The following is a brief history of the agency written for Owatonna's Sesquicentennial which was celebrated in the summer of 2004.

Cline Tincher started the agency in 1912 in Owatonna and operated as C.A. Tincher.  The original office was in City Hall.  That didn’t last very long and they moved to another downtown location.  The first company represented was United States Fidelity and Guaranty. Their state agent was a gentleman by the name of Thiemer and for a while the agency was known as Thiemer and Tincher.

Oscar Peterson came in to the agency during the Depression (circa 1932) and they moved their office into what is now the Wells Fargo Bank building.  During this period they also worked for the Associated Mutuals which were part of the Kemper Group.  At that time Mr. Theimer left the agency.  The agency represented all mutual companies after the depression.

Ty Sincock came to Owatonna and joined the agency in 1947 after experience as a field representative for Safeco Insurance Company.  He stayed with the agency until 1977.  They had several downtown locations during this time and were in the building next to the Armory across from Federated since 1960.

Andy Wolf joined the agency in 1968 and purchased the interest of Oscar Peterson.  Thomas G Effertz joined the agency in 1975 and purchased the interest of Ty Sincock.  Mr. Effertz then purchased the interest of Mr. Wolf in 1983.

Terri Effertz and George Effertz joined the agency in 1984 and David Effertz in 1999.  David completed the full purchase of the agency in 2014.  Tom Effertz continued to work at the agency until he passed away in February of 2017 at the age of 77.


The agency has operated out of it’s present location at 285 18th St. SE since 1984.
