About Us

Real estate business focusing on relocations into our community.

If you are looking to move to Maine or purchase a vacation home there, we can help. Sue is a licensed real estate agent in both Massachusetts and Maine. Sue has been a real estate agent since 2014 after watching her home sale and feeling there was a better way. “I felt abandoned in the process, and my agent made me feel I was bothering her. I swore I wouldn’t let a client struggle.” Her goal is to help people find their dream home and be happy where they live.

“I’ve been affiliated with several real estate companies and franchises, giving me a broad perspective in the industry. I recognize quality agents and am comfortable helping getting to the closing table.”

She began her real estate career in 2008 as an office administrator, where she used her graphic design background helping agents. While she was born and raised in Newton, she’s lived in Southborough since 1999. “I was drawn to Southborough for the small-town feel, and my two children enjoyed all the school system has to offer." In 2021, Sue bought here second home in Kennebunk. She loves spending time in the community and near the water.

She forms half the team in the GK Group, working with Gary Kelley. She and Gary complement each other well. He loves the systems of the homes and the listing process, while she loves the design features and touring houses with her buyers/sellers.
