William M. Mercer Investment Consulting will consolidate its Dallas operation into its Atlanta office by the end of this year. John M. Dickson, principal and head of the combined southern office, said all five Dallas-based investment consultants have been offered positions in Atlanta, which would bring to 20 the number of Mercer investment consultants there. Mr. Dickson said the move is designed to increase support for Mercer's growing client base in the South and Southwest. ``This strategy will best support that objective,'' he said.
