Who We Are

We are Atlantic Brokerage, a full service, privately owned real estate firm serving Cape Cod and Nantucket Island. Established in 2008 as Chatham Properties Group, the firm affiliated with Christie’s International Real Estate in 2022, becoming the exclusive affiliate for the Cape Cod towns of Provincetown, Truro, Wellfleet, Eastham, Orleans, Brewster, Chatham, Harwich, and the island of Nantucket. 

In June of 2025 we were honored to acquire the highly respected Wilkinson & Associates Real Estate brokerage of Orleans. We are thrilled to welcome their talented team and valued expertise in the Lower and Outer Cape markets to our growing network. 

Atlantic Brokerage is led by Doug Grattan, President and Director of Sales. Since our inception, our firm has achieved over $650 million in real estate sales. Under Doug’s leadership, Christie's Atlantic is recognized for its strong track record of providing top notch customer service to our clients and the properties we represent. Our attention to detail is unsurpassed. A winning combination of strong local knowledge with the national and international presence of Christie’s International Real Estate allows us to give exemplary service to all our clients.
