State Auto Financial Corporation (STFC), an Ohio-based property and casualty insurance holding company, has appointed David Hosler as new vice president.

Hosler will work with business opportunities presented by RED (Risk Evaluation and Design), STFC’s affiliate in the alternative risk transfer market.

RED was part of State Auto Mutual’s 2009 acquisition of the rockhill insurance group.

Hosler joined State Auto Middle Market Insurance (SAMMI) as central zone vice president in 2008. He began his career as an underwriter with the Great American Insurance Group before becoming branch manager of AIG in Michigan.

Before joining SAMMI, Hosler served as director of branch operations for USG Insurance Services.

State Auto executive vice president and COO Mark Blackburn said, RED is already contributing significant growth to State Auto’s specialty insurance segment. Dave and the rest of the team will build on that momentum to further diversify our book of business.
