Advisor Profiles

Jamie Gaines

Real Estate Advisor


Jamie landed in Boston in 2017 and immediately fell in love with the city and its culture. She began her career in real estate as a rental agent and learned a tremendous amount while helping hundreds of clients find their home in neighborhoods all over Boston and Brookline. Between 2017 and 2018, she completed 135 rental transactions in 13 neighborhoods of Boston.

She has been an active member of the COG sales team since 2019 completing $10’s of millions of sales transactions in her young career. Her commitment to understanding each market and executing the deal process is self-evident. Her devotion to clients is second to none. Jamie’s excellent communication skills and friendly approach make working with her seamless and enjoyable.

In 2020 and 2021, Jamie spearheaded efforts to sell out a 9 unit building in East Boston and a 28 unit building in Watertown. Each building set record breaking pricing in its respective neighborhood. Her ability to connect with clients, vendors and brokers alike has made her invaluable to the team.

Jamie graduated from Proctor Academy in NH and continued on to Gettysburg College where she received a BA in Health Sciences and Business. Jamie now resides in the Seaport area. She loves to explore the city and is constantly seeking insider knowledge and access to new things and places. She completed the (virtual) Boston Marathon in 2020. Don’t challenge her to a ski race!
