Kristin is one of the hardest working, honest, reliable realtors I know. She has done so much for so many organizations that serve people in need in Marshfield that may have fallen on hard times. She always one of the first business owners willing to donate her time, talent and money to make Marshfield the beautiful seaside community it is.

This business was recently setup by a race baiter, which is why we see all these nasty negative reviews. I know of many satisfied buyers of Kornerstones. Don't by into the hate.

Kristin helped us sell and buy during the COVID-19 pandemic and did it brilliantly. We had a great professional relationship making this process possible and less overwhelming. Whenever we had doubts or questions (even 10pm on Saturday nights) throughout the process Kristin was responsive and kept us assured that things would work out and we feel that they have. We are truly happy and grateful that we picked Kristin to help us. She was awesome!

We used Kristin to sell our house in Marshfield at the beginning of June. After meeting with multiple agents, we choose Kristin due to her strong knowledge of the local real estate market and how excited she really seemed to be listing our house. We listed during the middle of the COVID pandemic and Kristin did a fantastic job of setting up showings in a way that met best safety practices while still being efficient and getting as many prospective buyers in as possible. After a single weekend of showings, we had multiple offers and ended up selling for over asking price. Kristin was incredibly
