Mary Guertin is a consummate professional — always helpful and willing to go above and beyond for her clients.

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!

Mary is smart, professional, and kind. She knows how to handle the sale of a house and is reliable, available, and has a wealth of knowledge. An expert in her field, she is a joy to work with.

Mary is wonderful. Very knowledgeable, presented the best option for me. By my side at any time through the entire process. Thank you so much.
