Chris Simms and Steve Greiff will be co-presidents of the division, according to a report in the St. Louis Business Journal. Simms previously served as senior vice president of capital markets; Griff was senior vice president of mortgage operations.
The former head of the mortgage unit, Brian Boyles, resigned in October.
The $1.3-billion-asset Pulaski announced in October that a commercial borrower had defrauded the company of $7 billion in loans. The fraud forced Pulaski to lower its fiscal-year earnings by nearly a third, to $8.3 million.
Pulaski has 13 branches in Missouri, according to the Federal Deposit Insurance Corp.
