About Lesley

Since 2004, Lesley has successfully been selling homes in Brooklyn, yielding top industry awards and amassing a steadfast client following. Her astute knowledge of the real estate market and her champion negotiating skills has placed her among the highest ranking brokers in the neighborhood. Coupled with an honest approach and trusting manner, Lesley is both highly regarded and well respected among sellers and buyers alike.

Prior to joining Corcoran, Lesley held esteemed editorial positions in publishing at Conde Nast in fashion and photography. With an innate eye for detail and great appreciation for spatial relationships, it’s no wonder that her transition in to real estate was a perfect fit. Expertly styling and art directing property for resale is just another advantage she has over her competition.
Lesley’s success in sales has elevated her to NRT’s Top 3% Sales Associate in 2007-2014 and her proven track record and close ties to the community has yielded consistently increased sales since 2004.

A Park Slope resident with her husband and two daughters, Lesley is deeply connected to her community and is committed to helping others find the same contentment in a life-enhancing investment.
