After a bit more than a month as president and chief executive of Philadelphia Insurance Co., Sean Sweeney has stepped down "for personal reasons," the Bala Cynwyd company said.
Sweeney's replacement is Robert D. O'Leary Jr., who had been executive vice president and chief marketing officer.
Philadelphia Insurance, which was sold to Tokio Marine Holdings Inc. for $4.5 billion in 2008, announced Sweeney's promotion to CEO from chief operating officer in November. The promotion took effect Jan. 1. Sweeney is a nephew of company founder James J. Maguire.
