DK HEIBERGER LLP is a full-service law firm with a focus on real estate law and transactions. The firm’s partners Steven Sperber, Founding Partner of Sperber Denenberg & Kahan, Seth Denenberg, Eric Kahan and Jamie Heiberger Harrison, formerly of Heiberger & Associates, P.C. combined the successes of their firms’ respective 25-year history to form SDK HEIBERGER LLP in September 2020.

The partners have a long history together dating back to 1990 when Jamie, still in law school, started working with Steven and Seth at their original firm, Sperber Denenberg & Barany. In 1993 Eric joined as an associate and the four of us worked together until 1996 when Jamie ventured out on her own to build H&A. Over the decades, the Partners maintained close contact and shared referrals and business. It’s perhaps apropos that this well-respected group was created to aid an industry that was crushed by a global pandemic. Rather than let the coronavirus dictate our professional futures, the Partners decided to form a new firm featuring the best aspects of their respective practices. The result is the formation of SDK HEIBERGER LLP, a true full-service one-stop real estate law practice.

Each partner contributes their experience, perspective and strength to the team. Steven leads our expanding Supreme Court practice and residential and commercial litigation in Civil Court.

Seth co-manages the landlord-tenant practice and is well-known for his expertise in affordable housing, rent regulation, DHCR matters and low-income tax credits. Eric co-manages the landlord-tenant division while managing the back-office operations. Jamie spearheads the transactional division for purchases, sales, refinances, bank representation and commercial and residential leasing, and is an accredited instructor for Real Estate class credits. Individually, we are strong and solid lawyers; collectively, we’ve created a formidable real estate law group that caters to New York City including Manhattan, the Bronx, Harlem and Brooklyn, as well as Westchester and Long Island, including the Hamptons. We very much welcome the opportunity to serve and represent you and look forward to a longstanding and mutually beneficial partnership.
