For sellers & developers Keith achieves record prices, quick turnaround, and a smooth transaction from A-to-Z.
He is not only financially savvy, but also has excellent communication skills and leaves no stone unturned to achieve the best price in the quickest amount of time. Keith believes there is no substitute for experience and is honored to have been with Brooklyn’s Number 1 Brokerage, The Corcoran Group, since it opened its’ first Brooklyn office in Cobble Hill in 1999. Keith has sold hundreds of homes in Cobble Hill, Brooklyn Heights, Park Slope, Bed-Stuy, and practically every Brooklyn neighborhood.

Keith is the proud owner of a Brick Federal Townhome built in 1915 and has lived in Lefferts Gardens since 1999. After purchasing his home, Keith ended a 15 year career in Private Banking to help others achieve their Real Estate Dreams. In Lefferts Gardens alone, Keith is a staple and has sold more homes than any other broker and achieved record-topping prices. Keith’s extensive knowledge of Brooklyn’s neighborhoods and their versatile offerings make Keith a resource for the press too – he’s been quoted in the NY Times, WSJ, and online media countless times. Keith is happy to point that over 80% of his business comes from referrals who’ve worked with him over the years and wouldn’t consider any other broker because Keith’s knowledge, expertise, and thoroughness are unmatched.
Keith lives, breathes, and loves Real Estate! You can find him running in Prospect Park every morning and he’s always happy to share his love for and knowledge of Brooklyn with everyone.
