"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, oversaw repairs herself when we were not available to be there. She 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, Karen is truly one of a kind." -2022 Seller Client, Linsey H.

"To say that Karen goes above and beyond for her clients is a massive understatement. There were many twists and turns in our search for the perfect place and Karen was there with us every step of the way. Her expertise, skill, and steadiness provided invaluable guidance through a very tricky and confusing market. There was no doubt she had our best interest at heart. I cannot recommend her highly enough."  - 2021 Family of Buyer Client, Megan C.

"First and foremost Karen is a skilled listener.  You combine that with extensive experience and knowledge of the real estate field and you have an understanding of what she brings to the client.  She is focused on your needs and wants---both articulated and unspoken.  She can translate that into interesting possibilities.  It was a warm and humorous experience searching for my new home.  Thank you, Karen."  -2021 Buyer, Sim C.

"Our experience with Karen has been a great. She has very good knowledge of the real estate market and is always prompt in guiding and helping. She is patient and also takes the time to elaborate on details for 1st time home buyers. Good knowledge on all aspects is her key strength."    -2020 Buyers, Mahidhar and Monika

"Karen is truly a gem. She was the calming and reassuring voice that my husband and I needed in the purchase of our new house. She expertly navigated our differing tastes and helped narrow us down to just what we were looking for. She is responsive, patient and kind. In the end we got our dream house for less than we wanted to spend in a neighborhood that is perfect for us. I would highly recommend Karen Guderian to all my friends."      -2018 Buyers, Sofia and Jose

 "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 wasn’t an easy path, but your patience and sage advice provided us with the confidence we needed to make it a reality and we couldn’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 that’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 Sellers/Buyers, Rich & Marilyn

 "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 Buyers, Paula and Ryan
