PNC Bank said it will expand its service offerings in greater Milwaukee as part of the conversion of National City branches. PNC acquired National City in October 2008. "We want to be a top three bank in this market," said Beth Wnuk, PNC's Wisconsin regional president. "That will be deposits and infrastructure. This is on a three- to five-year horizon. We will begin this year to put up branches, with more work in 2011 and 2012."
