Gibson Sotheby's International Realty


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.

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 1,000 offices in over 72 countries and territories. We offer 24 offices and over 350 sales associates throughout Boston, Greater Boston, the North Shore, the South Shore, and Cape Cod.

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 over 350 agents and 24 offices across Eastern Massachusetts. Larry and Paul possess a tremendous breadth of knowledge and business skills, making them sought-after speakers for large global audiences and valuable resources for our associate team. But more importantly, guided by a refreshing core of family values, Larry and Paul have revolutionized our business with a people-focused mission. They understand that the most strategic forecast of success is uniting compatible professionals who share the same principles and best practices, and by offering unique marketing support and a proprietary technology network for their associates. Today, Gibson Sotheby’s International Realty is the largest Massachusetts-based, independently-owned brokerage.
