United Bank of Michigan President and CEO Michael Manica believes the economy was already on track for a good year in 2017. But the election of Donald Trump as president and his pro-business policies should boost the U.S. and the West Michigan economies higher, Manica said. A slow-growth economy that continues “without any signs to become considerably more vibrant” would surprise Manica in 2017. The Grand Rapids-based United Bank has 12 offices in West Michigan — six in Kent County, four in Allegan County and one each in Ionia County and Ottawa County, where a Jenison branch opened earlier this year. The bank had total assets of $596.2 million as of Sept. 30, up 15.8 percent from a year earlier, and deposits totaling $444.4 million, a 10-percent increase.
