Cindy Cantrell

Residential Leasing Agent

“I was inspired to get my real estate salesperson license after a disappointing experience as a buyer. I got my start at Coldwell Banker Residential Brokerage in Winchester in 2001, worked for Charles Associates in Cambridge from 2008 until March 2020. I pride myself in providing expert service and an overall positive, stress-free experience. Outside of real estate, I’m a freelance writer for The Boston Globe and numerous other newspapers and magazines. I have also taught memoir writing classes and volunteered by reading to youth members at the Boys & Girls Club of Lawrence.”
