What My Clients Are Saying...
"We are incredibly grateful for the exceptional service Karen provided throughout the home-selling process. Her flexibility in accommodating our busy schedules and the valuable suggestions she made on optimizing the appearance of our house made a significant impact on its successful sale in the market.  From our initial meeting to the final steps of closing, Karen's proactive communication and attention to detail were remarkable. Her dedication to going above and beyond, ensuring every aspect was taken care of, made us feel confident and well-supported during what can often be a stressful time. Karen's professional yet caring approach truly made a positive difference in our experience. We wholeheartedly recommend her services to anyone looking to sell their home. Thank you, Karen, for making this process smooth and successful."  -2023 Seller Clients


"Karen went above and beyond to get our family home in Sudbury ready for sale, listed, and sold. When I say 'above and beyond' I am not exaggerating. She helped us find contractors for home repairs and yard work, and oversaw repairs herself when we were not available to be there ourselves. Karen worked tirelessly on our behalf and we could not be happier with her. Though we were probably a bit slower than the average home seller in getting our house on the market, Karen remained an advocate and ally in the process, making sure we were doing everything necessary to guarantee our house would close without complications. Which it did, just over a month after it went on the market. Really, we cannot say enough good things about Karen! If you need a seller's agent, she is truly one of a kind."    -2022 Seller Client

"Karen worked very patiently to help us find our home. She is honest, professional, tech savvy, and showed that she has both practical knowledge and a great deal of integrity. Because we were unsure which town to settle in, she patiently showed us homes in a wide area- working with us as a friend. She was incredibly responsive - even on weekends or evenings. She also has exquisite taste and knows people in the industry to help in everything from packing to renovation ideas. She is diligent and helped us make the right bid for our house. She will work hard for you as well! This is our fifth home and she is the best realtor we have ever worked with."   -2019 Buyer Clients

"Karen was absolutely wonderful. As first-time homebuyers, my husband and I had NO idea what we were doing. Karen was so patient and helpful; she walked us through the process step by step. From looking at different homes in our price range to the final closing, Karen was spectacular. She answered all of my crazy questions, she checked in regularly to make sure things were going smoothly, she responded to emails and phone calls within minutes - even on evenings and weekends! Plus, she recommended our attorney, Kimberly, who was also so incredibly helpful and responsive. We could not have hoped for a better team."   -2015 Buyer Clients

"It was a real pleasure working with you to sell our home of 26 years and find our next dream home. As you know, it wasnrsquo;t an easy path, but your patience and sage advice provided us with the confidence we needed to make it a reality and we couldnrsquo;t be happier. Your expertise and professionalism always was truly appreciated, but most of all we really got the sense you cared about helping us make the right move. We felt as if you were a partner with us, and thatrsquo;s what we really needed. Thank you for your long, dedicated hours and willingness to go above and beyond. We really appreciate what you did for us.   -2017 Seller/Buyer Clients
