Gibson Sotheby's International Realty

Gibson Sotheby's International Realty is a Brewster-based brokerage handling residential sales and rentals as well as commercial brokerage, carrying the Sotheby's International Realty brand and a Better Business Bureau A+ grade (though it isn't BBB-accredited). The available reviews are limited and mixed. A 2025 Google review praised agent Josh for moving quickly to get a family into a last-minute rental in Dennis, and a 2023 review called it simply "best company and great people." But a Better Business Bureau review describes a more troubling experience: after signing a lease through DocuSign, the customer says an agent, Gioulianna, told them the landlords wouldn't countersign unless they immediately provided additional funds — the kind of pressure tactic worth asking about directly if you're renting through them. Beyond the reviews, several 2024 posts on a real-estate-deals forum note individual agents at the firm — different names each time — representing buyers in Boston-area multifamily sales in the $1.2–3.6 million range, and a 2018 post credited the firm with the most expensive condominium sale in Beacon Hill's history; these read as transaction announcements rather than customer accounts, so they speak to the firm's deal volume, not service quality. With a large firm like this, the person you actually work with matters more than the brand — worth vetting your specific agent given how differently that Google review and the BBB complaint read.
