Pinnacle Group has affiliated with Gibson Sotheby’s International Realty. The Wellesley-based real estate firm serves Boston’s MetroWest markets including Weston, Needham, Dover, Natick and Newton.

Pinnacle’s founding broker, Elaine Bannigan, along with Erin Abraham, Susan Bevilacqua, Danielle Comella, Alyson Karpowicz, Dede Long, Elyse Marsh and Cece Yan, bring decades of combined experience to their new brokerage.

Since 2023, the group worked under Douglas Elliman’s umbrella.

“We have respected Gibson Sotheby’s International Realty for many years, and the strength of its marketing, technology and global network made this a natural next step for our team,” said Bannigan in a press release. “We see tremendous opportunity to build on what we have established while bringing even greater reach and resources to our clients.”

Gibson Sotheby’s President Nicole Rideout Hartwick added, “Welcoming the Pinnacle Group is an important step in the continued expansion of our MetroWest presence. Their reputation for excellence, combined with our marketing platform and global connections through the Sotheby’s International Realty network, creates a powerful foundation for what comes next.”
