Real Estate


Our heritage began in Boston

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. Our qualified agents speak a variety of foreign languages, have advanced accreditations, possess deep knowledge of their local markets, and offer a proven track record of successfully selling fine properties at all price points.

Our Sotheby’s Heritage

Recognized worldwide, the prestige of the Sotheby’s brand is unparalleled. Established in 1744 in London for collectors of art and other fine possessions, the acclaimed auction house expanded to New York City in 1955 and is revered as a marketer of the world’s most treasured possessions. Sotheby’s International Realty inherited the iconic brand name in 1976, building upon its legacy by delivering unrivaled real estate service. Gibson Sotheby’s International Realty’s connection to Sotheby’s is our unique difference from the rest. We continue the tradition of exceptional service upon which Sotheby’s was founded more than two and a half centuries ago and maintain an outstanding alliance of marketing efforts that present our properties to the esteemed Sotheby’s clientele, offering targeted exposure to a coveted and influential audience.
