Some banks make heavy use of personal bankers under the belief that having a dedicated person to help with problems would make a difference in the customer experience. Up until this month, we believed this notion. We were also jealous of other banks that use a personal banker model. A survey we conducted last week shows that approximately 22.4% of bank customers either have a personal banker assigned to them or have a banker that they have selected that they use as a personal banker. However, the belief that a personal banker helps customer satisfaction may be misplaced.
