about our team

Brooklyn Experts. Boutique Service. Meaningful Results.

The Rosenberg Sackin Team is a top-producing partnership built on trust, community roots, and years of collaboration. When Erika Sackin bought her first Brooklyn co-op in 2006, Jan Rosenberg was her agent. That transaction sparked a friendship based on mutual respect and shared values—one that eventually evolved into one of Brooklyn’s most respected real estate teams.

Jan’s path to real estate began in academia. As a sociology professor and neighborhood activist, she brought a rare perspective to the industry—understanding housing not just as a transaction, but as a force for building stronger communities. In 2003, she founded Brooklyn Hearth Realty, a beloved local brokerage known for its personalized service and deep community ties. Erika, with a background in retail buying and set design, brought sharp instincts, relentless attention to detail, and a talent for guiding clients through complex decisions with clarity and care.

Their strengths are complementary—and their synergy is undeniable. After years working side by side at Brooklyn Hearth, they joined Douglas Elliman in 2017, forming the Rosenberg Sackin Team and quickly becoming top producers. Known for their honest advice, thoughtful strategies, and deep knowledge of Brooklyn’s unique housing landscape, Jan and Erika have guided hundreds of buyers and sellers to successful outcomes across co-ops, condos, townhomes, and multi-family buildings.
While they are particularly sought after for their expertise in Ditmas Park and Prospect Park South—where they both live and are deeply involved in the community—their reach spans all of Brooklyn, from co-ops in Flatbush to townhomes in Bed-Stuy. Clients value their grounded, boutique approach—where high-touch service, trusted guidance, and a passion for Brooklyn culture come standard.

Jan and Erika also believe in giving back. They proudly support neighborhood arts and music initiatives, including Operation Gig porch concerts, Artmageddon, and the Free Portrait Project, and they regularly partner with local entrepreneurs to help keep Brooklyn vibrant and connected.

Whether they’re advising a first-time buyer, stewarding an estate sale, or guiding a seasoned homeowner through a co-op board package, the Rosenberg Sackin Team brings unmatched experience, care, and heart to every client relationship.
