Exchange Bank has agreed to acquire Iowa-based American Trust and Savings Bank’s California Trust and Wealth Management operations.
The deal, whose financial terms were not disclosed, is pending regulatory nod.
As part of the deal, American Trust’s senior trust officer Cathleen Colgan and trust administrative assistant Jill Solle will move to Exchange Bank.
The duo will remain based in their existing San Mateo office.
They will now be responsible for building new client relationships within the advisory community.
Exchange Bank president and CEO Gary Hartwick said: “We believe the geographic expansion of our Trust & Investment Management department into the South Bay is a natural extension of our long-standing trust business.”
