Mr. Schinler, who will retire Dec. 31 after 25 years with the company, will remain in his current position until Mr. Kath is formally approved by the Integrity Board, then serve in an advisory capacity through the end of the year.

“We are pleased to welcome Darin to Integrity,” said Phil Urban, Integrity Insurance board chairman. “A longtime resident of Wisconsin, Darin will bring knowledge of both the insurance industry and the region to his role as president.”
