Kathy is a gem!

Kathy’s greatest strength is her care and personal investment. We are new to the area and have been out of the real estate world for a long while. We felt confident and secure through the whole process knowing we could depend on Kathy and that she was always looking out for us! She is kind, smart and is a true, well-connected local expert! We feel blessed to have had Kathy guiding us.

Exceptional, excellent, honest, knowledgeable, professional. I highly recommend Kathy Gagnon.

Our experience with Kathy was phenomenal. She helped us to sell the house in a very short period of time and again was very cordial, empathetic with our situation and allowed us to transition from one step to another very smoothly. Above all she was very kind and aware of the fact that we are seniors and treated with the utmost respect . She is an amazing person and we respect her professionalism at all times.
