History of the Law Firm



We are delighted that you are visiting our Website to learn more about the Koeck Kirk &  Graves law firm.  If you are a client looking for assistance, you’ve come to the right place!

Our home is known to us as “Sauk Prairie”.  On a map, it is referenced as the twin communities of Sauk City and Prairie du Sac.  The area has been our law firm’s home for over seventy-five years.

The Sauk Prairie Office is located in the heart of the downtown business district in the Village of Prairie du Sac, overlooking the beautiful and changing Wisconsin River. Our office sits on the river bank and offers exceptional views of Wisconsin at its natural best.


The firm was founded in the 1930’s by Attorney Charles J. Ploetz.  In the early 1960’s the firm became Ploetz & Glynn, with the addition of Attorney Gerald T. Glynn.

In the intervening years Patrick J. Taggart joined the firm.  Taggart was later elected Sauk County Circuit Court Judge.
