A Boutique Real Estate Advisory Firm
Founded in 2014, Columbus & Over Group (COG) is a boutique residential real estate consultancy and brokerage specializing in Boston’s most highly sought addresses.
We are based high above Copley Square in the Back Bay. Our company name is inspired by Columbus Avenue, the historic thoroughfare dividing the Back Bay from the South End, two tony areas of this great city. While our primary focus began with these tightly entwined neighborhoods, we have expanded over a decade in business to cover broader territory throughout Greater Boston with our agents having areas of hyperlocal focus that are unique to them.
