I first met Marsha about 15 years ago when she was recommended as a broker when we were looking to relocate from CT. Marsha was responsive to our needs/wants and got back to us quickly.
Unfortunately for Marsha we came upon and bought a "for sale by owner" shortly after starting to work with her. However, we have maintained a friendship with her ever since. Most recently I recommended her to a new acquaintance who was looking in RI for a relocation from MA. In this case Marsha worked with her, found a "buy" and finalized the purchase.
I am not in a position to rate her on "process expertise" or "negotiation skills" from personal experience, so have not done so.
However, I do know her work ethic, integrity, and she produces results. I recommend her highly.
