different states. She is the best and you are lucky to have her. She has been an absolute blessing to us especially in times of need with moving/relocating. It is a great feeling knowing that she is on top of all aspects of the move, not just finding a home. We thank her for all of her hard work and dedication to her customers. The bonus is that we get to call her our friend. Charles Constantino Charles Constantino

Mary was very helpful in finding the home that my wife and I were looking for. She clearly listened carefully to what we wanted. Because of her we were able to quickly find a house in time to make an offer. I have already recommended her to others who are looking for homes. Theodore Timmel

Mary did a great job. She was very proffesional and it was a pleasure to do business with her on this very chalenging transaction. She was most helpfull and with out her this transaction would have failed. Thanks again Mary you are the Best. John Ashakr

We recently worked with Mary to purchase our new home in Bethel CT. Mary is a true professional and worked with us as the transaction took place during the worst of COVID-19. In addition to being fantastic to work with, she also took time with us to teach us about our new surrounding community so we can get comfortable quickly and start to build a home for ourselves. Simply put... Mary is the best! Jeffrey Bradbury
