Four months after an April executive shakeup, MFA Oil filled two key positions.

On Friday, Columbia-based MFA Oil named Jon Ihler as CEO, four months after former CEO Mark Fenner abruptly stepped down. The company also named Jeff Raetz as its new chief financial officer.

MFA Oil spokeswoman Ashley Bower and spokesman Adam Buckallew did not return calls seeking comment Monday.

Ihler, then-MFA Oil vice president of sales and marketing, was named interim CEO in April. He joined MFA Oil in 2001 and worked for its Big O Tires and Jiffy Lube franchises. Later he left the company to move to Colorado and run his own automotive business. Ihler returned to MFA Oil 2006 as the company’s business development manager.

In a news release, MFA Oil Board Chair Marion Kertz said Ihler is an experienced leader and the right person to lead the company going forward.

“Jon’s unwavering commitment to our cooperative, extensive knowledge of our business and energizing leadership approach will serve us well,” Kertz said in a news release.

Ihler said in a news release he is thankful for the opportunity and looks forward to leading more than 1,900 MFA Oil employees.

Raetz replaces former CFO Robert Condron. Raetz spent the last four years as the vice president and CFO of MFA Inc. Raetz also worked for eight years as the CFO of Fulton bridge fabricator OCCI Inc. Condron stepped down in June and described himself as “semi-retired” on his LinkedIn page.

Ihler said in a separate news release that MFA Oil was pleased to have someone with his track record serve as CFO.

“Jeff has extensive financial, operational and strategic experience and is well-versed in cooperative business practices,” Ihler said in the news release.
