Hastings Mutual Insurance, a regional property/casualty insurance carrier in the Midwest, has appointed William (Bill) Gregor as its new vice president of insurance operations.

Gregor is currently serving as the assistant vice president of personal and farm lines, the underwriter said.

The existing vice president, Keith Jandahl will retire by December 2012, after being in the insurance industry for 35 years and serving as vp of insurance operations at Hastings Mutual for more than 13 years.
