About Sean

With more than a decade working in Massachusetts real estate, Sean broke from the mold of the traditional brokerage, when he co-founded his own brokerage. Sean’s real estate career ran the gamut starting back in his days at Boston College: from sales to rentals, from Southie to Charlestown. Sean gained valuable experience working for larger firms but realized there were better ways to serve Boston-area clients. Sean brings his individualized touch to residential sales, zeroing in on Boston’s nuanced historic neighborhood.
