Principal Broker

Contact Brian

2020 is Brian’s 23rd year in the Nantucket real estate market, with 2 decades of experience Brian is a top producing agent on island. Originally hailing from Weston, Massachusetts, Brian came to Nantucket in 1996 intending to stay for just the summer. As often happens, he found himself being drawn in by the Island’s allure and immediately set about building a dynamic career spanning over 20 years in Nantucket real estate. Brian loves the puzzle and challenge of matching people to property, and believes that there is something for everyone here on Nantucket if you look hard enough. As one of the top brokers on the Island, to date he has participated in hundreds of millions in transactions and has been quoted by CNNMoney and Barron’s.

Brian truly embodies the Nantucket lifestyle, taking advantage of all the unique outdoor opportunities the Island offers and throwing himself into the local community. Seemingly squeezing 48 hours worth of work and activities into 24, Brian sits on numerous Boards and Committees, including the Maria Mitchell Association, and was appointed by the Nantucket Board of Selectmen to the Affordable Housing Trust. He lives on the Island year-round with wife Kate, son Fisher and daughter Piper.
