The St. Martin Team at Barrett Sotheby's International Realty

The St. Martin Team works out of Westford under Barrett Sotheby's International Realty, and says on its own site it's served Westford and nearby towns — Carlisle, Groton, Chelmsford, Tyngsborough, Acton — for more than 30 years. Colleen Murphy is the one team member named in reviews; a 2025 review credits her with getting a friend through a difficult negotiation with sellers to close on a dream home, and a second calls her service excellent and says she knows how to play every move. Her Massachusetts real estate broker license is verified active in the state registry. The team's own site lists several more license numbers for other agents, in both Massachusetts and New Hampshire, that haven't been independently verified. With only two public reviews on file, there isn't much of a track record yet to judge beyond Colleen's — worth asking directly about the specific agent who'd handle a transaction.
