Gibson Sotheby's International Realty



Gibson Sotheby’s International Realty is Eastern Massachusetts’ premier real estate brokerage firm—and an affiliate in the Sotheby’s International Realty® network, the leading real estate brand spanning key markets all over the world. As one of the most influential Sotheby’s International Realty affiliates, we offer a world of advantages to buyers and sellers—including a heritage of hyperlocal expertise, a reputation for delivering white-glove service, exclusive media partnerships, global marketing reach, and access to a worldwide referral network consisting of approximately 1,075 offices in 81 countries and territories. We offer 27 offices and more than 450 sales associates throughout Boston, Greater Boston, MetroWest, the North Shore, South Shore, South Coast, and Cape Cod.

Betty Gibson, esteemed South End local and our pioneering founder, established our flagship office in Boston’s South End neighborhood in 1962. Gibson was instrumental in developing the growth and desirability of not only the South End, but the city of Boston as a whole. Today, our sales associates demonstrate the same dedication to the communities they serve and call home. Real estate is a people-centric business, and our engagement and relationships with our clients are of the utmost importance. Whether you are looking to sell your home or buy a new one, our associates are perfectly poised to guide you through every real estate transaction, both locally and internationally.

Behind every successful real estate transaction is a dedicated management team guiding our company, our world-class professionals, and the properties we represent. Under Larry Rideout and Paul McGann’s leadership since 2006, our company overcame the hardships of the economic recession and came back stronger than ever, growing from 80 agents and 3 offices to more than 450 agents and 27 offices across Eastern Massachusetts. Today, Gibson Sotheby’s International Realty is the largest Massachusetts-based, independently-owned brokerage.
