Lesley Semmelhack

Lesley Semmelhack is a Brooklyn real estate agent with The Corcoran Group, bringing 22 years of experience representing sellers, buyers and developers in the sale and purchase of townhouses, co-ops, condos and new development. Her practice centers on Park Slope, Brooklyn Heights, Cobble Hill and Carroll Gardens, with an established footprint across Prospect Heights, Boerum Hill, Williamsburg, DUMBO, Fort Greene and Clinton Hill.

Her approach is bespoke in the truest sense: a strategy shaped around each home and each client, with Lesley personally involved from the first conversation through closing. Sellers receive thoughtful preparation and precise positioning. Buyers gain an experienced eye for character, potential and value. Developers work with a partner who understands how design decisions translate into a compelling home.

With an editorial publishing background, Lesley has a high-end design sensibility that remains a signature of her practice. That perspective informs every stage of a listing, from preparation, staging and art direction to photography and market positioning, helping buyers understand a home's distinction and imagine their lives within it.

In Brooklyn, Lesley has contributed to the design and visual direction of nearly 20 new development projects alongside their marketing and sale, while bringing the same attention to resale properties through deep neighborhood knowledge, pricing strategy and skilled negotiation.

Her experience has earned national and local recognition. Lesley has been involved in more than $2 billion in real estate transactions, has ranked among RealTrends' Top 10 Verified Individual Brokers by Volume in Brooklyn four times, most recently in 2026, and among the top 1.5% of real estate professionals nationwide. She is also a four-time member of Corcoran's President's Council, reserved for the firm's top 1% of producers.

For clients, the experience is personal, considered, and calmly managed. Lesley brings clarity to complex decisions, conviction in negotiations and accountability at every detail, backed by The Corcoran Group's marketing reach and resources.
