Heritage Oaks Bank Executive Vice President and Chief Financial Officer Lonny Robinson has resigned, holding company Heritage Oaks Bancorp announced Aug. 19.

The Paso Robles-based bank hired Robinson in March 2014 to help with the Mission Community Bank merger and groom his successor, Jason Castle, Heritage Oaks Bank CEO and President Simone Lagomarsino said. Robinson resigned on Aug. 17.

“Jason is now prepared to take on the role of Chief Financial Officer and we are excited for Jason in this next phase of his career with us,” Lagomarsino said in a statement. “We appreciate all of Lonny’s hard work and wish him well in his next endeavor.”

Robinson will continue to consult with the bank to assist the transition, according to company filings.

Castle will receive an annual base salary of $200,000 and a $500 car allowance on top of incentives and stock options. He was previously the bank’s senior vice president and chief accounting officer. Prior to that, Castle was a consulting manager with Santa Maria-based certified public accountants Glenn and Burdette.

Heritage Oaks closed its $69 million acquisition of Mission Community on Feb. 28 of last year. Heritage Oaks Bancorp is the largest bank in the region with about $1.8 billion in assets.
