David Winoker, the real estate executive who died Friday in a skydiving accident in Ulster County, N.Y., grew his leasing agency business rapidly over the past year, picking up at least three new buildings. Winoker, 49, the president of the Midtown-based commercial real estate firm Winoker Realty, was awarded the leasing agency at the firm’s biggest building, the 382,269-square-foot 1450 Broadway, in June 2011. The husband and father of three also won the assignment for at least two other properties over the year, for a total of more than 500,000 square feet, a review of data from CoStar Group shows. [more]
