Deborah Flanagan
Real Estate Broker/Owner
Mendon, MA
With nearly two decades of experience in residential real estate across Massachusetts and Rhode Island, Deborah Flanagan, co-broker/owner of C21 Custom Home Realty, leads strategic growth, drives performance, and defines the standard for client service in today’s competitive real estate market.
Her career began nearly 20 years ago with the purchase and successful renovation of her first investment property — an experience that built lasting expertise in property valuation, negotiation strategy, market analysis, and long-term real estate wealth building. That hands-on foundation expanded into brokerage leadership and business ownership, shaping how she develops agents, strengthens operations, and elevates the home buying and selling experience across a wide range of properties, including luxury homes and high-value residences throughout Massachusetts and Rhode Island.
Outside of business, Deborah is a proud mother of four and dog mom to two energetic pups. She understands firsthand that a home represents far more than a transaction — it is where families grow, milestones unfold, and life takes shape. That perspective informs her leadership style and her commitment to serving clients and communities with integrity....
