Leadership
Founded in Boston’s South End in 1962, Gibson Sotheby’s International Realty began as a boutique residential brokerage Domain/Domain with a singular passion for exceptional service. Over the decades, we meticulously built our reputation by focusing on integrity, market expertise, and deep community ties. By 2006, recognizing our steady growth and luxury‐market dominance, we partnered with Sotheby’s International Realty® and rebranded the office in honor of the founding owner Betty Gibson, a move that elevated our brand and gave us access to an unrivaled global network. Today, Gibson Sotheby’s International Realty is Massachusetts’ top MA based firm by sales volume, consistently achieving the highest average sale prices of the Top 10 Firms.
