Lee Rosner, Sole Owner of Coldwell Banker Commercial Rosner & Associates
The former company, Coldwell Banker Commercial Tsunis Rosner, with Rosner, John Tsunis and Jim Tsunis owning equal shares, was begun in 1998 when the Coldwell Banker Commercial name first established a presence on Long Island. Rosner's recent move came about as part of a buyout plan that began in Spring of '03 when he bought the one third share that was held by John Tsunis. Jim and John are cousins in a family that has, through the years, contributed many players in the real estate business on Long Island. However, as Rosner's continued to concentrate on the original objective of servicing the corporate real estate client, the direction of the Tsunis cousins gravitated to real estate development.
