Real estate in Boston moves fast, and success requires a strategic mindset, deep market knowledge and strong negotiation skills. Sarah Fillmann, a global luxury specialist with Coldwell Banker Realty, has built her business on these principles, delivering exceptional results for buyers, sellers and developers alike.
With a decade of experience, Fillmann specializes in Charlestown, South Boston, South End, Beacon Hill and Back Bay. Having lived in Charlestown for 19 years and Boston since 1997, she offers firsthand knowledge of the city’s evolving real estate landscape. She works with first-time homebuyers, luxury clients and investors, but her expertise in developer representation truly sets her apart, helping maximize property value in competitive markets.
Fillmann’s career began in medical sales, where she became a top producer, before she transitioned to real estate in 2015. The fast-paced nature of the industry, combined with her love of working with people, made it the perfect fit. Known for her work ethic, energy and responsiveness, she guides clients through every step of the buying and selling process with a detail-oriented and solution-driven approach. Her strong network of attorneys, lenders and industry professionals ensures smooth transactions.
Recognized for her success, Fillmann earned Coldwell Banker’s International President’s Premier Club status in 2023 and International President’s Elite, ending 2024 as the No. 8 individual agent in Boston. She recently expanded her business, bringing on a colleague to provide even more personalized service. She believes real estate is about more than transactions; it’s about building relationships and helping clients achieve their dreams.
Outside of real estate, Fillmann supports Charlestown’s community fridge and East Coast Canine Rescue. She spends summers at her Cape Cod home; hikes with her rescue dogs, Lucky and Blueberry; and competes in dog agility competitions. When she’s not working, she enjoys exploring new restaurants, traveling and staying active outdoors.
