Park National Corp. promoted Tim Lehman to COO and Jeff Wilson to chief administrative officer. This comes on the heels of the planned retirement of CFO John Kozak, whose early retirement relates to health issues, as he has been undergoing cancer treatment since 2009.

Lehman will be responsible for the bank's operations for deposits, consumer loans, technology and information services, according to the news source. Prior to the promotion, he reportedly managed only technology and information services. Wilson will be responsible for regulatory compliance and credit administration after the promotion takes effect.

The COO and chief administrative officer positions are newly created, a bank spokeswoman reportedly told the news source.
