Jerry Bauer, chairman of the board of directors for both Security Financial Bank (SFB) and Security Financial Services Corporation (SFSC), the holding company that owns the bank, announced the promotion of Mark Oldenberg as chief executive officer (CEO) for both SFSC and SFB. Oldenberg, who succeeds Paul Rudersdorf, also has been appointed to serve on the board of directors for both SFB and SFSC. All were effective as of March 11, 2022.
“On behalf of the board of directors, we congratulate Mark on his appointment. We look forward to the vision, leadership and perspective he will bring to the role,” Bauer said. “We also thank Paul for his service and wish him the best.”
For the past few months, Paul and Mark have successfully worked side by side preparing for this transition.
“I leave the bank in a good place and with an experienced new leader in Mark Oldenberg,” Rudersdorf said. “Mark is a wonderful addition and will serve the bank well as SFB grows.”
Oldenberg, who most recently served as president of SFB, will continue to serve as president in addition to his duties as CEO. He has more than 25 years of community banking experience and earned degrees in both finance and accounting from the University of Wisconsin-Eau Claire.
“I am honored to help lead a team that is so passionate about providing exceptional service to our clients and communities,” Oldenberg said.
