Gibson Sotheby's International Realty Opens New Office in South Dartmouth

#1 Massachusetts-Based Real Estate Firm by Sales Volume to Open First Office on the South Coast

Dartmouth, Massachusetts (February 13, 2023) – Gibson Sotheby's International Realty has announced its expanding presence in Southeastern Massachusetts with the opening of a new office location in the Padanaram community of South Dartmouth, Massachusetts, signifying its sustained momentum through the housing market shift. Located at 384 Elm Street, the addition marks the firm’s first office on the South Coast of Massachusetts and its twenty-sixth office statewide. 

Supporting this new office are several sales associates who bring extensive knowledge of the South Coast market, including Robin Ragle Davis, who joined Gibson Sotheby’s International Realty in 2020, and Maggie Tomkiewicz, Chris Hiller, and Margo Choquette of Team MCM, who joined the company in January 2023. Tomkiewicz, a broker associate and pillar of the South Coast real estate community, has been a realtor for thirty years. 

“Given the increased demand we are seeing for homes on the South Coast and beyond city limits, it made sense for us to expand to better support this growing market,” said Colleen Barry, Chief Executive Officer of Gibson Sotheby’s International Realty. “While the availability of homes is highly competitive, our company is able to provide the local expertise, white-glove level of service, and global marketing opportunities through our affiliation with Sotheby's International Realty®. It is our privilege to join this wonderful community, which we look forward to servicing in 2023 and the years to come.”

“Since 2018, Gibson Sotheby’s International Realty has assembled an outstanding team of professionals specializing in the South Shore and Cape Cod markets,” said Nicole Rideout Hartwick, Chief Strategy Officer at Gibson Sotheby’s International Realty. “The addition of our South Dartmouth office bridges these two regions and enables our associates to further service their clients. We invite our neighbors, friends and passersby to stop in and say hello.”

Earlier this year, Gibson Sotheby’s International Realty reported it served more than 2,900 clients and achieved $3.6 Billion in sales volume in 2022. It holds a $1.19 Million average sale price, the highest of the top five firms in Massachusetts.
