Callon Petroleum Co. (NYSE: CPE) appointed Correne S. Loeffler as its interim CFO, the Natchez, Miss.-based company said June 22.

Loeffler joined Callon Petroleum in April from JPMorgan Securities LLC where she spent the past 10 years in the corporate client banking group, including her service as Callon's relationship manager since 2013. She will assume her new role at the Permian Basin-focused company from CEO Joe Gatto, previously CFO.

Gatto was named CEO of Callon Petroleum in late May following the unexpected death of the company's former leader Fred Callon. At the time, Gatto continued performing his current duties as the company's president and CFO.

Correne is a seasoned financial professional with a strong understanding of our business and well-suited to seamlessly transition this role for the company," Gatto said in a statement.

Loeffler graduated from Indiana University with a BA degree and The University of Texas with an MBA.
