Advisor Profiles

Charlotte Chu

Marketing Associate | Marketing & Design Co-op

From ultra high-end listings to luxury branding strategies, Charlotte brings a rare blend of big-city experience and marketing savvy to her role at Columbus & Over Group. Born and raised in Taiwan, she is fluent in both Mandarin and English and proud to incorporate her multicultural perspective to the Boston real estate industry.

Before joining COG, Charlotte worked with one of the top-producing teams at The Corcoran Group in New York City, serving as both an Executive Assistant and licensed Real Estate Agent. While there she toured impressive properties, like the most expensive condo in the United States located in Central Park Tower, giving her an experience that cemented her love for luxury real estate at the highest level.

Now based in Boston, Charlotte is completing her degree in Communication & Media Studies at Northeastern University, with minors in Marketing and Public Relations. On campus, she performs with the Kinematix dance troupe. She is also a certified scuba and free diver—always seeking energy, movement, and new perspectives both in and out of the office.
