Wellington Managements Atlanta office no longer will handle asset management. Wellington is contacting clients to determine the fate of the $2.1 billion managed by the Atlanta office, according to sources. The five-person portfolio management staff there has dwindled to three managers, and the office will remain open for sales only. Dave Parker, former manager of the Atlanta office, left the partnership at the end of the year and joined Crawford Investment Counsel, and portfolio manager Valerie Diamond recently moved to the Boston office. The three remaining managers Carol Miller, Dennis Lacross and John Shepard will be leaving Wellington, although discussions were held with Wellington leadership about moving to the Boston headquarters. They are not partners of the firm. Wellington officials did not comment.
